The electric operating mechanism is designed for remote or automatic control of circuit breakers. It allows the breaker to be opened or closed electrically, providing convenience for centralized control, automation systems, and enhanced safety in power distribution.
The shunt release is an accessory for circuit breakers that enables remote tripping. When it receives a control signal (voltage pulse), it immediately trips the breaker, cutting off the circuit. It is commonly used for emergency shutdowns, fire alarm systems, and remote protection.
