This coil is the replacement part for the contactor's electromagnetic actuation — when the coil fails or a panel needs a different control voltage, this is the swap-in component. This part is a phased-out product. The manufacturer's official successor is the SIRIUS 3RT2 series. If you're swapping a failed coil in an existing panel, the spring-cage terminals are faster to re-terminate than screw types, but verify the conductor preparation matches the contactor's wiring spec. The coil draws 0.8... 1.1 A at 50 Hz — that's the holding current once the contactor is picked up. The pick-up inrush is higher but brief; the control transformer or PLC output driving this coil must be rated for the inrush, not just the holding current. At 60 Hz the coil is rated for 220 V, so a 208 V or 240 V control bus is within range. If your panel runs a 230 V control transformer, this coil's 200 V 50 Hz / 220 V 60 Hz rating means it will pull in reliably on the 230 V bus, but verify the thermal margin — sustained overvoltage on the coil reduces service life.","metaTitle":"Siemens 3RT1934-5AN62 SIRIUS Magnet Coil, 200 V AC, 50/60 Hz","metaDescription":"Siemens SIRIUS 3RT1934-5AN62 magnet coil for Size S2 contactors, 200 V AC 50/60 Hz.

However, it is a physically smaller frame (S00 vs S2) and has a different control voltage rating (220 V 50 Hz vs 200 V 50 Hz). It will not drop into a panel wired for the S2 contactor without rewiring the contactor base and verifying the mechanical fit."},{"question":"What is the at 50 Hz rating for 3RT1934-5AN62?","answer":"The coil draws 0.8... 1.1 A at 50 Hz, with a rated voltage of 200 V AC at 50 Hz."},{"question":"What compliance documentation does this part carry?","answer":"The part is a Siemens SIRIUS product.
