50 A TeSys D contactor sized for 22 kW motor switching
The LC1 D5011F7: It carries 1 NO + 1 NC auxiliary contact on the front face for the hold-in or indicator circuit.
Coil, power ratings, and what 22 kW at 400 V actually covers
The 110 V AC coil closes the contactor from the control supply; the main poles are rated to switch motor loads drawing up to 22 kW at 400 V in AC-3 duty — that covers three-phase induction motors roughly 28-30 hp at 400 V, the size range typically seen on conveyor drives, compressors, and mixer banks. Power consumption scales with the contactor frame: this size draws on the order of 22 W to hold the coil in. Insulation voltage is rated at 1000 V and impulse withstand at 8 kV, which is the level needed to ride through switching transients and nearby contactor-chatter events on an industrial bus without flashover across the open pole gap.
