The Siemens 3RT1054-2XF46-0LA2 is a SIRIUS power contactor in the Size S6 frame, designed for motor switching and resistive loads in industrial control panels. It carries a 110 VDC coil and is rated for AC-3 duty at up to 1000 switching cycles per hour, with AC-4 at 130 cycles/h for plugging or inching applications. The 110 VDC coil pull-in and drop-out timing runs 80 to 90 ms at rated voltage, with an arcing time of 10 to 15 ms. The contactor mounts via screw fixing to a vertical surface and can be rotated ±90° or tilted ±22.5° front-to-back for tight panel layouts. Operating temperature range is -40 to +70 °C, with storage from -55 to +80 °C, making it suitable for unheated enclosures or outdoor-adjacent installations. The auxiliary switch is included on the unit.
Mounting & Clearance
The 172 x 120 x 170 mm (H x W x D) contactor requires minimum clearance around the enclosure: 10 mm upwards, 10 mm downwards, 20 mm forwards, and 10 mm at the side. The single 9 mm mounting hole matches standard M8 hardware. Solid and stranded wire terminations accept 2x 0.25 to 2.5 mm² per clamp — typical for control wiring in a Size S6 panel.
