The C12F44V160L is a Schneider Electric ComPacT NSXm moulded-case circuit breaker rated 160 A at 40 °C, four-pole (4P), with a 36 kA interrupting capacity at 415 V AC — that is the F performance level, meaning it clears faults up to that level without upstream cascading in a 415 V distribution board. The electronic MicroLogic 4.1 trip unit gives you adjustable thermal memory (20 minutes before and after tripping) and integrated earth-leakage protection selectable from 30 mA to 5 A, Class A or AC, so you can tune the sensitivity to the circuit without adding a separate module. Mounts flat on the backplate, horizontal or vertical, front-connected both top and bottom.
Rated IP40 (finger-safe, no water ingress) and IK07 (2 J impact resistance), so it lives in a clean indoor panel — not a washdown zone. Connection terminals accept Everlink lugs: 2.5 to 70 mm² fine-stranded copper, or up to 95 mm² rigid/stranded aluminium/copper. The 12-module 9 mm pitch width (108 mm) and 144 mm height fit standard backplate layouts. Neutral is on the left, which matters for busbar ordering.
Overvoltage category IV (for main incoming supply). Utilisation category A — not intended for frequent switching under load, but for distribution protection. Electrical durability: 20 000 cycles at 440 V at In/2, 10 000 cycles at In. Mechanical durability: 20 000 cycles. The grey RAL 7016 colour is the standard ComPacT NSXm finish.
