Vacuum contactors use a sealed vacuum interrupter to extinguish the arc, which means no arc chute maintenance and a clean make/break — relevant for frequent switching or harsh environments where contact erosion from arcing is a concern. The Size S10 frame carries a rated voltage of 575 to 600 V AC and accepts stranded cable from 70 up to 240 mm² on the main power terminals. Mechanical life is listed at 10 million operating cycles typical, and the contactor is rated for up to 750 operations per hour under AC-3 duty (motor switching) and AC-1 (resistive) loads. That puts it in the heavy-duty category for a contactor this size — it can handle high inrush from motor starts without premature wear.
Mounting and integration into a panel
Mounting is by screw fixing through a single 11 mm hole. The contactor measures 210 mm high, 145 mm wide, and 206 mm deep — that's a substantial footprint, so check your backplate layout before committing. The magnet coil connection uses screw-type terminals. Auxiliary switch is included (yes), so you've got at least one N.O./N.C. set for feedback to the PLC or status indication without adding a separate block.
