What is shunt trip?

Shunt trip is an electrical component used in circuit breakers or disconnect switches to remotely trip the device from a control system or switch. It is mainly used in cases of emergency where a quick and safe shutdown is necessary. In shunt trip, a coil is energized by a voltage source, which creates a magnetic field that opens the circuit breaker or disconnect switch. It is often used in industrial and commercial settings where safety is of utmost importance. These are often used in elevators, escalators, and critical machinery where quick shutting down of power is important.
