Product details

SIRIUS S12 power contactor — 3RT5075-6AR36

The Siemens 3RT5075-6AR36 is a SIRIUS power contactor in the S12 frame size, rated for motor switching up to 263 kW at 400 V at 60 °C and 151 kW at 230 V at 60 °C.

Fastened via screw fixing to a vertical mounting surface, the contactor can be rotated ±90° or tilted ±22.5° front-to-back. Side-by-side mounting is permitted, which simplifies multi-contactor panels. Dimensions are 214 mm high, 160 mm wide, and 225 mm deep.

Rated for 2 000 operating cycles per hour at both AC and DC. Maximum switching rates vary by duty: AC-1 resistive loads up to 700 cycles/h, AC-3 motor loads up to 500 cycles/h, and AC-4 plugging/reversing up to 130 cycles/h. The coil draws 6 A at 24 V rated value, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V.

Frequently asked questions

What are the key ratings of 3RT5075-6AR36?

This SIRIUS S12 power contactor is rated 263 kW at 400 V at 60 °C and 151 kW at 230 V at 60 °C, with an insulation voltage of 1 000 V.

Where can I buy 3RT5075-6AR36?

This part is sourced and quoted to order against an RFQ through independent distribution, with availability and current pricing confirmed at quote time.

What is the difference between 3RT5075-6AR36 and 3RT5075-6AP36?

The 3RT5075-6AP36 is a peer variant in the same S12 frame size. The key difference is the coil voltage and suppressor configuration — the 6AR36 includes a varistor suppressor, while the 6AP36 uses a different coil variant. Both share the same power ratings and mounting footprint.
