The 3RT1456-2XB46-0LA2: The 24 V DC coil is the main selection gate — if your control voltage is 24 VDC, this contactor drops right in. Coil pickup and dropout characteristics are standard for a DC-operated SIRIUS frame, so expect clean pull-in even with long control wiring runs. Size S6 means this contactor handles the higher current ranges in the SIRIUS family — it's the frame size you'd spec for motor loads above what the S0–S3 frames carry. The 172 x 120 x 170 mm envelope (height x width x depth) tells you the panel cutout and clearance needed. Mounting is screw fixing, with the contactor rotatable ±90° on a vertical surface and tiltable ±22.5° front-to-back. That flexibility helps when you're laying out a dense panel and need to orient the contactor to clear busbars or duct.
This contactor belongs in motor control centers and distribution panels, switching three-phase induction motors, resistive loads, or capacitor banks. The SIRIUS series is Siemens' workhorse line for standard industrial switching up to the S6 frame rating.
No last-time-buy or phase-out notice applies. For a procurement planner, that means no urgent BOM freeze action needed; you can order this part against an RFQ through standard distribution.
