It's the replaceable solenoid that pulls the contactor armature in and holds it closed — when this coil fails or the voltage changes, you swap the coil, not the whole contactor. Rated for 200 V AC at 50 Hz and 220 V AC at 60 Hz, with a holding-power draw between 0.8 and 1.1 VA (the range covers the manufacturing tolerance across the coil population). ## Lifecycle reality — phased out, successor exists This part is marked as a phased-out product. The official successor is the SIRIUS 3RT2 series. For new builds or BOM freezes, plan to qualify the 3RT2 replacement coil and verify the mounting and electrical fit for your specific Size S2 contactor. The part carries the Siemens SIRIUS brand and is designed for panel integration via screw terminals on the contactor coil connection.","metaTitle":"Siemens 3RT1935-5AN61 SIRIUS Magnet Coil, 200 VAC 50/60 Hz","metaDescription":"Siemens 3RT1935-5AN61 SIRIUS magnet coil for Size S2 contactors. 200 VAC 50/60 Hz.
