420 V AC/DC coil for S6 contactor frames
The 3RT5955-5AV31: This is the magnet coil assembly for the Siemens SIRIUS S6 modular contactor system — not a full contactor, but the replaceable coil that drives the contactor armature. Rated 420 V on DC, 50 Hz, and 60 Hz control supplies, so it covers global panel builds without swapping coils between regions. AC/DC control supply voltage type means it accepts both rectified DC buses and direct AC control transformers — no need to match the control architecture.
Part of the Siemens SIRIUS family, so it shares the modular mounting and wiring ecosystem with the S6 contactor base units.
