It replaces the coil in older SIRIUS 3RT1 contactor assemblies. This part carries a current lifecycle stage but is explicitly marked as a phased-out product. The official successor is the SIRIUS 3RT2 series — meaning if you are designing a new panel or stocking for a new build, you should specify the 3RT2 coil instead. For existing 3RT1 contactors already in the field, the 3RT1935-5AW61 remains the correct replacement coil. The 347 V AC, 60 Hz coil voltage is specific — this is not a 50 Hz coil, and it is not a dual-frequency part. For 50 Hz installations or other voltages, the 3RT2 successor series offers a wider range of coil options. The screw terminal connection and Size S2 mounting pattern mean it drops into the existing contactor yoke without panel rewiring — the mechanical interface is unchanged from the original 3RT1 coil it replaces. No DIN-rail space is consumed; the coil mounts directly onto the contactor magnet system.","metaTitle":"Siemens 3RT1935-5AW61 SIRIUS Magnet Coil, 347 V AC 60 Hz","metaDescription":"Siemens SIRIUS 3RT1935-5AW61 magnet coil for Size S2 contactors, 347 V AC 60 Hz, screw terminal.
