The Schneider Electric C11F44V100B is a ComPacT NSXm moulded-case circuit breaker rated 100 A at 40 °C with an F-class breaking capacity of 36 kA at 415 V AC. Four poles (4P) handle three-phase plus neutral in a distribution panel, backplate-mounted, with front-facing compression-lug or busbar connections. The MicroLogic 4.1 electronic trip unit provides adjustable thermal memory (20 minutes before and after tripping) and integrated earth-leakage protection selectable from 30 mA up to 5 A for class A or class AC residual currents. That earth-leakage integration means you don't need a separate RCCB downstream — one device covers both overcurrent and ground-fault protection in a single 12-module-wide footprint (108 mm wide, 144 mm high, 80 mm deep).
The grey RAL 7016 housing carries IP40 protection (finger-safe, no water ingress) and IK07 impact resistance — suitable for enclosed distribution boards where the breaker isn't exposed to washdown. Connection pitch is 35 mm with spreaders, 27 mm without. Neutral is on the left; the toggle control and a green flag for auxiliary contact status are both front-accessible.
Overvoltage category IV (suitable for mains-level incoming supply). The electronic trip unit is category A (no intentional short-time delay), which is the standard for distribution feeder breakers. Altitude rating: 2000 m without derating, 5000 m with derating. Relative humidity range 0…95 %.
