The contactor is fastened via screw fixing and supports a mounting position with a vertical mounting surface, rotatable ±90° and tiltable ±22.5° front-to-back. Dimensions are 225 mm depth, 160 mm width, and 214 mm height, with clearance requirements of 10 mm upwards, 20 mm forwards, 10 mm downwards, and 10 mm at the side. ## Switching Performance and Duty Ratings Maximum switching frequency varies by duty: 500 operations per hour for AC-1 (resistive), AC-3 (motor starting/running), and AC-3e; 200 ops/h for AC-2 (slip-ring motor); 130 ops/h for AC-4 (plugging/inching); and 250 ops/h for DC-1, DC-3, and DC-5. Mechanical endurance is typical 10,000,000 operations. DC switching capacity at 24 V rated value is 6 A; at 48 V and 60 V, 2 A; at 110 V, 1 A; at 125 V, 0.9 A. Fastening is via screw fixing with one hole of 11 mm diameter. Solid or stranded wire connections accept 2x (0.25 to 2.5 mm²).","metaTitle":"Siemens 3RT1075-2XJ46-0LA2 SIRIUS Contactor, S12, 72 VDC Coi","metaDescription":"Siemens SIRIUS contactor 3RT1075-2XJ46-0LA2, size S12, 72 VDC coil, screw fixing, 225 mm depth.
