  • Circuit breakers are protective devices that function similarly to a fuse. Circuit breakers monitor the current flowing through them by means of a conductor and interrupt the electrical current or energy flow to an energy sink or a consumer, which is referred to as a trigger if protective parameters, such as current limit values or current time period limit values, i.e. if a current value is available for a certain period of time, are exceeded.
