It breaks fault currents up to 4.5 kA per EN 60898 and IEC 60947-2 at 400 V AC.
The 70 mm installation depth plus 76 mm overall depth leaves clearance behind a standard 80 mm deep enclosure. Accepts solid or stranded copper from 0.75 mm² up to 25 mm²; tighten screw terminals to 2.5–3 N·m. Sealable — useful for revenue-metering or tamper-evident installations. Halogen-free and silicon-free construction suits environments sensitive to outgassing, such as clean rooms or certain medical facilities.
Rated for 400 V AC between phases, with a maximum of 440 V AC in multi-phase operation. DC rating is 60 V maximum, so it is not a primary choice for DC circuits above that voltage. Overvoltage category III and energy limiting class 3. Does not switch the neutral conductor (2-pole, both poles are protected).
