The C11B34V100L is a 3-pole earth leakage circuit breaker from the ComPacT NSXm range, rated 100 A at 40 °C with a MicroLogic 4.1 electronic trip unit. The electronic trip unit includes integrated earth-leakage protection with adjustable sensitivity from 30 mA up to 5 A, covering both class A and class AC residual current types. That means one device handles both overcurrent and ground-fault protection, saving a module of DIN space.
The 9-module pitch (108 mm wide, 144 mm high, 80 mm deep) fits a standard distribution board footprint. Front-facing connections on both line and load sides, with Everlink terminals that accept 2.5 to 95 mm² rigid aluminium/copper or 2.5 to 70 mm² fine-stranded copper. Connection pitch is 35 mm with spreaders, 27 mm without — useful to know when you're laying out gland plates and busbar droppers.
Rated IP40 (finger protection) and IK07 (impact resistance up to 2 J). Overvoltage category IV means it's rated for installation at the origin of the installation, not just downstream sub-distribution. The lifecycle status is current production — no end-of-life notice, no last-time-buy window to track.
Durability and duty
Mechanical durability rated at 20,000 cycles. Electrical durability: 20,000 cycles at 440 V at rated current (In/2), 10,000 cycles at 440 V at full rated current (In). Local signalling flag (green) confirms presence of auxiliary contacts without needing to pull the breaker.
