Product details

The MicroLogic 4.1 electronic trip unit handles the overcurrent and earth-fault sensing, with selectable earth-leakage sensitivity from 30 mA up to 5 A for both class A and class AC detection. This is a current-production part per the lifecycle stage.

The B 25 kA at 415 V AC rating means this breaker can safely interrupt a fault current up to 25,000 A without failing catastrophically — that is the SCCR (short-circuit current rating) for the device itself, per EN/IEC 60947-2. In a distribution panel, that figure governs whether the breaker coordinates with the upstream protective device. Integrated earth-leakage protection eliminates the need for a separate RCD module. Sensitivity is field-selectable across 30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, and 5 A for both class A (pulsating DC) and class AC (sinusoidal AC) fault types.

Mounts on a backplate, not a DIN rail. The 9-module pitch (108 mm width, 144 mm height, 80 mm depth) occupies a fixed footprint in the enclosure.

Frequently asked questions
