The Siemens SIRIUS 3RT1924-5AN61 is a replacement magnet coil for Size S0 contactors in the SIRIUS family. The operating range spans 0.8 to 1.1 times the rated control supply voltage at 50 Hz, meaning the coil reliably picks up and holds across a 160–220 V AC window at 50 Hz.
This part is flagged as a phased-out product. The official Siemens successor is the 3RT2924-5AN61, also a SIRIUS Size S0 magnet coil.
This coil mounts into the Size S0 contactor frame via the standard screw-terminal interface. Keep the original packaging for the replacement coil until the swap is verified; coil returns are straightforward if the part is unused and the packaging is intact.
