It carries a 90 kA Icu breaking capacity at 240 V AC and 50 kA at 415 V AC, per EN/IEC 60947-2. The N breaking capacity code (50 kA at 415 V AC) tells you this is the standard-interrupting version of the NSX160N frame — sized for distribution panels where fault levels sit in that range, not the high-fault H or L versions. The MicroLogic 2.2 electronic trip unit gives you L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection curves. That So function with fixed delay is key for selective coordination downstream: you can set the short-time pickup and let a fault clear closer to the load before this breaker opens, keeping upstream feeders alive. The 140 mm width, 161 mm height, and 86 mm depth fit standard distribution panel footprints. Front connections top and bottom; neutral on the left. IP40 enclosure protection (IK07 impact resistance) means it's suited for indoor panel installation where tools and accidental contact are the main concern, not washdown. The 35 mm connection pitch matches standard busbar and cable lug spacing. ## Durability and duty Mechanical durability is 40,000 cycles; electrical durability varies by load — 40,000 cycles at 440 V at half rated current, 20,000 at full 100 A, and 7,500 at 690 V. That's a solid service life for a distribution breaker in a panel that sees regular switching, not daily operation.","metaTitle":"C16N42D100 ComPacT NSX Circuit Breaker, 100 A, 90 kA","metaDescription":"Schneider Electric C16N42D100 ComPacT NSX circuit breaker, 100 A at 40 °C, 90 kA Icu at 240 V AC.
