This makes it suitable for smaller motor control applications where a DC control voltage is already available in the panel. ## Dimensions, Wiring, and Clearances The contactor measures 45 mm wide, 70 mm high, and 121 mm deep. That 121 mm depth is the dimension to watch when fitting into shallow enclosures or when back-panel clearance is tight. Spring-type terminals on the coil accept solid conductors from 0.5 to 1.5 mm² (two per terminal), stranded from 0.75 to 2.5 mm² (two per terminal), or a single 4 mm² conductor. ## DC Switching Ratings Across Voltages The main contact DC switching capacity varies significantly with voltage, which is typical for DC load interruption. Key ratings: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 11 A at 480 V, 2 A at 500 V, 11 A at 600 V, and 1 A at 690 V. The higher currents at 480 V and 600 V suggest these are likely AC ratings or a different duty cycle — verify against your specific load type and voltage. The contactor includes an auxiliary switch and has a typical mechanical life of 30,000,000 operations. Maximum switching frequency under AC-4 duty is 250 operations per hour.","metaTitle":"Siemens 3RT2017-2KG42-0LA0 SIRIUS Contactor, S00, DC Coil, 1","metaDescription":"Siemens SIRIUS 3RT2017-2KG42-0LA0 contactor, size S00, DC coil, spring-type terminals.
