What it is and what it does
The Siemens SIRIUS 3RT2016-2XF41-0LA2 is a size S00 power contactor with a DC coil rated 72-125 V. It switches main contacts rated 20-12 A and includes an auxiliary switch. The coil uses spring-type terminals, and the main circuit accepts solid conductors from 0.5 to 4 mm².
Panel fit and mounting
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 50022. The 45 mm width and 73 mm depth fit standard S00 contactor slots. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. Mounting position is flexible — ±180° rotation on vertical surfaces, ±22.5° tilt forward/backward, or horizontal standing.
Coil and switching characteristics
DC coil picks up at 0.7 x rated voltage and drops out at 1.25 x rated. Dropout delay is 25-45 ms; arcing time is 10-15 ms. Inrush current peaks at 1.1 A. The contactor is rated for 30 million mechanical cycles. Maximum switching rate in AC-4 duty is 250 operations per hour. Operating temperature range is -40 to +70 °C; storage range is -55 to +80 °C.
Comparison with 3RT2016-1AG62
The 3RT2016-1AG62 is the AC coil sibling in the same S00 frame. The 3RT2016-2XF41-0LA2 uses a DC coil (72-125 V) with spring-type terminals, while the 1AG62 uses an AC coil with screw terminals.
