The 3RT2516-1BM40: This contactor mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 50022, with a width of 45 mm, height of 57.5 mm, and depth of 73 mm. Side-by-side mounting is permitted with 6 mm spacing at the side; zero clearance is allowed upwards, forwards, backwards, and downwards.
Switching Ratings and Duty
For DC switching, the contactor is rated at 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 2 A at 125 V, 0.3 A at 220 V, 10 A at 230 V, 3 A at 400 V, 0.8 A at 440 V, and 0.1 A at 600 V. These are the maximum continuous currents for DC loads at the respective voltages — the arc extinction capability drops as voltage rises, so the 10 A at 24 V is the high-current case, while at 600 V it's limited to 0.1 A. Mechanical life is rated at 30,000,000 operating cycles typical. Maximum electrical switching frequency at AC is 10,000 operations per hour, derated to 1,000 per hour at AC-1 maximum load. Arcing time is 10 to 15 ms; DC switching has a dropout delay of 7 to 13 ms. The coil hold-in voltage range is 0.8 to 1.1 times the rated value (220 V).
Environmental and Mounting
Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. The mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward or backward. Terminal capacity for solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². The auxiliary switch is included as standard.
