20 Amp Three-Pole Type QP Circuit Breaker with 120-Volt Shunt Trip

Shunt trip breakers operate with the same functionality of a standard type breaker providing over current and short circuit protection, as well as switching capability. The Shunt trip breakers provide an additional function in that it can be tripped remotely through the use of a built in magnetic coil that can be energized to trip the breaker. Each Shunt trip breaker will have an additional 1 in. pole attached to it to house the magnetic coil. The additional pole does not plug onto and is not energized by the bus bar.
