The toggle control and backplate mounting suit standard panel layouts. At 40 A continuous and 50 kA Icu at 415 V AC, this breaker handles typical 40 A feeder or motor circuits in a 400 V distribution system without needing an upstream current-limiting fuse. The electronic trip unit (MicroLogic 2.2) provides adjustable long-time pickup and delay, plus fixed short-time and instantaneous settings — useful for coordinating with downstream branch breakers in a selective-coordination study. The 4-pole (4P) configuration with neutral on the left covers three-phase plus neutral systems common in European and Asian panel designs. Backplate mounting with front-connect terminals (both upside and downside). IP40 front face and IK07 impact rating suit enclosed panel installation — not for washdown zones. The 5 accessory slots allow field-installable aux contacts, shunt trips, or under-voltage releases without removing the breaker from the panel.","metaTitle":"Schneider Electric C10N42D040 ComPacT NSX 40A 4P MCCB, 50kA","metaDescription":"Schneider Electric C10N42D040 ComPacT NSX circuit breaker, 40A rated, 4-pole, 50 kA at 415 V AC.
