Its headline rating is 22 kW at AC-2 duty at 400 V — that's the current it can make and break for slip-ring motors or wound-rotor applications where the starting current is moderate. At 55 mm wide, it fits alongside other SIRIUS components without eating up rail space. Terminals are screw-type on the main current circuit, accepting 2x (0.75... 25 mm²) stranded or 2x (0.25... 2.5 mm²) solid. That covers most panel wiring up to 25 mm² for the power legs.
AC-2 duty means it's rated for starting and stopping wound-rotor motors where the inrush is controlled; if you're switching a standard squirrel-cage motor, you'd look at the AC-3 rating (not listed here, but typically lower for the same frame). The mechanical life of 10 million operations means it'll outlast most panel rebuild cycles. Storage range extends to -55 to +80 °C, so it's fine for unheated warehouses. IP20 on the front (finger-safe), IP00 at the terminals — so the wiring zone needs to be inside a locked enclosure or guarded.
