Rated frequency is 50 Hz, and it carries a maximum 440 V AC in multi-phase operation.
It occupies 4 width units (72 mm wide, 90 mm high, 76 mm deep) with a 70 mm installation depth behind the panel. Terminals accept solid or stranded copper from 0.75 mm² up to 25 mm², torqued to 2.5–3 N·m. The housing is IP20 with connected conductors, sealable, halogen-free, and silicon-free — fine for residential and infrastructure panels where off-gassing matters.
It is rated 10 kA per EN 60898 at 400 V AC, which means it safely interrupts fault currents up to that level without upstream damage.
Terminals accept solid or stranded copper from 0.75 mm² up to 25 mm², with a recommended tightening torque of 2.5 to 3 N·m.
