For motor loads (AC-3), the rating will be lower; this part is specified for resistive duty. The rated breaking capacity is 520 A at 440 V, and the rated making capacity is 650 A at 440 V — these numbers tell you the contactor can close into and interrupt fault currents up to those levels, which is what IEC 60947-4-1 certifies for coordination with upstream protection.
The 4-pole arrangement is 2 NO + 2 NC, and there are no built-in auxiliary contacts — if you need auxiliaries, they are added separately. Tightening torque is 5 N·m on the power side and 1.2 N·m on the control side. The IP2X degree of protection means it is finger-safe but not sealed; install inside a panel or enclosure.
Durability and environment
Mechanical durability is rated at 5 million cycles; electrical durability in AC-1 is 350,000 cycles. The maximum operating rate is 1200 cycles per hour at 60 °C. It carries TH protective treatment per IEC 60068-2-30 for humid environments. The fire resistance is 850 °C per IEC 60695-2-1.
