LV429488

The Schneider Electric LV429488 is an Earth‑leakage add‑on protection module (also known as a VigiPacT add‑on module) for use with ComPacT NSX 100 and NSX 160 molded case circuit breakers. It provides residual (earth) current protection by detecting leakage currents and directly actuating the breaker’s trip function when a fault occurs.
