ATM, ATC, MAX & Glass Tube Footprint Circuit Breakers

Automotive Circuit Breakers

Bussmann offers a large selection of automotive circuit breakers including both OEM-style and fuse-replacement devices.
Circuit breakers are available with three types of reset after an overcurrent event.

NOTE: Always follow the OEM's recommendations when replacing circuit breakers. Replace only with the same reset type and amp rating for aftermarket applications.

Type I - Automatic Reset

Type I circuit breakers automatically reset after opening. If the fault or overcurrent condition still exists, the breaker will continue to cycle between ON and OFF positions until the overcurrent problem is corrected. These devices are sometimes called "cycling breakers." Type I/Automatic Reset circuit breakers do not address, or correct, overcurrent or fault conditions. They only react by cycling OFF and ON. Any overcurrent or fault condition that causes a Type I circuit breaker to operate should be corrected as soon as possible. Continued vehicle operation with an overcurrent or fault condition (causing the Type I circuit breaker to cycle) is NOT recommended.

Type II - Modified Reset

Type II circuit breakers will remain “tripped” by an internal resistor (in the OFF position) as long as the circuit is powered. Type II breakers can be reset by turning the circuit off, or by turning the ignition switch to the OFF position. These devices are sometimes called "non-cycling breakers."
Type III - Manual Reset
Type III circuit breakers will remain tripped (in the OFF position) until an indicator button or lever is manually reset. Some Type III breakers are available with a switch feature that allows the use of an external button to de-energize the circuit.

Blade-Type Breakers

Bussmann blade-type circuit breakers are available for ATM, ATC and MAXI fuse footprints in reset modes that correspond to SAE categories: SAE Type I (automatic reset), SAE Type II (modified reset) and SAE Type III (manual reset).

High Amp Circuit Breakers

High amp circuit breakers are available for automotive and marine applications in Type I and Type III reset modes. Typically used in auxiliary and accessory circuits for trucks, busses, RVs and boats, they are available in weatherproof/waterproof panel and flush mount versions. They can also be used in battery charging systems that use battery isolators to manage and protect batteries in multi-battery installations.

ATM Footprint Breakers

Type I CB211 and Type II CB212

Type I CB211 and Type II CB212 circuit breakers match the ATM fuse footprint.

Ultra-thin, to fit in tight spaces, they're the smallest automotive circuit breakers on the market and comply with SAE standard J553.
