The earth-leakage protection is integrated into the breaker — no external module needed. A 20-minute thermal memory means the breaker remembers a prior overload event and will trip faster on a reclose into a still-hot conductor, which is useful for motor or transformer feeders that see repeated starts. ## Breaking capacity across voltages The C16N44V100 is rated per EN/IEC 60947-2 with the following Icu: 90 kA at 220/240 V AC, 50 kA at 380/415 V AC, 50 kA at 440 V AC, 36 kA at 500 V AC, 35 kA at 525 V AC, and 10 kA at 660/690 V AC. It also carries UL 60947-4-1 ratings: 85 kA at 240 V AC, 50 kA at 480 V AC, and 10 kA at 600 V AC. The utilisation category is A — not intended for current-limiting applications, but suitable for general distribution and feeder protection where selectivity with downstream breakers is designed in. ## Physical fit and mounting Mounts on a backplate in horizontal or vertical orientation, flat on the back. Front connections on both upside and downside. Connection pitch is 35 mm. Neutral is on the left. IP40 protection — suitable for indoor panel installation; IK07 impact resistance. ## Durability and operational life Mechanical durability is 40,000 cycles. Electrical durability varies by load: 40,000 cycles at 440 V at half rated current (In/2), 20,000 cycles at 440 V at full In, 15,000 cycles at 690 V at In/2, and 7,500 cycles at 690 V at full In. These numbers matter for a breaker that sees frequent switching — like a main disconnect on a machine that cycles every shift.","metaTitle":"Schneider Electric C16N44V100 ComPacT NSX160N, 100A, 50kA 41","metaDescription":"Schneider Electric C16N44V100 ComPacT NSX160N MCCB. 100A, 4P, MicroLogic 4.2 electronic trip. 50kA Icu at 415V AC.

do I get current pricing and availability for C16N44V100?","answer":"Submit an RFQ through the storefront.

The C16N44V100 is the 100 A, 4P, N-breaking-capacity (50 kA at 415 V) variant with MicroLogic 4.2 and integrated earth-leakage. A 100 A, 3P version would be a different order code; a higher breaking capacity (S or H code) would also be a different part number. No pin-compatible drop-in exists within the same frame — the trip unit and poles are fixed."},{"question":"What compliance documentation does the C16N44V100 carry?","answer":"The C16N44V100 is certified to EN/IEC 60947-2 and UL 60947-4-1. The IP40 rating is per IEC 60529, and the IK07 rating is per IEC 62262. Pollution degree 3 and overvoltage category IV are per IEC 60664-1.
