Bussmann makes the ATC that also complies with the same ISO 8820-3 and SAE J1284 standards. Regular (APR / ATC / ATO / ATS) blade-type fuses, also known as standard, were developed in 1976 as ATO by Littelfuse for low voltage use in motor vehicles.The mini fuses were developed in the 1990s. Unofficially, the "low-profile mini" fuse is sometimes incorrectly called "Micro" since the term means smaller than mini, but recently fuses using the Micro name have been released. LP-mini (APS), also known as low-profile mini.These types of fuses come in six different physical dimensions: Other common usage is in equipment with comparatively simple, low voltage DC electrical systems such as towed campers and marine applications such as sailboats and motor boats (typically smaller cabin cruisers).Įach fuse is printed with the rated current in amperes on the top. There may be a fuse for ignition off draw (IOD), which controls the drawing of electric current in a vehicle while it is shut off removing this fuse while the vehicle is shut off for more than a few weeks will prevent excessive depletion of the battery.īlade type Blade type fuses come in six physical sizes: Micro2, Micro3, low-profile (LP) Mini, Mini, Regular, Maxiīlade fuses (also called spade or plug-in fuses), with a plastic body and two prongs that fit into sockets, are mostly used in automobiles. They also exist as circuit breakers that are resettable using a switch. Some fuses or circuit breakers may nonetheless be placed elsewhere, such as near the cabin fan or air bag controller. Automotive fuses are typically housed inside one or more fuse boxes (also called an integrated power module (IPM)) within the vehicle, typically on one side of the engine compartment and/or under the dash near the steering wheel. They are occasionally used in non-automotive electrical products. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. Automobile electrical circuit breaker with resettable switchĪutomotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. The top metal surfaces can be tested using multimeter probes. Mini / Regular / Maxi blade-type automotive fuses, side and top views.
