It switches a 4 kW motor at 400 V AC (AC-3 duty) and carries a 100 kA short-circuit breaking capacity at 400 V, so it can interrupt a fault up to that level without upstream devices needing to clear it — that's the SCCR the panel label needs. That's a standard feature on SIRIUS 3RV1 breakers, not an add-on accessory.
IP20 on the front — finger-safe for the panel face, but not washdown-rated; keep it inside a cabinet. Terminals accept solid and stranded copper: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²) per clamp, with AWG equivalents 2x (14 … 10) for the main contacts. Finely stranded with ferrule is also supported. That covers most motor feeder cables up to 6 mm².
Shock-rated at 25g / 11 ms — tough enough for machine-mounted panels on presses or conveyors. Above that, you'd need to account for reduced air density on the arc extinction and thermal dissipation. That's warm but manageable in a ventilated enclosure; factor it into the panel thermal budget if you're packing several in a row.
