![]() Fuseholders for cartridge fuses can be inline fuse holder, fuse clips, panel mount fuse holder. There are other types of fuses like SMD fuses, axial fuses, thermal Fuses, HRC fuse etc.įiltering more, for DIY works, you need to know only about the cartridge fuses, axial fuses and their fuseholders. Cartridge fuses typically a fuse wire enclosed inside a glass/plastic tube. But their form factor prevents to use them inside smaller compact panels where typically cartridge fuses are used. Obviously they are cheap at long run, convenient, heavy duty. They are usually made of ceramic with metal contacts and uses fuse wire. Types of Fuses, Fuseholders Used in DIY & HouseholdĪfter our so much filtering of types, remaining is ceramic fuses which are officially named semi-enclosed rewirable fuse (SERF). Interrupting rating (Breaking capacity).Time-current characteristic (fuse speed).Fuse, fuse holder, fuse wire have these parameters written – There are lot of complicated standards and confusions with fuses in industrial usage. In other words, we will not discuss about circuit breaker, thermal cutoff, resettable fuse, automotive fuses and rarely which types someone unlikely to face for DIY and household – we are towards the fuses which follows I square T equation. In this article we will only discuss about the types of fuses, fuseholders used in DIY & household electrical and electronics. There are complicated fuses in electronics and electrical like used inside the refrigerators. We commonly see “one time use” fuse, there is no actual with no AC, DC matter – they are simply a wire which follows the I square T equation and gets blown away upon crossing a given load. Obviously anything on this earth related to electrical can be divided in to : Thermal cutoffs are commonly found at the bottom of household things which has motors like food processor, washing machine, mixer grinder – a red coloured plastic rod becomes elongated upon overload. Resettable fuses are not the thing one may imagine from name – it is not the type with fuse wire. There are similar things like fuse named thermal cutoff, resettable fuse etc. Thomas Edison mentioned circuit breaker too in his patents. Circuit breakers commonly used now in apartments, households which essentially looks like a switch and automatically cuts off the power supply to circuit upon short circuit, overload. There is another similar thing named circuit breaker. Who discovered fuse that is not known, he added a standard and Louis Breguet recommended such thing in mid 1850. Thomas Edison has not discovered fuse too. Thomas Edison never discovered incandescent bulb but he discovered the Edison screw mount and modified filament. Fuse provides overcurrent protection to a circuit using basic theory. The second most common size is the 20mm x 5mm model.Thomas Edison has patent on fuse. The 6mm x 30mm is by far the most common and found in everything from automobiles to household electronic devices. Glass Fuse Size OptionsĮlectronic devices typically use one of two standard sizes of fuses. The basic concept of using a fusible link-which self-heats due to current flow and then opens to cut off current flow if there is an overcurrent condition: it is simple, reliable, clear cut, and unambiguous. The 3AG designation stands for automotive applications and reflects its original design as an automotive fuse in the 1930's.įuses are an essential part of many system designs, and we’ve come to depend on them since the earliest days of electricity. The 3AG fuse dimensions are 1 1/4-inch long by 1/4-inch (30mm x 6mm) in diameter. The 3AG cartridge fuse is one of the most popular fuses available.
