This pre-wired MX shunt trip is used on Compact NSXm and PowerPact B devices. This auxiliary is used for emergency off or failsafe remote opening applications. It is a one click spring type auxiliary for quick and easy installation, visible from the front face of the device. This MX auxiliary has a 220/240VAC 50Hz, 208/240/277VAC 60Hz or 250VDC rated voltage. It trips the circuit breaker when the control voltage rises above 70% of its rated value. It complies with IEC 60947-2 standard. Compact NSXm and PowerPact B embed either 1 MN or 1 MX coil.
