Coil for the S6 frame — what it fits
The 3RT5955-5AC31: This is a SIRIUS-branded magnet coil, designated as a withdrawal coil for the modular S6 contactor system. It is the replaceable coil assembly that pulls the contactor armature in, so when the coil fails or the voltage needs changing, you swap this part rather than the whole contactor.
Because the lifecycle stage is current, this coil is sourced through authorized Siemens distribution.
