It is the replacement coil for a SIRIUS 3RT1 contactor in the S2 frame — the one you pull out of the cabinet when the original coil fails or the control voltage changes. ## Lifecycle reality — phased out, successor named Siemens lists this coil as a phased-out product. The official successor is the SIRIUS 3RT2 series coil. If you are stocking spares for a panel built around the 3RT1 contactor, this coil is the direct drop-in replacement for the existing coil — but for new builds or BOM revisions, the 3RT2 coil is the current-production path. No last-time-buy window is stated in the available documentation, so sourcing now means independent-distribution channels.","metaTitle":"Siemens 3RT1934-5BD41 SIRIUS Magnet Coil, 42 V DC, Phased Ou","metaDescription":"Siemens SIRIUS 3RT1934-5BD41 magnet coil for Size S2 contactors, 42 V DC, screw terminal.
