Rated operational current is 630 A, and the contactor handles motor loads across a wide voltage range: 450 kW at 690 V AC, 400 kW at 440 V AC, 335 kW at 380-400 V AC, and 200 kW at 220-230 V AC, all at 50/60 Hz. For UL/CSA applications, the motor power ratings are 800 hp at 575-600 V AC, 600 hp at 460-480 V AC, 300 hp at 220-240 V AC, and 250 hp at 200-208 V AC for three-phase motors.
The 630 A rating in AC-3 duty means this contactor is sized for heavy motor switching — starting and stopping induction motors under load. Control circuit voltage is 48 V AC (50-400 Hz) or 48 V DC, with latching and unlatching limits of 0.85 to 1.1 times Uc. That means the coil must see at least 40.8 V and no more than 52.8 V to reliably latch or drop out — a tight window, so verify your control transformer regulation. Rated breaking capacity is 6300 A at 220-440 V, tapering to 3200 A at 1000 V for the power circuit. That gives selectivity headroom downstream — the contactor clears faults up to those levels without welding, provided upstream protection is coordinated. That's suitable for process lines with moderate cycling, not high-speed pick-and-place applications.
Mounts on a notched AM1-EC rail — a dedicated mounting plate, not a standard DIN rail — so plan for panel space accordingly. The contactor is 15.3 inches wide, 12.0 inches tall, and 10.04 inches deep, with bar-type terminals accepting two 60 x 5 mm bars per pole.
The contactor complies with IEC 60947-4, BS 5424, VDE 0660, NF C 63-110, and JEM 1038 standards. Associated fuse rating is 630 A aM or gG at up to 440 V for the power circuit.
