More about shunt trip
A shunt trip device 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. Some circuit breakers allow field installlation of a shunt trip kit, however others require factory installation when the breaker is ordered. Check the specific breaker type for available ac and dc shunt trip voltage ratings and for the method of installation.
A "shunt trip" coil is installed in a circuit breaker to provide remote trip of the breaker but "undervoltage" or "no voltage" coil is installed to provide automatic tripping when loss of power occurs or when there is a major voltage dip.
