Product details

Overview

The C25R42D250 is a Schneider ComPacT NSX molded case circuit breaker rated 250 A at 40 °C with 4 poles and a 200 kA breaking capacity (Icu) at 690 V AC. It carries a MicroLogic 2.2 electronic trip unit offering L, So, and I protection curves for distribution applications. The unit is fixed-mounted with a toggle control and remains in active production.

Schneider lists the C25R42D250 as an active part within the ComPacT NSX range. Sourcing is straightforward through standard distribution channels; an RFQ will confirm current lead time and quantity. For a BOM requiring this exact 4-pole, 250 A, 200 kA rating, no direct replacement is needed — the part is available new.
