Rated at 22 kW at 500 V and 11.4 kW at 690 V, it handles motor starting and stopping in AC-3 duty. Auxiliary contact ratings span 10 A at 24 V down to 0.3 A at 220 V, covering control-circuit switching across common AC and DC voltages.
The 22 kW at 500 V rating means this contactor can switch a 22 kW induction motor on a 500 V three-phase line — that is the headline sizing figure for AC-3 duty. The 690 V rating of 11.4 kW reflects the lower current available at higher voltage for the same contactor frame. Mechanical endurance of 10 million operations means the contactor's mechanical life is rated for that many no-load cycles; electrical life depends on the switching current and duty class. Switching frequency limits are 1 200 cycles/hour at AC-1, 1 000 at AC-3, and 300 at AC-4 — the buyer should match the application's duty cycle to these limits.
Main circuit terminals accept stranded wire from 2x 0.75 mm² up to 2x 25 mm², or solid/stranded up to 2x 16 mm². Auxiliary/control terminals accept solid wire from 2x 0.5 mm² up to 2x 4 mm², or stranded up to 2x 2.5 mm². This covers typical motor feeder and control wiring sizes. Dimensions are 112 mm height, 55 mm width, 115 mm depth — the depth is the dimension behind the panel face when DIN-rail mounted.
