It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, so it drops into a standard panel layout without adapter plates — the 75 mm width and 130 mm depth tell you the footprint it takes up on the rail and how far it reaches into the enclosure.
The magnet coil uses screw-type terminals, and the main contact wiring accepts 2x (0.5... 1.5 mm²) solid or 2x (0.75... 2.5 mm²) stranded — that covers the typical control-circuit and motor-lead sizes you'd run for an S2-frame contactor. No ferrule crimping required for the solid wire, which saves a step on the panel build.
Mounting flexibility
The mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5° — useful if the panel layout forces an odd angle or you're retrofitting into an existing enclosure where the DIN rail isn't level. Clearances: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm to the side — tight enough for dense packing but leave the side gap for heat dissipation.
