It's the replaceable coil assembly — the part that pulls the contactor in and holds it closed — not the full contactor itself. If you're swapping a failed coil on a S12 frame and the nameplate says 420 V AC/DC, this is the drop-in. The control supply voltage type is AC/DC, meaning one coil covers both worlds. That simplifies spares: one part number for a 420 V line, whether it's a VFD DC bus or an AC control transformer.","metaTitle":"Siemens 3RT5975-5AV31 SIRIUS Magnet Coil, 420 V AC/DC, Size","metaDescription":"Active-production Siemens SIRIUS magnet coil for size S12 contactors. 420 V AC/DC coil voltage.
