It operates on a 110 V AC control supply at 50 Hz, drawing 0.8 to 1.1 A at that frequency. This part is marked as a phased-out product. The official Siemens successor is the 3RT2924-5AF01, a SIRIUS 3RT2-series coil that drops into the same Size S0 contactor frame. No last-time-buy window is stated in the record. ## Integration note for panel builders The coil uses screw terminals for the control wiring, matching the standard SIRIUS S0 contactor terminal arrangement. It mounts directly onto the contactor via the snap-on mechanism — no additional hardware required. The 110 V AC 50 Hz rating means it is intended for European-standard control circuits; verify the control transformer taps before energizing.","metaTitle":"Siemens 3RT1924-5AF01 SIRIUS Magnet Coil, 110 V AC 50 Hz","metaDescription":"Siemens 3RT1924-5AF01 SIRIUS magnet coil for Size S0 contactors.
