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.","metaTitle":"Siemens 3RT5075-6AR36 SIRIUS Power Contactor, 263 kW at 400","metaDescription":"Siemens 3RT5075-6AR36 SIRIUS power contactor, Size S12, rated 263 kW at 400 V 60°C.
