Schneider C25F32D250 ComPacT NSX250F Trip Unit 3P 250 A MicroLogic 2

The Schneider Electric C25F32D250 is a ComPacT NSX250F 3-pole molded case circuit breaker rated at 250 A, equipped with an integrated Micrologic 2.2 electronic protection unit. Designed for electrical power distribution, it achieves an ultimate short-circuit breaking capacity (Icu) of 36 kA at 380/415 V AC per IEC 60947-2. The fixed-mounted unit provides LSoI protection: long-time overload, short-time delayed short-circuit, and instantaneous short-circuit.
