Switchgear Protection and Dashpot Trips for Circuit Protection

What is a Shunt Trip Device and how does it work in a circuit breaker? Shunt trips for breakers add safety by shutting down electric power in emergencies. They avoid equipment damage and personal injury.

During power surges, the overload charges an electromagnet to trip a switch and stop the electrical connection and shut down power. Shunt trip breakers have an exterior power source.
