Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, adequate for most sub-distribution boards fed by a transformer of typical impedance.
Rated current is 2 A at 30 °C ambient, derating to 1.6 A at 70 °C — the thermal curve matters if the RCBO sits in a warm enclosure near other heat sources. The 1 MW width (18 mm) means it occupies one modular unit on a DIN rail, leaving room for adjacent breakers or auxiliaries.
Deployment context
The -40 °C to 75 °C operating range covers cold-store antechambers and freezer corridors, but the device itself must be in a heated enclosure if ambient falls below its minimum; it is not rated for direct installation inside a -40 °C freezer.
