16 CIRCUIT BREAKERS
Type I – Automatic Reset
Cycles or continuously resets until the fault is corrected.Type I circuit breakers
are typically used to protect circuits which occasionally experience momentary
overloads such as wiper motor and headlamp circuits where a self resetting
device is preferred.
Type II – Modified Reset
Non-cycling, remains in open position while there is power to the circuit. Resets
when ignition is turned off.Type II circuit breakers are typically used in applications where fuse replacement is objectionable, such as power window, seat
and sunroof circuits.
Type III – Manual Reset
Manually resettable circuit breakers remain in the open position until a button,
lever or other external reset device is manually depressed.Type III circuit
breakers are typically used in applications where a manual reset is desired for
safe diagnosis of a circuit fault.
