A circuit breaker is a type of switch designed to disrupt electrical current when an overload or short occurs. Most dc circuit breaker options are thermally controlled, meaning during an over current condition, the additional current will cause excess heat to build up in the circuit breaker. With this excess heat, the breaker will trip, making it an essential safety component providing thermal overload protection to diverse applications including, marine, automotive, ambulance fire equipment, portable generators, and other electrical applications. Listed below are all the types of circuit breakers Del City offers. Characteristics differ with each offering, but all are single pole. The different characteristics of each of the types of circuit breakers provide you with different benefits for different applications that require DC circuit breakers.
