Product details

The Siemens 3RT1065-2AU36 is a SIRIUS S10 power contactor — the main switching device for motor loads in a control panel. It's screw-fixed to the mounting plate, not DIN-rail snapped, so plan for four 11 mm holes on a vertical surface. The S10 frame size (210 mm tall, 145 mm wide, 202 mm deep) is a common footprint in Siemens SIRIUS lines, meaning it drops into existing S10 cutouts without panel rework.

Mount it on a vertical surface, rotatable ±90° or tiltable ±22.5° forward/back. That's tight enough for a standard 600 mm deep enclosure — no need to oversize the cabinet.

Coil terminal and wiring

The magnet coil uses spring-type terminals — push-in for solid or stranded 2x (0.25…2.5 mm²). The power circuit accepts stranded cable up to 70…240 mm². That's a wide range: you can land a 70 mm² motor feed or a 240 mm² bus bar without adapters.
