Overview
The LV431533 is a Schneider Vigi MH earth-leakage add-on module for the ComPact NSX250 circuit breaker frame, rated 440 VAC and 250 A, with adjustable sensitivity from 0.03 A to 10 A across five settings and four time-delay options including 0 ms, 60 ms, 150 ms, and 310 ms. It is a 3-pole Class A device built to IEC 60947-2, designed for wiring applications where earth-leakage protection must be added to an existing ComPact NSX250 breaker without replacing the trip unit.
Schneider discontinued the LV431533 on 2022-02-07; no official successor is listed. For existing panels requiring this exact Vigi MH module, sourcing now runs through surplus and broker channels. An RFQ confirms current availability and lead time.
