MCCB for distribution — 50 A, 50 kA, electronic trip
The Schneider Electric C11N44V050L is a ComPacT NSXm moulded-case circuit breaker, 4-pole, rated 50 A at 40 °C with a MicroLogic 4.1 electronic trip unit. The electronic trip includes integrated earth-leakage protection, adjustable from 30 mA to 5 A for class A or class AC sensitivity, so it covers both personnel and equipment ground-fault needs in one device.

Front-facing connections top and bottom; Everlink lugs accept 2.5–95 mm² rigid or stranded copper/aluminium (fine stranded copper up to 70 mm²). Connection pitch is 35 mm with spreaders, 27 mm without. IP40 front face, IK07 impact resistance — suitable for enclosed panel installation where occasional contact is expected.
Mechanical durability matches at 20,000 cycles.
