Schneider Electric LV426844 ComPacT NSXm MX Shunt Trip Release 220-240 V AC Circuit Breaker Accessory

The Schneider Electric LV426844 is a standard 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

LV426844 suits ComPacT NSXm and PowerPact B breakers wired to 220-240 V AC 50 Hz control circuits; the same body also covers 208-240 V AC 60 Hz, 277 V AC 60 Hz and 250 V DC supplies. For breakers running on 380/415 V AC or 440/480 V AC control circuits, choose the higher-voltage shunt trip variant instead. The one-click spring-terminal body mounts on the breaker's front face, so wiring the emergency-off or remote-opening circuit needs no screw tools and the coil position stays visible for inspection. ComPacT NSXm and PowerPact B accept either one MX or one MN coil, never both at once.
