Overview
The C40V42D250 is a Schneider ComPacT NSX molded case circuit breaker, 4-pole, rated 250 A at 40 °C with a MicroLogic 2.3 electronic trip unit. Its breaking capacity reaches 85 kA at 690 V AC, and it is designed for distribution applications in fixed-mount, toggle-control format. The part remains in active production.
Lifecycle & availability
Schneider lists the C40V42D250 as an active production item, so it is available through standard distribution channels without last-time-buy constraints. For a BOM freeze or line-down need, an RFQ is the fastest path to confirm current lead time and quantity. The breaker carries 12000 electrical cycles at 440 V In/2 and 15000 mechanical cycles, reflecting a mature, field-proven design.
