Product details

Overview

The C25N44V250 is a Schneider ComPacT NSX molded case circuit breaker with 4 poles, rated 250 A at 40 °C, and a breaking capacity of 90 kA at 440 V AC. It carries the MicroLogic 4.2 electronic trip unit offering L, So, I, and R protection profiles for distribution applications. The unit is in active production and readily sourced through standard distribution channels.

Schneider lists the C25N44V250 as an active, current-production part within the ComPacT NSX range. For procurement, an RFQ is the fastest path to confirm lead time and quantity; the part is available through standard distribution with typical lead times varying by region and order volume.
