Automotive Circuit Breakers

Cooper Bussmann offers the industry's largest selection of automotive

circuit breakers including both OEM-style and fuse-replacement devices.

Circuit breakers are designed to offer a variety of performance

characteristics including three types of reset.

(NOTE: Always follow the OEM's recommendations when replacing circuit

breakers. Replace only with the same type breaker in aftermarket

applications.)

Type I - Automatic Reset

Circuit breaker automatically resets after opening. If the fault still exists, the

breaker will continue to cycle between ON and OFF positions until the

overload 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 any Type I circuit breaker

to operate should be corrected as soon as possible. Continual vehicle

operation under an overcurrent or fault condition (causing the Type I circuit

breaker to cycle) is NOT recommended.

Type II - Modified Reset

The circuit breaker will remain tripped (in the OFF position) as long as

there's power to the circuit, due to an internal resistor. Type II breakers can

be reset by turning off the circuit, or by turning off the ignition switch. These

devices are sometimes called "non-cycling breakers." Several Cooper

Bussmann Type II breakers feature silver-colored bodies.

Type III - Manual Reset

The circuit breaker will remain tripped (in the OFF position) until an indicator

button or lever is manually reset. Type III breakers are also available with a

switchable feature, which allows you to use an external button to disable the

circuit. Cooper Bussmann circuit breakers feature our patented fail-safe

technology - offering an innovative element design which combines the

resetable performance of circuit breakers with the short-circuit protection of

a fuse.

• Resetable, to work like a normal "cycling" breaker, in low overload

conditions.

• Under severe overload or short-circuit conditions, the breaker's element

will open to prevent damage to the circuit.

Blade-Type Breakers

Cooper Bussmann blade-type circuit breakers are available in several reset

modes that correspond to SAE categories: SAE Type I (automatic reset), SAE

Type II (modified reset) and SAE Type III (manual reset). All Cooper

Bussmann blade-type circuit breakers utilize carefully designed and

manufactured snap-acting thermal elements with precious metal electrical

contacts.

ATM Footprint Breakers

CB211 and CB212 Cooper Bussmann ATM footprint breakers match the

blade footprint of ATM fuses. Ultra-thin, to fit in tight spaces - they're the

smallest automotive circuit breakers on the market. Cooper Bussmann ATM

footprint breakers comply with SAE standard J553.

Mini Devices

Transorb, resistor and diode vehicle-style electrical protection devices easily

install in common ATM fuse holders. These circuit protection devices provide

voltage and current limiting functionality to

vehicle circuitry; and are designed for the

on- and off-highway requirements of heavy

trucks, RV, construction, agriculture, ATV and

material handling equipment.

• Transorb - Protects against voltage

spikes. Clamp rating: 27Vdc.

Power rating: 1500W

• Resistor - Drops circuit voltage.

Power rating: 5W. Resistance: 68Ω.

• Diode - Prevents reverse current flow. Amp rating: 6A.
