Circuit breakers — general information

Circuit breakers are commonly used to protect vehicle electrical components such as headlights and power window motors, door lock actuators, etc.

Some breakers reset automatically after tripping. If the overload that caused the tripping of the breaker was not episodic, the condition of the corresponding circuit should be checked without delay. After the fault has been cleared, the circuit breaker will return to normal operation. Sometimes the interrupter must be reset manually after the cause of the overload has been eliminated.
