Schneider C40F32D400 ComPacT NSX400F Trip Unit 3P 400 A MicroLogic 2

The Schneider Electric C40F32D400 is a 3-pole ComPacT NSX400F moulded case circuit breaker (MCCB) equipped with the MicroLogic 2.3 electronic protection unit, rated 400 A at 40°C. Designed for electrical power distribution, it delivers an ultimate short-circuit breaking capacity (Icu) of 36 kA at 415 V AC and 40 kA at 240 V AC per IEC 60947-2, with a rated voltage of 690 V AC. The fixed-mounted, handle-operated breaker provides LSoI protection - long-time overload, short-time, and instantaneous short-circuit functions.
