Shunt Trip Coil

A shunt trip coil is an optional accessory in a circuit breaker that mechanically trips the breaker when power is applied to the shunt trip terminals.

The power for the shunt trip does not come from within the breaker, so it must be supplied from an external source.

Its most common application is when we need to control switching off the power of a panel by a feedback signal from the BMS system.
