Its 85 kA Icu at 240 V AC and 50 kA at 415 V AC (per IEC 60947-2) means it can interrupt high fault currents without upstream cascading — a key spec for distribution panels where available fault current is high. The LCD display and energy-metering measurement type let you track load data directly at the breaker, which saves a panel builder from adding a separate power meter. ## Trip unit and protection logic The MicroLogic 2.0 E is an electronic trip unit with a 20-minute thermal memory — after a trip, it remembers the heat history so re-closing too soon doesn't cause nuisance tripping on a still-hot breaker. That matters on motor or transformer feeders where the load might re-energise while the internal temperature is still elevated. Protection is L (long-time overload) and I (instantaneous short-circuit); no short-time or ground-fault curve here, so it's suited for distribution rather than selective coordination downstream. ## Mechanical and electrical endurance Rated for 10,000 mechanical cycles and 1,000 electrical cycles at full rated current (690 V), with higher counts at reduced loads — 2,000 cycles at In/2 and 5,000 cycles at 440 V In/2. That's typical for a fixed-mount distribution breaker; it's not a switching device for frequent motor starts, but it handles routine isolation and fault clearing without wearing out early. Fixed mount on a backplate, front-connected top and bottom, with a 70 mm connection pitch.","metaTitle":"Schneider C160N42EFM ComPacT NS 1600A 4P 85kA 240V AC MCCB","metaDescription":"Schneider Electric C160N42EFM ComPacT NS new generation MCCB, 1600 A at 50 °C, 85 kA Icu at 240 V AC, MicroLogic 2.0 E trip unit, EN/IEC 60947-2.
