When you overload the circuit in your house by turning on too many different appliances at once and your power to the appliances you are using shuts off, the electrical device that tripped and caused the power to stop to the overloaded circuit is an example of a fuse. In some countries, because of the high fault current available where these fuses are used, local regulations may permit only trained personnel to change these fuses. The associated high pressure (often greater than 100 atmospheres) and cooling gases rapidly quench the resulting arc. This should be higher than the prospective short-circuit current. It comprises a strip or a metal wire that dissolves when the heavy flow of current supplies through it. Swe-Check: The Circuit Protection Specialists. A vented fuse in which the expulsion effect of the gases produced by internal arcing, either alone or aided by other mechanisms, results in current interruption. The high temperature necessary to fuse cement clinker makes this process difficult to accomplish commercially, but it has many inherent merits and may be the process of the future, displacing the rotatory method. Meaning of FUSE. Automotive fuses can be mounted in fuse blocks, inline fuse holders, or fuse clips. The voltage drop should be taken into account, particularly when using a fuse in low-voltage applications. Modern consumer units usually contain miniature circuit breakers (MCBs) instead of fuses, though cartridge fuses are sometimes still used, as in some applications MCBs are prone to nuisance tripping. It contains a piece of wire... | Meaning, pronunciation, translations and examples ‘Electrical systems still using fuses may work just fine.’ ‘For spare carry a set of drive belts, hose pipes, loose electrical wire, insulation tape, extra fuses and coolant’ ‘The electromagnetic pulse generated by the test led to power surges in electrical cables in Hawaii, blowing fuses… There are two styles of fuse base that can be screwed into these units: one designed for rewirable fusewire carriers and one designed for cartridge fuse carriers. Fuse bodies may be made of ceramic, glass, plastic, fiberglass, molded mica laminates, or molded compressed fibre depending on application and voltage class. A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and (usually) enclosed by a non-combustible housing. Fuses for commercial or industrial power systems must have higher interrupting ratings, with some low-voltage current-limiting high interrupting fuses rated for 300,000 amperes. fuse, safety fuse. a small wire or device inside a piece of electrical equipment that breaks and stops the current if the flow of electricity is too strong. The PPTC thermistor is self-resetting in that when current is removed, the device will cool and revert to low resistance. In electronics and electrical engineering, a fuse (from the French fusée, Italian fuso, "spindle" [1]) is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. Fuses have been used as essential safety devices from the early days of electrical engineering. This standard applies to fuses rated 1 kV or less, AC or DC, and with breaking capacity up to 200 kA. Various kinds of proximity fuzes are designed for various targets such as planes, missiles, ships at sea and ground forces. Automotive fuses can be classified into four distinct categories: Most automotive fuses rated at 32 volts are used on circuits rated 24 volts DC and below. The speed at which a fuse blows depends on how much current flows through it and the material of which the fuse is made.Manufacturers can provide a plot of current vs time, often plotted on logarithmic scales, to characterize the device and to allow comparison with the characteristics of protective devices upstream and downstream of the fuse. Low-voltage high rupture capacity (HRC) fuses are used in the area of main distribution boards in low-voltage networks where there is a high prospective short circuit current. When a fault or overload current flows through the fuse wire, it will become hot and melt. The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Blade type fuses often require the use of a special purpose extractor tool to remove them from the fuse holder. Some Wylex standard models were made with an RCD instead of the main switch, but (for consumer units supplying the entire installation) this is no longer compliant with the wiring regulations as alarm systems should not be RCD-protected. translation and definition "fuse", Dictionary English-English online. The melting I2t is proportional to the amount of energy required to begin melting the fuse element. A cable limiter is similar to a fuse but is intended only for protection of low voltage power cables. These types of fuse are used on equipment such as motors, which can draw larger than normal currents for up to several seconds while coming up to speed. The current-time characteristic of a fuse cannot always be correlated with that of the protective device. What does electrical fuse mean?

