The Schneider Electric C12E44V160L is a ComPacT NSXm moulded-case circuit breaker rated 160 A at 40 °C, four-pole, with a MicroLogic 4.1 electronic trip unit and integrated earth-leakage protection. This is a current-production part.
If your enclosure runs hotter, you'll need to derate per the manufacturer's curve. The electronic MicroLogic 4.1 trip unit gives you adjustable thermal and magnetic protection curves, plus the integrated earth-leakage (Vigi) module with selectable sensitivity from 30 mA to 5 A, class A or AC — so it covers both personnel protection and equipment ground-fault on the same device.
Mounts on a backplate in horizontal or vertical orientation — flat on the back, no DIN-rail clip. It's 108 mm wide (12 module pitches at 9 mm), 144 mm tall, 80 mm deep. Connections are front-facing, top and bottom, via Everlink lugs that accept 2.5–95 mm² rigid or stranded copper/aluminium. The neutral is on the left.
