Rated 22 kW at 400 V in AC-2, with an AC-4 breaking current of 41 A at 400 V for plugging or inching duty.
Screw-type terminals on the main circuit accept solid conductors up to 2x 4 mm² or stranded up to 2x 25 mm² — the stranded range covers the full S2 current capability without needing lug adapters. Side-by-side mounting allowed, so multiple contactors pack tight in a row.
The actual electrical endurance depends on the duty cycle: AC-1 (resistive) allows 1,000 operations per hour, AC-3 (standard motor start) allows 800/h, AC-4 (plugging/inching) drops to 300/h. The arcing time of 10-15 ms and AC operating time of 7-20 ms are the window you need for coordination with upstream short-circuit protection — the contactor clears fast enough to let a motor circuit protector or fuse do its job without welding the main contacts.
