SIRIUS 3RT2516-1XF40-0LA2 — Size S00 Contactor with 72-125 V DC Coil
The Siemens SIRIUS 3RT2516-1XF40-0LA2 is a Size S00 contactor rated for a 72-125 V DC coil. It carries screw-type terminals for the magnet coil and includes an auxiliary switch. The contactor snaps onto a 35 mm DIN rail per EN 50022, or can be screw-mounted. Panel clearance: 10 mm upwards and forwards, 6 mm at the sides, and 10 mm downwards. At 73 mm deep, 45 mm wide, and 70 mm tall, it fits standard enclosure layouts without surprises.
Ratings and What They Mean for Fit
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.
Wiring and Mounting
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. Mounting position is flexible: +/-180° rotation on a vertical surface, can be tilted forward/backward by +/-22.5° on vertical, or mounted standing on a horizontal surface. Operating temperature range is -40 to +70 °C, storage -55 to +80 °C — fine for most indoor industrial environments.
