Product details

Siemens SIRIUS 3RT1065-2AT36 — S10 Power Contactor

Its rated insulation voltage of 575 to 600 V suits 400 VAC line-fed systems with margin. The contactor mounts via screw fixing onto a vertical surface, with ±90° rotatability and ±22.5° tilt front-to-back, giving panel builders flexibility in tight enclosures. Main power terminals accept stranded conductors from 70 to 240 mm², while the coil connection uses spring-type terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded wire. The auxiliary switch is included, with rated contact currents of 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. Switching frequency varies by duty class: up to 800 operations per hour at AC-1 (resistive), 500/h at AC-3 (motor start/run), 250/h at AC-2 (slip-ring motor), and 130/h at AC-4 (plugging/inching).

The 3RT1065-2AT36 measures 210 mm high, 145 mm wide, and 202 mm deep. The single mounting hole has an 11 mm diameter.

Frequently asked questions

Where can I buy 3RT1065-2AT36 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quote.

What are the key dimensions of 3RT1065-2AT36?

The contactor is 210 mm high, 145 mm wide, and 202 mm deep. Minimum clearance distances are 10 mm upwards, 10 mm downwards, 10 mm at the sides, and 20 mm forwards.

What conductor sizes does 3RT1065-2AT36 accept?

Main power terminals accept stranded conductors from 70 to 240 mm². The coil connection uses spring-type terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded wire.

What is the switching frequency for different duty classes?

Maximum switching frequency is 800 operations per hour at AC-1 (resistive), 500/h at AC-3 (motor start/run), 250/h at AC-2 (slip-ring motor), and 130/h at AC-4 (plugging/inching).
