Schneider Electric's MasterPact NW20H2 is a 2,000 A, four‑pole drawout low‑voltage circuit breaker in the NW family, designed for use as main protection in large switchgear. It is shipped as a "no controls" unit, i.e., without a trip/control module, and configured with a right‑hand neutral for NW20H installations. The breaker is rated for 440 VAC at 50/60 Hz and offers an ultimate breaking capacity of 100 kA (Icu) at 440 VAC. In some markets, the NW20H2 frame has been listed as discontinued after 2025 and superseded by LV948438.