Apart from protecting equipment, they are also used as safety measures to prevent any safety hazards to humans. Automotive fuses are used to protect the wiring and electrical equipment for vehicles. Fuses are widely used for protection of electric motor circuits; for small overloads, the motor protection circuit will open the controlling contactor automatically, and the fuse will only operate for short circuits or extreme overload. Chances are that server has a currency and a shop. Expulsion fuses are defined as follows: Expulsion fuse. These are still used in consumer units in some parts of the world, but are becoming less common. As nouns the difference between fuze and fuse is that fuze is an alternative spelling of fuse in the sense of a detonator while fuse is (also'' fuze ''in us ) a cord that, when lit, conveys the fire to some explosive device. Semi-enclosed fuses are fuse wire carriers in which the fusible wire itself can be replaced. Some fuses are designated high rupture capacity (HRC) or high breaking capacity (HBC)[6] and are usually filled with sand or a similar material.[7]. Plasma inside the glass tube may continue to conduct current until the current diminishes to the point where the plasma becomes a non-conducting gas. In the field of electronics or electrical, a fuse is an essential device used in various electrical circuits which gives the protection from the overcurrent. 1 fuse / ˈ ... also US fuze: a mechanical or electrical device that causes a weapon (such as a bomb or torpedo) to explode. Fuses can be built with different sized enclosures to prevent interchange of different ratings of fuse. When the surrounding temperature gets too high, the composition melts and allows the spring contact mechanism to break the circuit. Definition of fuse written for English Language Learners from the Merriam-Webster Learner's Dictionary with audio pronunciations, usage examples, and count/noncount noun labels. What does fuse mean? A miniature time-delay 250 V fuse that will interrupt a 0.3 A current at after 100 s, or a 15 A current in 0.1 s. 32 mm (1 1/4") long. These fuses are intended for installations following Canadian Electrical Code, Part I (CEC), or the National Electrical Code, NFPA 70 (NEC). IEC & IEEE/ANSI Symbols of Fuse . Fuse definition, a tube, cord, or the like, filled or saturated with combustible matter, for igniting an explosive. It may be installed in a circuit-breaker box with a door. Another word for fuse. Make sure that the correct fuse is fitted. Connecting fuses in series does not increase the rated voltage of the combination, nor of any one fuse. [2], A fuse was patented by Thomas Edison in 1890 as part of his electric distribution system.[3].

Indicating disc — a coloured disc (flush mounted in the end cap of the fuse) falls out when the element is blown. To blend two or more substances by melting. In North American standards, the fuse is the replaceable portion of the assembly, and a fuse link would be a bare metal element for installation in a fuse. Pole-mounted distribution transformers are nearly always protected by a fusible cutout, which can have the fuse element replaced using live-line maintenance tools. Fuses for low voltage power circuits may have bolted blade or tag terminals which are secured by screws to a fuseholder. Phone: +61 3 9521 6133 Fax: +61 3 9521 6177 Web: www.swe-check.com.au . Later those pads fuse with the anterior end of the centrum of the vertebra to which they belong; where the vertebral column is rendered inflexible, the disks are ossified with the centra and all trace of them is lost. Inside the fuse is a metal strip that is connected to both metal ends of the fuse body. Short circuit, overload or device failure is often the reason for excessive current. noun the hole in a shell prepared for the reception of the fuse. The element must not be damaged by minor harmless surges of current, and must not oxidize or change its behavior after possibly years of service. Electric fuse was invented by Thomas Alva Edison in 1890. Similar appearing fuses may have significantly different properties, identified by their markings. Something of an oddity, a circuit-breaker fuse screws into an Edison socket on the fuse panel, but rather than having a metal-alloy filament, this fuse has a mechanism that can be reset by pushing a small button on the face of the fuse. In a multi-phase power circuit, if only one fuse opens, the remaining phases will have higher than normal currents, and unbalanced voltages, with possible damage to motors. A proximity fuze is a fuze that detonates an explosive device automatically when the distance to the target becomes smaller than a predetermined value, or when the fuze and the target pass by each other. The standard ampere ratings for fuses (and circuit breakers) in USA/Canada are considered 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000, 5000, and 6000 amperes.

This is not the case with fuses, which rely on melting processes where no mechanical operation is required for the fuse to operate under fault conditions. a short fuse Bits of glass fused in a kiln; atomic nuclei that are fused together inside the stars. Some manufacturers of medium-voltage distribution fuses combine the overcurrent protection characteristics of the fusible element with the flexibility of relay protection by adding a pyrotechnic device to the fuse operated by external protective relays. Electrical Fuse is although an old protective device but still in use due to its high operating time. [12], Edison base (left) and Type S fuses (right), An older fuse box of the type used in North America, Some companies manufacture resettable miniature thermal circuit breakers, which screw into a fuse socket. IEC and UL nomenclature varies slightly. The IEC standard unifies several national standards, thereby improving the interchangeability of fuses in international trade. electrical fuse - an electrical device that can interrupt the flow of electrical current when it is overloaded.

