Product details

It carries a 65 A rating at 480 V, which governs its use on 480 V three-phase motor circuits up to that full-load current. The contactor includes an integrated auxiliary switch block, saving a DIN-rail slot versus a separate add-on.

The intended mounting position is standing on a horizontal surface. The magnet coil termination uses screw-type terminals; main contact wiring accepts 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²).

Switching duty and operating limits

Rated for AC-3 duty at 500 switching cycles per hour maximum, and AC-4 at 150 per hour. The AC-3e rating also caps at 500 per hour. Arcing time spans 10 to 20 ms; the make/break time at AC is 10 to 18 ms. The auxiliary contact ratings are load-dependent: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The main contactor has a typical mechanical life of 10,000,000 operations.
