It carries a 150 kA Icu at 415 V AC (breaking capacity code L), with an Ics of 150 kA at 380/415 V AC, meaning it can repeatedly interrupt fault currents up to that level without needing replacement after a single event — a real advantage for high-fault locations like main switchboards or feeder breakers in industrial plants. Mounts fixed to a backplate (not DIN rail) — the 185 mm width, 255 mm height, and 110 mm depth fit standard ComPacT NSX cutouts. The toggle control and IP40 front face (IK07 impact resistance) suit enclosed panel installation where accidental contact is a concern. Rated insulation voltage 800 V AC, operational voltage 690 V AC. Electrical durability: 12,000 cycles at 440 V AC at In/2, 6,000 cycles at In. Mechanical durability 15,000 cycles. Class II insulation on the front face adds operator touch-safety.","metaTitle":"Schneider Electric C40L4 ComPacT NSX400L, 400A Frame, 150kA/","metaDescription":"Schneider Electric C40L4 ComPacT NSX400L basic frame, 400A at 40°C, 150kA Icu at 415V AC, 4 poles.
