At 690 V AC-3, the rating drops to 11.4 kW; for AC-4 (plugging/inching) at 400 V, the contactor handles 35 A. Auxiliary contacts are rated for switching at several control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V. These ratings cover the typical PLC or relay interface signals in the control circuit.
Main current circuit connections use screw-type terminals. The solid conductor range accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²). Stranded conductors accept 2x (0.75 to 25 mm²). The minimum permissible cross-section at 40 °C is 16 mm² for the main circuit.
Mechanical life is typical at 10,000,000 operating cycles. Maximum switching frequency varies by duty: 1,200 cycles/hour at AC-1, 1,000 at AC-3, 600 at AC-2, and 300 at AC-4.
