A Shunt Trip coil is used to remotely trip a circuit breaker and some switch disconnectors.

Schneider Electric uses the abbreviation MX or iMX for Shunt Trip coils.

A Shunt Trip coil has to have a voltage applied to it to trip the device.

An example of an application for a Shunt Trip would be for load shedding.
A second example would be for an EPO circuit with N/O EPO contacts wired in parallel.
