The coil pulls in on 200–277 V AC. Mechanical switching life is listed at 10 million operations typical, which puts it in the heavy-duty range for a contactor this size — expect it to outlast the machine it's in on cyclic loads like conveyors or pumps.
The contactor is rated for AC-3 maximum switching frequency of 750 operations per hour, and AC-4 at 130 operations per hour.
Mounting is screw fixing, not DIN rail snap-on. The contactor size S6 is physically large (172 mm high, 120 mm wide, 170 mm deep) — you're bolting this to a backplate, not clipping it onto a rail. That's tight for a part this size; plan your enclosure depth accordingly. The mounting position allows vertical surface mounting with ±90° rotation or ±22.5° tilt front-to-back, so panel layout isn't locked to one orientation.
Main power circuit terminals accept stranded wire from 25 mm² up to 120 mm² — that's a heavy lug range, consistent with a size S6 contactor rated for high current. That gives flexibility for daisy-chaining control power or feedback loops without extra terminal blocks.
