This is a distribution-grade MCCB with integrated earth-leakage protection, selectable from 30 mA up to 5 A for class A or class AC residual currents. Above 40 °C, the electronic trip unit derates per the thermal curve — the 50 A figure is the baseline, not the ceiling. The MicroLogic 4.1 electronic trip unit provides adjustable thermal-magnetic protection curves plus the integrated earth-leakage function. Overvoltage category IV confirms it is suitable for the main distribution point (utility entrance or main panel), not just downstream branch circuits. ## Deployment context This MCCB mounts to a backplate, not a DIN rail. It occupies 12 module pitches at 9 mm each (108 mm width). The 144 mm height and 80 mm depth fit standard distribution enclosures. Front-facing connections accept compression lugs or busbars; the connection pitch is 35 mm with spreaders, 27 mm without. IP40 protection means it is guarded against tools and small objects but not water ingress — suitable for indoor panel installation. IK07 impact resistance handles typical handling during installation. The grey RAL 7016 colour is standard for Schneider switchgear.","metaTitle":"C11F44V050B ComPacT NSXm 50A 4P MCCB, 36kA 415V AC","metaDescription":"Schneider Electric C11F44V050B ComPacT NSXm MCCB, 50A at 40°C, 4P, 36kA at 415V AC, MicroLogic 4.1 electronic trip.
