Siemens SIRIUS 3RT5975-5AP31 is a withdrawable magnet coil for size S12 contactors. It accepts 240 V AC/DC control supply voltage.
The 240 V AC/DC rating means this coil drops into any panel where the control transformer or DC supply bus is 240 V nominal. Because it is withdrawable, it pulls straight off the contactor magnet stack — no need to disconnect wiring from the coil terminals if the contactor is already wired through the coil base. That saves minutes per swap on a line-down call.
Deployment context
This coil mounts on a size S12 SIRIUS contactor, which is a DIN-rail or screw-fixed device typical in motor control centers and panel builds. The withdrawable design means the coil can be replaced without removing the contactor from the rail — relevant for tight enclosures where access to the coil terminals is limited.
