The contactor measures 210 mm high by 165 mm wide by 202 mm deep, mounts via screw fixing through an 11 mm hole, and requires 10 mm clearance above and below, 20 mm forward, and 10 mm at the sides for arc-flash and ventilation. Rated for AC-3 switching at up to 500 operations per hour and AC-4 at 130 ops/h, with an arcing time of 10 to 15 ms and pick-up/drop-out times of 80 to 100 ms on both AC and DC control. ## Coil and Auxiliary Contact Ratings The coil pulls in at 80% of rated voltage and drops out at a full-scale value of 1.1; the control supply range is 200 to 277 V AC at 50/60 Hz. Auxiliary contacts are rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are the make/break capacities for the integrated aux blocks. Screw-type terminals accept solid conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or a maximum of 2x 0.75 to 4 mm² per clamp. Typical mechanical life of the contactor is 10 million operations.","metaTitle":"Siemens 3RT1066-6PP35-0SW0 SIRIUS S10 Power Contactor, 200-2","metaDescription":"Siemens SIRIUS 3RT1066-6PP35-0SW0 S10 power contactor. 200-277V AC 50/60Hz coil, screw terminals, 202mm depth.
