Trip Closing Coil is the releasing component of circuit breakers that switch large currents in energy distribution. It is their responsibility to interrupt fault currents/voltages in order to prevent harm to downstream systems. This separation mechanism is started by the trip coil triggering solenoid. This is very easy to install and simple to operate. Trip Closing Coilis an optional circuit breaker device that adds further protection to your system. The close coil is a solenoid that controls the circuit breaker's close latch and allows for remote shutting.
