Schneider C25F3 ComPacT NSX250F Trip Unit 3P

The Schneider Electric C25F3 is the ComPacT NSX250F base frame, a 3-pole, 250 A bare chassis circuit breaker without a trip unit, designed for electrical power distribution. With an ultimate short-circuit breaking capacity of 36 kA at 380/415 V AC per IEC 60947-2, it forms the foundation for customized switchgear assemblies requiring a separately installed protection unit.
