Product details

The Schneider Electric C11N44V025L is a ComPacT NSXm 63N frame moulded-case circuit breaker, 4-pole, with a MicroLogic 4.1 electronic trip unit rated 25 A at 40 °C. The integrated earth-leakage protection covers Class A and Class AC sensitivities from 30 mA to 5 A, so it handles both personnel protection and equipment ground-fault detection in one device.

The front-facing Everlink lugs accept 2.5–70 mm² fine-stranded copper or 2.5–95 mm² rigid copper/aluminium, which covers most panel feed and distribution wiring without adapters. At 80 mm deep and 108 mm wide, it occupies 12 module pitches on a 9 mm grid — a compact footprint for a 4-pole 50 kA breaker with integrated earth leakage.

IP40 front panel, IK07 impact resistance. Electrical endurance is 20,000 cycles at rated current, 10,000 at 2× In; mechanical endurance 20,000 cycles. The electronic trip unit includes a 20-minute thermal memory that retains the thermal state before and after a trip, preventing nuisance re-closure on a hot conductor.
