Schneider Electric LV426864 ComPacT NSXm MX Pre-Wired Shunt Trip Release 220-240 V Circuit Breaker Accessory

The Schneider Electric LV426864 is a pre-wired MX shunt trip release for ComPacT NSXm and PowerPact B moulded case circuit breakers, rated 220-240 V AC 50 Hz (also available as 208-240 V AC 60 Hz, 277 V AC 60 Hz or 250 V DC on this same reference). It trips the breaker on command for emergency-off or remote-opening duty once the control voltage exceeds 70% of its rated value, with a response time under 50 ms.

Selection Notes

LV426864 is the pre-wired version of the ComPacT NSXm MX shunt trip, terminated with a 1 m factory cable instead of spring terminals, which saves field wiring time when the panel builder runs the emergency-off loop straight to a terminal block. It carries the same 220-240 V AC 50 Hz control rating as the standard LV426844 body (also covering 208-240 V AC 60 Hz, 277 V AC 60 Hz and 250 V DC). For 380/415 V AC or 440/480 V AC control circuits, use the higher-voltage variant instead.
