Definition of FUSE in the Definitions.net dictionary. When too much current flows through the low resistance element of the fuse, the element melts and breaks the circuit. Fuze Fuze (? Information and translations of FUSE in the most comprehensive dictionary definitions resource on the web. These are still used in consumer units in some parts of the world, but are becoming less common. testing to be “Listed”. 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). Swe-Check: The Circuit Protection Specialists. 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. Some varieties of HRC fuse include special handling features. 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. To equip with a mechanical or electrical fuse. There are several different types of automotive fuses and their usage is dependent upon the specific application, voltage, and current demands of the electrical circuit. , A fuse was patented by Thomas Edison in 1890 as part of his electric distribution system.. Fuses are designed to have particular characteristics of operating time compared to current. Such fuses can only be used outdoors. . Filling a fuse body with sand provides additional cooling of the arc and increases the breaking capacity of the fuse. Some fuses for medium-voltage applications use two or three separate barrels and two or three fuse elements in parallel. If you don't see a series of switches when you open your electrical panel, you may have a fuse box. Thermal fuses are a 'one shot', non-resettable device which must be replaced once they have been activated (blown). Automotive fuses are used to protect the wiring and electrical equipment for vehicles.

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. Definition of FUSE in the Definitions.net dictionary. The fastest blowing fuses are designed for the most sensitive electrical equipment, where even a short exposure to an overload current could be damaging. The family of # articles includes igniters, cartridges, both explosive and shaped charges, cutters, detonators, fireworks, flares, fuse, fuzes, grenades, igniters, primers, release devices and signals of all types. When talking about being laid off, he has a short fuse. If you have a fuse box, you will see a series of circular knobs. Standards for automotive fuses are published by SAE International (formerly known as the Society of Automotive Engineers). It contains a piece of wire which melts when there is a fault so that the flow of electricity stops. Swe-Check sells fuses and circuit protection products. If you have additional comments or suggestions, please contact us at firstname.lastname@example.org or call us directly at 305-801-9293. 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. While in this state, the breaker is effectively useless: it does not provide any overcurrent protection.. It contains a piece of wire... | Meaning, pronunciation, translations and examples See more. Automotive glass fuses were made in different lengths, to prevent high-rated fuses being installed in a circuit intended for a lower rating. Electrical Fuse The fuse is a device used in an electrical circuit for protecting electrical devices against overloads and short circuit. SINCE 1828. 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. There are many types of fuses, but the function of all these fuses is the same. What does fuse mean? Swe-Check: The Circuit Protection Specialists. 1 fuse / ˈ ... also US fuze: a mechanical or electrical device that causes a weapon (such as a bomb or torpedo) to explode. 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. Surface-mount technology "chip type" fuses feature few or no markings, making identification very difficult. July 16, 2018 Comments Off on Fuse definition News Like. They are occasionally used in non-automotive electrical products. (Fuse wire is commonly supplied to consumers as short lengths of 5A-, 15A- and 30A-rated wire wound on a piece of cardboard.) Fuse is the less expensive, effective, simple and high degree of safety device in circuit protection. If you are asked for a cartridge safety switch, it refers to a 60 or 30amp switch. The energy is mainly dependent on current and time for fuses as well as the available fault level and system voltage. to the existing carrier. These Edison base fuses would screw into a fuse socket similar to Edison-base incandescent lamps. A maximum current that the fuse can continuously conduct without interrupting the circuit. GAMES BROWSE THESAURUS WORD OF THE DAY WORDS AT PLAY. The IEC standard unifies several national standards, thereby improving the interchangeability of fuses in international trade. 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. 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. Definitions of electrical fuse, synonyms, antonyms, derivatives of electrical fuse, analogical dictionary of electrical fuse (English) ... fuse, fusee, fuze, fuzee, primer, priming - electrical fuse, fuse, safety fuse [Dérivé] deactivate, defuse [Ant.] The fuse element is made of zinc, copper, silver, aluminum, or alloys among these or other various metals to provide stable and predictable characteristics. When the surrounding temperature gets too high, the composition melts and allows the spring contact mechanism to break the circuit. It is used, for example, in networks where multiple cables may be used in parallel. Fuses consist of a low-resistance metal or wire that is used to close a circuit. This should be higher than the prospective short-circuit current. The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices. Upgrading Your Electrical Service . Glass cartridge and plug fuses allow direct inspection of the fusible element. Indicating disc — a coloured disc (flush mounted in the end cap of the fuse) falls out when the element is blown. Another word for fuse. These fuses are intended for installations following Canadian Electrical Code, Part I (CEC), or the National Electrical Code, NFPA 70 (NEC). Special current-limiting fuses are applied ahead of some molded-case breakers to protect the breakers in low-voltage power circuits with high short-circuit levels. cartridge fuse - a fuse cased in a tube. Fuses can be designed and manufactured to higher standards than the minimum standards required to pass U.L. 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. 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. Ceramic fuses have the advantage of a higher breaking capacity, facilitating their use in circuits with higher current and voltage. Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s). Fuse is defined as to join together to form one, especially when joined by intense heat. A standard fuse may require twice its rated current to open in one second, a fast-blow fuse may require twice its rated current to blow in 0.1 seconds, and a slow-blow fuse may require twice its rated current for tens of seconds to blow. For example, bottle style fuses distinguish between ratings with different cap diameters. High voltage expulsion fuses surround the fusible link with gas-evolving substances, such as boric acid. fuse /fjuːz/ Definitions. To become physically joined together, as by melting.
