It protects a single-phase outgoing circuit (1P+N) against overloads, short-circuits, and earth faults in one device, saving a DIN rail slot versus separate MCB+RCCB. The integrated 30 mA earth-leakage sensitivity provides personal protection against direct contact faults per IEC 61009-1. Breaking capacity is 6000 A Icn at 240 V AC, 50/60 Hz, conforming to IEC 61009-1. That's the standard domestic and light commercial fault level — adequate for most final sub-circuits in TN earthing systems.
Occupies one modular slot in a distribution board or enclosure. Neutral is on the left, phase on the right — wire top-entry for incoming, bottom for outgoing. Tightening torque 3.5 N.m top, 2 N.m bottom. IP20 finger-safe; IP40 in a modular enclosure. Padlockable with a 4 mm diameter padlock for lockout/tagout. ON/OFF local signalling visible through the toggle.
