Contactor for Motor and Resistive Load Switching
The Siemens 3RT1456-2XF46-0LA2 is a SIRIUS contactor in size S6, designed for switching motor and resistive loads in industrial control panels. It is rated for 96 A at 480 V, making it suitable for high-current applications such as conveyors, pumps, and compressors. The 110 VDC coil ensures reliable pick-up and drop-out in DC control circuits.
Mounting and Integration
Mounts via screw fixing with a single 9 mm hole. The contactor can be rotated +/-90° on a vertical surface or tilted +/-22.5° forward/back, giving flexibility in tight enclosures. Minimum clearance: 10 mm upwards, 10 mm downwards, 10 mm at the side, and 20 mm forwards. Dimensions: 172 mm height, 120 mm width, 170 mm depth — fits standard panel layouts.
Switching Performance and Auxiliary Contact
Arcing time is 10 to 15 ms; mechanical life is typically 10,000,000 operations. The contactor includes an auxiliary switch (1 NO + 1 NC configuration typical for this series). Maximum switching frequency: 600 cycles/hour for AC-1 duty, 400 cycles/hour for DC-1 duty. For DC switching, the rated current varies by voltage: 6 A at 24 V, 2 A at 48 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V. For AC switching at 230 V it handles 6 A; at 400 V, 3 A; at 440 V, 1.4 A; at 500 V, 2 A.
