Circuit breakers — basic information

Circuit breakers are designed to protect certain components such as sunroof motors, power window motors and airbag circuit resistors.

In some models, the circuit breakers turn on automatically, that is, when an overload occurs in the protected circuit, the circuit breaker instantly de-energizes the circuit, and then closes it again. If the target does not turn on, check it immediately. After the circuit overload is eliminated, the circuit breaker must close the circuit again. Some breakers are manually activated.
