MERLIN GERIN MX-A SHUNT TRIP RELEASE COIL

MERLIN GERIN MX-A is a shunt trip release coil for Merlin Gerin Masterpact low voltage air circuit breaker (ACB) series, later acquired by Schneider Electric. This shunt trip release coil is an auxiliary accessory for circuit breakers, which can remotely trip the main breaker when energized by external control signal. This shunt trip release coil is commonly available in AC or DC coil versions, compatible with Masterpact M series air circuit breakers. This shunt trip release coil is used for emergency remote tripping, fire safety interlock and automatic load shedding in power distribution systems.

This unit is a vital electrical spare part for land and marine low voltage switchgear overhaul. The electrical spare part receives fire alarm, generator protection or emergency shutdown command to cut off main power circuit. The electrical spare part works with breaker auxiliary contacts to send breaker status feedback signal to control panel. The electrical spare part can replace faulty coil assembly to restore remote electrical tripping function of air circuit breaker.

It delivers reliable remote emergency power tripping control for low voltage power distribution systems. The remote emergency power tripping control triggers breaker opening immediately once the coil is energized. The remote emergency power tripping control is widely used for fire safety, emergency shutdown and interlock protection. The remote emergency power tripping control isolates the faulty circuit to prevent further electrical damage in factory and marine power panels.

MERLIN GERIN MX-A shunt trip coil is fitted inside Masterpact M air circuit breaker compartment. It is discontinued original Merlin Gerin breaker accessory for LV switchgear.