So-called self-resetting fuses use a thermoplastic conductive element known as a polymeric positive temperature coefficient (PPTC) thermistor that impedes the circuit during an overcurrent condition (by increasing device resistance). There are many types of fuses, but the function of all these fuses is the same. It contains a piece of wire... | Meaning, pronunciation, translations and examples … Fuses only sense overcurrent, or to a degree, over-temperature, and cannot usually be used independently with protective relaying to provide more advanced protective functions, for example, ground fault detection. When too much current flows through the low resistance element of the fuse, the element melts and breaks the circuit. testing to be “Listed”. In medium-voltage distribution systems, a power fuse may be used to protect a transformer serving 1–3 houses. The International Electrotechnical Commission publishes standard 60269 for low-voltage power fuses. Such fuses can only be used outdoors. To unite as if by melting together; blend. Fuse is defined as to join together to form one, especially when joined by intense heat. Apart from protecting equipment, they are also used as safety measures to prevent any safety hazards to humans. See fuze. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. Fuse definition, a tube, cord, or the like, filled or saturated with combustible matter, for igniting an explosive. The blown fuse must be replaced with a new device which is less convenient than simply resetting a breaker and therefore likely to discourage people from ignoring faults. Fuse is defined as to join together to form one, especially when joined by intense heat. The characteristics of the limiter are matched to the size of cable so that the limiter clears a fault before the cable insulation is damaged. When you weld two pieces of metal together using a torch, this is an example of when you fuse.

This article, we discuss Electrical Fuse, Types of Fuses, Construction, Operation, Working and … fuze definition: 1. a string or piece of paper connected to a firework or other explosive that is used for lighting…. The resistance of the element generates heat due to the current flow. High rupture capacity fuses may be rated to interrupt current of 120 kA. Learn what these markings mean. The design does not allow for fitting of RCDs or RCBOs. Fuses are used on power systems up to 115,000 volts AC. to the existing carrier. Fuse elements may be supported by steel or nichrome wires, so that no strain is placed on the element, but a spring may be included to increase the speed of parting of the element fragments. A safety device that protects an electric circuit from excessive current, consisting of or containing a metal element that melts when current exceeds a specific amperage, thereby opening the circuit. To become physically joined together, as by melting. In the UK, older electrical consumer units (also called fuse boxes) are fitted either with semi-enclosed (rewirable) fuses (BS 3036) or cartridge fuses (BS 1361). While in this state, the breaker is effectively useless: it does not provide any overcurrent protection.[15]. a fuze which is ignited by heat or a spark produced by an electric current. (The spelling FUSE may also be met for this term, but FUZE is the preferred spelling in this context.) Their function is to provide protection of discrete components, or of complete circuits, by reliably melting under current overload conditions. SINCE 1828. Information and translations of FUSE in the most comprehensive dictionary definitions resource on the web. The exact fusing current is not as well controlled as an enclosed fuse, and it is extremely important to use the correct diameter and material when replacing the fuse wire, and for these reasons these fuses are slowly falling from favour. The energy is mainly dependent on current and time for fuses as well as the available fault level and system voltage. Circuit breaker fuses are designed as permanent replacements for Type T fuses; there are no Type S circuit breaker fuses. For example, a glass tube fuse rated at 32 volts would not reliably interrupt current from a voltage source of 120 or 230 V. If a 32 V fuse attempts to interrupt the 120 or 230 V source, an arc may result. To unite (atomic nuclei) in the process of. These devices are often used in aerospace/nuclear applications where replacement is difficult, or on a computer motherboard so that a shorted mouse or keyboard does not cause motherboard damage. en.wiktionary.org. Not only protect the high value electrical/electronic device and also to protect human being to use this device. In the UK, older electrical consumer units (also called fuse boxes) are fitted either with semi-enclosed (rewirable) fuses (BS 3036) or cartridge fuses (BS 1361). Electrical power and choosing fuses. Rated voltage should be higher than the maximum voltage source it would have to disconnect. (Fuse wire is commonly supplied to consumers as short lengths of 5 A-, 15 A- and 30 A-rated wire wound on a piece of cardboard.) The manufacturer may specify the voltage drop across the fuse at rated current. Fuse definition: A fuse is a safety device in an electric plug or circuit. The fuse element may be surrounded by air, or by materials intended to speed the quenching of the arc. Swe-Check sells fuses and circuit protection products. It is a deliberate weak link in a circuit which will 'blow' if an electrical appliance or extension lead draws too much current due to either an overload or a fault. See more. fuse noun /fjuːz/ /fjuːz/ Idioms. Fuse packages may include a rejection feature such as a pin, slot, or tab, which