The C11N34V025L is a Schneider Electric ComPacT NSXm earth leakage circuit breaker — a 3-pole, 25 A unit with an electronic MicroLogic 4.1 trip unit and integrated earth-leakage protection. It's built to EN/IEC 60947-2, Category A utilisation, meaning it's rated for distribution duty: protecting cables and busbars, not motor starts.
That matters on a panel feeding a cyclic load like a compressor bank. Integrated earth leakage means you get adjustable sensitivity from 30 mA to 5 A, class A or AC. No separate RCCB module to wire in — saves two modules of DIN width and one interconnection. The Everlink terminals accept up to 95 mm² rigid copper or 70 mm² fine-stranded, so it'll take a feeder cable without a reducer lug. IP40 front face, IK07 impact rating — standard for a distribution board, not for a washdown zone.
Mounts on a backplate — not DIN rail — so you're bolting it to a panel or chassis. 9-module pitch, 108 mm wide, 144 mm tall, 80 mm deep. Connections are front-facing top and bottom, which wires up clean in a row of breakers. The flag indicator (green) shows auxiliary contact presence without opening the cover.
Current production — no phase-out notice on record.
