Integrator's terse spec recap
The Siemens SIRIUS 3RT1375-6AP36 is a size S12 contactor with a screw-type coil terminal and an AC coil rated 100-250 V, pulling 17.5 VA at both 50 and 60 Hz. It carries 2 instantaneous NO auxiliary contacts, with a rated operational current of 4 A at 230 V and 3 A at 400 V, among other voltage-specific ratings. Mounting is by screw fixing on a vertical surface, with the option to rotate ±180° or tilt ±30° forward/backward, and it requires 10 mm clearance upwards, downwards, and at the side, plus 20 mm forwards.
Panel integration and wiring
The contactor accepts solid or stranded conductors: 1x or 2x wires in the 1-4 mm² range, which covers standard control wiring for motor starters. Dimensions are 184 mm wide, 225 mm high, and 180 mm deep, so it occupies a significant footprint on the back panel or DIN-rail adapter plate.
