Its headline rating is 500 A in AC-3e duty at 400 V, which means it handles the inrush and running current of motors up to 250 kW at 400 V — the AC-3e category adds an endurance margin over standard AC-3 for high-cycle applications. For North American installations, the same contactor delivers 400 hp at 460/480 V 60 Hz, covering large pump, compressor, and conveyor drives common in industrial plants.
Drop-out occurs between 0.1 and 0.45 Uc, so it releases reliably on undervoltage conditions. Mechanical durability is rated at 8 million cycles, and the maximum operating rate reaches 600 cycles/hour in AC-3 and AC-3e, 300 in AC-1, and 150 in AC-4. For applications requiring frequent jogging or plugging, the AC-4 rating of 250 kW at 400 V confirms it can handle the severe switching duty of reversing or inching. Power connections accept bar or busbar up to 32 x 10 mm, lugs up to 185 mm², or bolted connections — the 45 mm pole pitch and 35 N·m tightening torque suit panel builders working with large cable lugs. The auxiliary contact block is built in with 1 NO + 1 NC, sufficient for basic status feedback or interlocking without an add-on module.
This contactor carries certification to EN/IEC 60947-4-1 and -5-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, plus JIS C8201-4-1 and -5-1. It also meets IEC 60335-1 Clause 30.2 and IEC 60335-2-40 Annex JJ for appliance applications — relevant if the contactor is specified into HVAC or refrigeration equipment.
Deployment context
Mounting is plate-based (not DIN rail), so it requires a backplate or sub-panel with drilled mounting holes matching the 226 mm depth and 140 mm width footprint. The IP2X front-face protection with shrouds meets IEC 60529 and VDE 0106 for finger-safe installation inside an enclosure.
