The C11N34V050B is a Schneider Electric ComPacT NSXm earth leakage circuit breaker (ELCB) with integrated earth-leakage protection, rated 50 A at 40 °C, 3 poles, with a breaking capacity of 50 kA at 415 V AC (performance level N). It carries a MicroLogic 4.1 electronic trip unit and is designed for distribution applications in commercial and industrial panels.
The integrated earth-leakage protection is adjustable across a wide sensitivity range: 30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, and 5 A, for both class A and class AC fault types. That covers everything from personnel protection (30 mA) to fire protection (300 mA) to feeder protection (1 A and above) — one device, one panel cutout. Rated to EN/IEC 60947-2, the standard for low-voltage circuit breakers in industrial applications. Overvoltage category IV and pollution degree 3 mean it's rated for main incoming supply panels in harsh environments — not just sub-distribution.
Width 108 mm, height 144 mm, depth 80 mm, occupying 9 module pitches at 9 mm each. IP40 front face, IK07 impact resistance — suitable for enclosed panel installation where tools are required to access live parts.
