Product details

The coil accepts 20-33 V, and the contactor includes an auxiliary switch, saving a separate add-on block for basic feedback or interlock signals.

The main contact configuration is 18 normally open contacts, with 1 normally closed — a high NO count suited for three-phase motor switching plus additional load circuits. At AC-3 duty (standard motor switching), the contactor is rated for 800 switching operations per hour maximum; at AC-1 (resistive loads), it can handle 1,000 per hour. The auxiliary contacts are rated for 10 A at 24 V, 2 A at 48 V or 60 V, and 0.3 A at 220 V — these ratings govern what pilot devices or PLC inputs the auxiliary circuit can drive. Operate times are 30-55 ms for both AC and DC, and arcing time is 10-20 ms; these matter for coordination with upstream protective devices. Wire sizes accepted: 2x (0.5-1.5 mm²) or 2x (0.75-2.5 mm²) solid or stranded, terminated at screw-type terminals.
