Product details

SIRIUS S10 Power Contactor — 200-220 V Coil, Screw Terminals

It accepts stranded cable from 70 up to 240 mm² on the main poles — sized for high-current motor or resistive loads in a control panel. Rated for AC-3 duty at 500 operating cycles per hour maximum, this contactor handles the switching of squirrel-cage motors under load. The AC-4 rating of 130 ops/h covers plugging and inching applications where the contactor breaks stalled-rotor current.

Mounts via screw fixing on a vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back. The envelope is 210 mm high, 145 mm wide, 202 mm deep — confirm panel depth clearance before laying out the gland plate.