prevents interchange of otherwise similar appearing fuses. Some manufacturers have tested their fuses for up to 63 kA short-circuit current. [16]. The fuse is arranged in series to carry all the current passing through the protected circuit. Renewable fuses (rewirable or cartridge) allow user replacement, but this can be hazardous as it is easy to put a higher-rated or double fuse element (link or wire) into the holder (overfusing), or simply fitting it with copper wire or even a totally different type of conducting object (coins, hairpins, paper clips, nails, etc.) To receive news and special offers, please register here. The fuse in a plug is a safety device designed to protect the lead rather than the appliance. If you have additional comments or suggestions, please contact us at belcoelectric@gmail.com or call us directly at 305-801-9293. The fuse wire in an electrical fuse is selected in such a way that it does not face any damage when the normally stipulated amount of current flows through the circuit. AC Fuse : The AC fuses are classified into 2 varieties they’re the low voltage fuses and therefore the high voltage fuses. Element window — a small window built into the fuse body to provide visual indication of a blown element. Surface mount fuses have solder pads instead of leads. To liquefy or reduce to a plastic state by heating; melt. UL 248 currently has 19 "parts". The operating time is not a fixed interval but decreases as the current increases. Fuses designed for soldering to a printed circuit board have radial or axial wire leads. Oliver Hogg states the following about fuze: The word "fuze" is often spelt "fuse" by … It contains a piece of wire which melts when there is a fault so that the flow of electricity stops. Definition of fuse noun from the Oxford Advanced Learner's Dictionary. Electrical Fuse is a Protective Device that Interrupts Power Supply in case of Short Circuit. A safety device that protects an electric circuit from becoming overloaded. The melted fuse breaks the circuit, disconnecting the faulty circuit and keeping you safe. The fastest blowing fuses are designed for the most sensitive electrical equipment, where even a short exposure to an overload current could be damaging. A time-delay fuse (also known as an anti-surge or slow-blow fuse) is designed to allow a current which is above the rated value of the fuse to flow for a short period of time without the fuse blowing. jump to other results. Fuse definition is - to reduce to a liquid or plastic state by heat. fuse fuze. Breguet recommended the use of reduced-section conductors to protect telegraph stations from lightning strikes; by melting, the smaller wires would protect apparatus and wiring inside the building. A cartridge fuse found in amperage sizes 60amp or lower. If you have a fuse box, you will see a series of circular knobs. High-voltage fuses are used to protect instrument transformers used for electricity metering, or for small power transformers where the expense of a circuit breaker is not warranted. We use cookies and similar technologies to provide website functionality and traffic analysis. A circuit breaker at 115 kV may cost up to five times as much as a set of power fuses, so the resulting saving can be tens of thousands of dollars. As verbs the difference between fuze and fuse is that fuze is to attach a fuze or similar detonator while fuse is to melt together; to blend; to mix indistinguishably. If you are asked for a cartridge safety switch, it refers to a 60 or 30amp switch. 4248.11-07 (R2012); and, NMX-J-009/4248/11-ANCE). For coordination of fuse operation with upstream or downstream devices, both melting I2t and clearing I2t are specified. A fuse is an automatic disconnection of supply which is frequently shortened to … To melt something, such as metal or glass, by heating. External trip indicator — similar function to striker pin, but can be externally attached (using clips) to a compatible fuse. Circuit Breaker Fuses . Information and translations of FUSE in the most comprehensive dictionary definitions resource on … Definition of electrical fuse in the Definitions.net dictionary. Blade type. For example, bottle style fuses distinguish between ratings with different cap diameters. The power of an electrical appliance can be calculated from the current. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. The definition of a fuse is an electrical safety device that can stop current from flowing if it becomes overloaded, or a device that is used to ignite an explosive device. See more. Fuses for high-voltage equipment, up to 115,000 volts, are rated by the total apparent power (megavolt-amperes, MVA) of the fault level on the circuit. For example, fuse holders for North American class RK fuses have a pin that prevents installation of similar-appearing class H fuses, which have a much lower breaking capacity and a solid blade terminal that lacks the slot of the RK type. that flows through it and the potential difference. 40 synonyms of fuse from the Merriam-Webster Thesaurus, plus 48 related words, definitions, and antonyms. It contains a piece of wire which melts when there is a fault so that the flow of electricity stops. circuit breaker, breaker - a device that trips like a switch and opens the circuit when overloaded. Same basic definition applies to medium voltage fuses. A cord of readily combustible material that is lighted at one end to carry a flame along its length to detonate an explosive at the other end. Some vehicles use a dual 12/42 V DC electrical system[10] that will require a fuse rated at 58 V DC. These circular knobs can "blow" and cause power outages.
