across it. The PPTC thermistor is self-resetting in that when current is removed, the device will cool and revert to low resistance. Fuses consist of a low-resistance metal or wire that is used to close a circuit. Cartridge fuse carriers are also now available for DIN-rail enclosures. Fuses contain a length of thin wire (usually of a metal alloy) that melts and breaks the circuit if too much current flows through it. Automotive fuses can be mounted in fuse blocks, inline fuse holders, or fuse clips. The general requirements (248-1) apply except as modified by the supplemental part (240-x). Existing Edison fuse boards can easily be converted to only accept Rejection Base (Type S) fuses, by screwing-in a tamper-proof adapter. High rupturing capacity fuses can be rated to safely interrupt up to 300,000 amperes at 600 V AC. Short circuits, overloading, mismatched loads, or device failure are the prime or some of the reasons for fuse operation. Fuses for small, low-voltage, usually residential, wiring systems are commonly rated, in North American practice, to interrupt 10,000 amperes. The voltage drop should be taken into account, particularly when using a fuse in low-voltage applications. 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). Most fuses feature some kind of markings on the caps or label. It may be installed in a circuit-breaker box with a door. 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. 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. Swe-Check sells fuses and circuit protection products. translation and definition "fuse", Dictionary English-English online. In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Another word for fuse. Some automotive fuses are occasionally used in non-automotive electrical applications. The fuse blew as he pressed the button to start the motor. (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.) UL 248 currently has 19 "parts". 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. Large power fuses use fusible elements made of silver, copper or tin to provide stable and predictable performance. This article, we discuss Electrical Fuse, Types of Fuses, Construction, Operation, Working and … Fuse boxes are less common than breaker boxes, but still exist in some homes. Indicating disc — a coloured disc (flush mounted in the end cap of the fuse) falls out when the element is blown. Fuse definition: A fuse is a safety device in an electric plug or circuit. A fuse is a safety device in an electric plug or circuit. Ratings were 5, 10, 15, 20, 25, and 30 amperes. The fuse elements may be shaped to increase heating effect. ... plural fuses. The current-time characteristic of a fuse cannot always be correlated with that of the protective device. Ambient temperature will change a fuse's operational parameters. Once this device has functioned in an open circuit, it ought to rewire or changed based on the type of fuse. 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. A fuse is an electrical safety device built around a conductive strip that is designed to melt and separate in the event of excessive current. If there is a short or fault anywhere in the circuit, or the circuit is overloaded, the metal strip, or link, heats up and quickly melts, opening the circuit and shutting off the power. In large fuses, current may be divided between multiple strips of metal. What does FUSE mean? Fuses are designed to have particular characteristics of operating time compared to current. 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. The associated high pressure (often greater than 100 atmospheres) and cooling gases rapidly quench the resulting arc. UN-2. Silica sand or non-conducting liquids may be used. Meaning of electrical fuse. High voltage expulsion fuses surround the fusible link with gas-evolving substances, such as boric acid. If you are asked for a cartridge safety switch, it refers to a 60 or 30amp switch. 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. cartridge fuse - a fuse cased in a tube. fuse /fjuːz/ Definitions. Fuse boxes are found in old Eastern CT homes. It is used, for example, in networks where multiple cables may be used in parallel. To prevent installation of fuses with an excessive current rating, later fuse boxes included rejection features in the fuse-holder socket, commonly known as Rejection Base (Type S fuses) which have smaller diameters that vary depending on the rating of the fuse. Some manufacturers have tested their fuses for up to 63 kA short-circuit current. Make sure that the correct fuse is fitted. Couple reasons to use fuses. If you don't see a series of switches when you open your electrical panel, you may have a fuse box. Find more ways to say fuse, along with related words, antonyms and example phrases at Thesaurus.com, the world's most trusted free thesaurus. Automotive fuses are used to protect the wiring and electrical equipment for vehicles. The fuse is arranged in series to carry all the current passing through the protected circuit. The fuses to be considered are current sensitive devices designed to serve as the intentional weak link in the electrical circuit. A safety device placed in a circuit, consisting of a replaceable plug or tube containing wire or metal that will melt and break the circuit if the current exceeds a specified amperage. In the 1950s, fuses in new residential or industrial construction for branch circuit protection were superseded by low voltage circuit breakers. Some fuses for medium-voltage applications use two or three separate barrels and two or three fuse elements in parallel. contents of the two cells fuse together, cytoplasm ~ B, Copyright © 2020 LoveToKnow. 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. A fuse rated for 1 A at 25 °C may conduct up to 10% or 20% more current at −40 °C and may open at 80% of its rated value at 100 °C. 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. Definition of FUSE in the Definitions.net dictionary. ), n. A tube, filled with combustible matter, for exploding a shell, etc. See more.
