Abstract

A circuit breaker having a trip mechanism and an electronic module having an application specific integrated circuit (ASIC), a control circuit, a composite circuit which generates a composite signal voltage, a residual circuit, the circuit breaker comprising a first power supply to provide a first voltage signal and a second power supply to provide a second voltage signal. An analog override circuit in the circuit breaker is configured to receive the first voltage signal from the first power supply, the second voltage signal from the second power supply and the composite signal voltage from the composite circuit. The analog override circuit provides an override signal to the ASIC which is coupled to a logic gate configured to receive a first trip signal from the control circuit and a second trip signal from the ASIC and provides a third trip signal to the trip mechanism.
