Product details

Overview

The C25W4TM250 is a Schneider ComPacT NSX molded case circuit breaker rated 250 A at 40 °C with a 100 kA Icu breaking capacity at 690 V AC, built on a 4-pole frame with a thermal-magnetic TM-D trip unit. It is a fixed-mount, toggle-control device compliant with EN/IEC 60947-2, suited for distribution applications requiring high fault-current interruption in a compact 140 mm wide footprint.

The C25W4TM250 is in active production as a current ComPacT NSX catalogue item; standard lead time applies and an RFQ confirms availability for line-down or BOM-fill orders.
