Abstract
A circuit breaker is configured to provide both AC and DC protected power. The circuit breaker is packaged in a housing that includes a tripping module, a DC power supply, an AC load terminal, and a DC load terminal. The tripping module senses and responds to electrical faults by interrupting power, and the DC power supply converts received AC power to DC power. In some embodiments, the circuit breaker may be configured as a main breaker of a circuit breaker panel, while in other embodiments the circuit breaker may be configured as a branch circuit breaker that occupies a single branch circuit breaker mounting location in a circuit breaker panel. Methods of assembling a circuit breaker are also provided, as are other aspects.
