Abstract
A circuit breaker apparatus may be used to interrupt overcurrent and ground fault in a circuit. The circuit breaker apparatus may include an overcurrent coil for tripping the circuit breaker apparatus, a voltage coil also for tripping the circuit breaker apparatus located proximate to the overcurrent coil, and ground fault electronics connected to the voltage coil and structured to detect a ground fault in the circuit when the ground fault exceeds a threshold level. The ground fault electronics can be structured to send a trip signal to the voltage coil when a ground fault is detected, and the voltage coil can be structured to trip the circuit breaker apparatus when it receives the trip signal from the ground fault electronics.
