It switches a 225 A rated operational current at ≤440 V AC (AC-3), handling motor loads up to 200 kW at 380/400 V AC or 220 kW at 440 V AC. The 115 V AC 50/60 Hz control coil pulls 805 VA inrush at 50 Hz, 970 VA at 60 Hz. Mechanical interlocking between the star, line, and delta contactors prevents simultaneous closure — a standard safeguard for star-delta transition.
The 225 A AC-3 rating at ≤440 V defines the motor-switching capacity under IEC 60947-4-1. For a 200 kW motor at 400 V, this starter handles the locked-rotor inrush and breaks the running current without welding contacts. The 115 V AC coil (0.85–1.1 Uc operational range) is standard for North American and many European control circuits — verify your panel's control transformer matches. The 3 x 3P pole configuration (three NO power poles per contactor) is built for three-phase star-delta transition; the auxiliary contact composition includes 1 NO + 1 NC for the star contactor, 1 NO + 2 NC for the line contactor, and 2 NO + 1 NC for the delta contactor — enough for self-holding and status feedback without adding an aux block.
This is a plate-mounted unit (not DIN-rail), sized 525 mm wide × 110 mm high × 235 mm deep. The power circuit terminates on M10 bolted connections accepting busbars up to 32 × 4 mm or lugs up to 185 mm². Control wiring uses screw clamp terminals accepting 1–4 mm² flexible or solid. The IP20 front face (with shrouds) suits enclosed panel installation — not washdown environments.
