The Schneider Electric C11F34V050L is a ComPacT NSXm earth leakage circuit breaker, 3-pole, rated 50 A at 40 °C with a MicroLogic 4.1 electronic trip unit.
It's 9 module pitches wide (108 mm), 144 mm tall, 80 mm deep — fits a standard distribution board. IP40 front means it's fine inside a clean panel; IK07 says it takes a light knock during installation. The Everlink terminals accept 2.5 to 70 mm² fine-stranded copper or 2.5 to 95 mm² rigid aluminium/copper, so you can land a fat feeder without a reducer.
Earth leakage built in
Integrated earth-leakage protection with selectable sensitivity: 30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, or 5 A for class AC; 30 mA through 1 A for class A. That covers everything from personnel protection (30 mA) to feeder leakage on a long cable run (5 A). The trip unit is electronic, so it's more precise than a thermal-magnetic on the leakage side — especially useful where nuisance tripping from inrush is a concern.
