The DC coil operates from 72 V to 125 V DC — a common control voltage range in 110 V DC substation or industrial control circuits. The contactor's main contacts are rated for switching loads at various voltages: 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, 7.6 A at 480 V, 2 A at 500 V, and 9 A at 600 V. At 230 V, the rating is 1 hp, which tells you it can handle a typical single-phase motor load at that voltage. The AC-4 maximum switching frequency is 250 operations per hour, so it's suited for occasional jogging or inching, not continuous plugging duty. Mechanical life is 30 million cycles typical — the coil and armature will outlast most applications. Solid or stranded wire termination: accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² conductors. The screw-type coil terminals are straightforward for panel wiring.","metaTitle":"Siemens 3RT2516-1XF40-0LA2 SIRIUS Contactor, 72-125 V DC Coi","metaDescription":"Siemens SIRIUS 3RT2516-1XF40-0LA2 contactor, size S00, 45 mm wide, 73 mm deep. 72-125 V DC coil, screw terminals, auxiliary switch.
