The MicroLogic 4.1 electronic trip unit adds integrated earth-leakage protection with selectable sensitivity from 30 mA to 5 A (class A or AC), so it handles both overcurrent and ground-fault detection in a single device — no separate RCCB needed downstream. The 4P configuration with neutral on the left and front-facing compression-lug/busbar terminals simplifies busbar routing in a standard backplate-mounted panel. The 12-module 9 mm pitch and 108 mm width define the DIN-rail footprint. Integrated earth-leakage protection means this MCCB replaces a separate RCD in the same panel space — the MicroLogic 4.1 trip unit senses both overcurrent and residual current through the same set of conductors. Sensitivity is field-adjustable across 30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, and 5 A for class A or class AC detection. For a distribution board feeding socket outlets or wet-area circuits, 30 mA class A covers personnel protection; 300 mA or higher suits fire-prevention on submain feeders. IP40 front face and IK07 impact resistance suit enclosed distribution boards. Overvoltage category IV confirms it can be installed at the service entrance or main distribution panel, not just subdistribution.","metaTitle":"Schneider Electric C11E44V050B ComPacT NSXm MCCB, 50 A, 4P,","metaDescription":"Schneider Electric C11E44V050B ComPacT NSXm MCCB. 50 A, 4P, 16 kA at 415 V AC, MicroLogic 4.1 electronic trip unit with integrated earth-leakage.
