- Description
The Schneider Electric LV429492 is a VigiPacT earth-leakage add-on module for 3-pole ComPacT/ComPact NSX250 circuit breakers, rated 200 to 440 V AC. It mounts directly on the breaker terminals, is self-powered from the distribution-system voltage even on 2 phases, and directly actuates the breaker's trip unit when the earth-leakage sensitivity, adjustable from 30 mA to 30 A, is exceeded.

Selection Notes
This is the 3-pole version sized for the NSX250 frame only; the NSX100/160 and NSX400/630 frames each use their own dedicated add-on since the module's mechanical interface is frame-specific. The dual class A/AC sensitivity range in one module covers both standard AC earth faults (class AC, 10-30 A) and pulsating DC faults from rectified loads (class A, down to 30 mA) without a separate sensor.
