Main contacts are rated for a range of DC loads: 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, 2 A at 500 V, 1 A at 690 V, and 7.6 A at 480 V / 9 A at 600 V for AC loads. The 45 mm wide body mounts on a 35 mm DIN rail (screw and snap-on) and requires 10 mm clearance upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side for proper ventilation and arc containment. ## Terminal wiring Spring-type terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm².","metaTitle":"Siemens SIRIUS 3RT2016-2XJ42-0LA2 Contactor, DC Coil, 45 mm","metaDescription":"Siemens SIRIUS 3RT2016-2XJ42-0LA2 contactor, size S00, 72 V DC coil, spring-type terminals, 45 mm wide.

However, the 2XJ42 uses spring-type terminals while the 1AK22 uses screw terminals, so the wiring method differs. Check that the conductor sizes match the spring terminal ranges."},{"question":"What compliance documentation does this brand provide for 3RT2016-2XJ42-0LA2?","answer":"Siemens SIRIUS contactors typically carry UL, CSA, CE, and RoHS compliance documentation.
