Screw-fixing mount, with a vertical mounting surface that can be rotated ±90° or tilted ±22.5° front-to-back — gives you some wiggle when the backplate is already drilled. Coil pulls in on 110–127 V AC or DC; operating time is 40–80 ms on either supply, and the arcing time sits between 10 and 15 ms. That's fast enough for most motor-starting sequences but not so fast you'll get nuisance dropouts on a sagging line. Rated for AC-3 duty at 500 switching cycles per hour maximum — that's the motor-switching rating that matters for a conveyor or pump contactor. AC-4 (plugging / inching) is 130 ops/h; AC-1 (resistive) is 800 ops/h. Pick your duty class; the contactor's life depends on it.
Terminals and wiring
Main power lugs accept stranded copper from 70 up to 240 mm² — that's a serious cable range, sized for the S10 frame's current-carrying capability. Auxiliary switch is included as standard, so you've got at least one N.O./N.C. set for feedback or interlocking without bolting on an extra block.
Dimensions are 210 mm high, 145 mm wide, 202 mm deep — that's the S10 footprint. Keep those gaps clear for arc flash and cooling. Mounting holes: one per side, 11 mm diameter, for M10 or similar hardware. Screw fixing means you'll need a wrench or impact driver on the backplate — no DIN-rail clip here.
