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 applica-
tions 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.
