Rated for 37 kW at 400 V 50 Hz and 18.6 kW at 690 V, this contactor handles the motor starting and stopping duties common on pumps, conveyors, and compressors in a 400 V three-phase line.
The main current circuit uses screw-type terminals, accepting solid conductors 2x (0.25... 2.5 mm²) and stranded 2x (10... 50 mm²). That range covers control wiring up to motor power cables, so you can land both the coil wires and the load conductors without adapters. Switching capacity at 24 V is 10 A, at 230 V is 6 A, and at 400 V is 3 A — these are the contactor's rated operational currents for the main contacts across common control and power voltages. The AC-1 maximum switching rate is 1 000 cycles per hour, AC-3 also 1 000 1/h, while AC-4 (plugging/inching) is limited to 300 1/h, which governs how aggressively you can cycle the load. Arcing time spans 10 to 19 ms at AC, with a narrower 10 to 15 ms window for the arc itself. That's fast enough to limit contact wear in normal motor switching but matters if you're coordinating with upstream protection — the arc clears before the breaker's short-time delay. IP20 on the front with the cover or box terminal installed; the terminal body itself is IP00. That means the front is touch-safe in a closed panel, but the wiring compartment expects enclosure protection — standard for a panel-mounted contactor.
