Automatically triggers a fault signal when tripped by overload, short circuit, or external release. Ideal for automation system integration.
Provides real-time remote status monitoring and interlocking by reversing contact states (NO+NC) during opening/closing operations.
Remotely trips the circuit breaker using electric current. Automatically cuts off the signal circuit after tripping.
