It combines a thermal-magnetic overcurrent trip (curve B, 3...5 x In magnetic threshold) and integrated earth-leakage protection in a single 1P+N module, saving a DIN-rail position compared to a separate MCB and RCCB. Breaking capacity is 6000 A Icn at 230...240 V AC, 50 Hz, per EN/IEC 61009-2-1 — sufficient for most residential and light commercial distribution boards where the prospective short-circuit current stays under that threshold. The limitation class 3 rating means it limits let-through energy well, aiding downstream coordination.
Installation and mounting
Clip-on mounting to DIN rail, occupying 4 pitches at 9 mm per pole (36 mm total width). Neutral is on the left, phase on the right — check busbar orientation before committing the assembly. Terminals accept 1...16 mm² rigid or 1...10 mm² flexible (with or without ferrule); tightening torque is 2 N.m, strip length 15 mm. IP20 on the device body, IP40 inside a modular enclosure per IEC 60529.
Environmental and durability
Electrical and mechanical durability each rated at 20,000 cycles, which aligns with typical panel life in non-frequent-switching distribution roles.
