The main contacts are rated 20-12 A, and the contactor handles AC-4 duty up to 250 operations per hour. ## Coil and switching behaviour The DC coil picks up at 0.7 times the rated voltage and drops out at 1.25 times, giving a clean pull-in and release. Switching time at DC is 25-45 ms, and arcing time runs 10-15 ms. Inrush current peaks at 1.1 A, so the control transformer or DC supply needs to handle that momentary load without sagging. Dimensions are 45 mm wide, 70 mm high, 73 mm deep. ## Switching capacity across voltages The contactor's rated operational current varies with voltage and duty. At 24 V DC it handles 10 A; at 48 V and 60 V it drops to 2 A; at 110 V it's 1 A; at 125 V it's 0.9 A; at 220 V it's 0.3 A; at 230 V it's rated 0.75 hp; at 400 V it's 3 A; at 480 V it's 4.8 A; at 500 V it's 2 A; at 600 V it's 6.1 A. These numbers define the load it can switch in a given circuit voltage — match the column that fits your application.","metaTitle":"Siemens SIRIUS 3RT2015-2XF42-0LA2 Contactor, 72-125 V DC Coi","metaDescription":"Siemens SIRIUS 3RT2015-2XF42-0LA2 contactor, size S00, 72-125 V DC coil, spring-type terminals.
