Operating range is 24-34 V DC, with a dropout below the 0.7 initial value factor. Switching the coil takes 25-45 ms at DC; arcing time runs 10-15 ms. For AC switching, the contactor handles 3 A at 400 V, 11 A at 480 V, and 11 A at 600 V rated value. ## Panel integration and clearances The S00 frame measures 45 mm wide, 73 mm deep, and 70 mm high. The spring-type terminals accept 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or 2x 4 mm² solid or stranded wire.","metaTitle":"Siemens 3RT2017-2XB42-0LA2 SIRIUS Contactor, DC Coil 24-34 V","metaDescription":"Siemens SIRIUS 3RT2017-2XB42-0LA2 contactor, Size S00, DC coil 24-34 V, spring-type terminals, 45 mm wide.
