The Schneider Electric C11F44V025L is a ComPacT NSXm 4-pole molded-case circuit breaker with a MicroLogic 4.1 electronic trip unit rated 25 A at 40 °C. The integrated earth-leakage protection covers both class A and class AC fault types, with selectable sensitivity from 30 mA up to 5 A, so it serves as a combined overcurrent and ground-fault device in a single DIN-rail footprint.
Trip unit and protection characteristics
That matters for motor or transformer feeders where repeated close-in faults can overheat the conductors even if the instantaneous trip resets. The trip unit is rated category A (no intentional short-time delay), so it's suited for distribution feeders where instantaneous coordination with downstream devices is the goal.
Mounting and connection details
The Everlink lug terminals accept copper conductors from 2.5 mm² up to 70 mm² fine-stranded, or rigid aluminium/copper up to 95 mm² — covers the range for a 25 A feeder without needing adapters. Connection pitch is 35 mm with spreaders, 27 mm without. The 4-pole unit occupies 12 module pitches at 9 mm each, so it fits a standard 108 mm wide DIN-rail slot. IP40 enclosure protection, IK07 impact resistance.
