Product details

Panel integration brief

The C11B44V025L is a 4-pole ComPacT NSXm MCCB rated 25 A at 40 °C with a 25 kA breaking capacity at 415 V AC (performance level B). It uses a MicroLogic 4.1 electronic trip unit with integrated earth-leakage protection, selectable from 30 mA to 5 A for class A or AC. The 108 mm wide, 144 mm tall, 80 mm deep footprint mounts on a backplate in horizontal or vertical orientation.

Above that temperature, derate per the thermal curve. The electronic MicroLogic 4.1 trip unit provides adjustable earth-leakage thresholds (30 mA to 5 A) and a thermal memory that holds the heat profile for 20 minutes before and after tripping — useful for preventing nuisance trips on reclose after a transient overload.

The C11B44V025L is listed as current production. No official successor or cross-reference exists for this exact order code.
