Fastening is via screw fixing through an 11 mm hole. Dimensions are 210 mm height, 145 mm width, 202 mm depth — a substantial footprint that needs clear space: 10 mm upwards, 20 mm forwards, 10 mm downwards, 10 mm at the side for arc clearance and cooling. Rated for AC-1 resistive loads at 700 operations per hour maximum, AC-3 motor switching at 500 ops/h, and AC-4 inching/jogging at 130 ops/h. DC-1 and DC-3/DC-5 both rate 250 ops/h. The arcing time sits at 10–15 ms, with an on/off delay of 80–100 ms at DC. Auxiliary switch is included, and the terminal accepts 2x (0.25–2.5 mm²) solid or stranded wire — typical for control-circuit connections. ## Environmental and mounting notes The contactor is rated for 10 million typical mechanical operations.","metaTitle":"Siemens 3RT1066-2XB46-0LA2 SIRIUS Power Contactor, S10, 24 V","metaDescription":"Siemens SIRIUS 3RT1066-2XB46-0LA2 power contactor, size S10, 24 VDC coil, 6 A at 24 VDC.
