The coil's operating range is 0.8 to 1.1 times the rated voltage at 50 Hz, meaning it picks up and holds reliably between roughly 184 V and 253 V on a 230 V nominal line. That's a standard tolerance for AC-operated contactor coils in industrial control panels. ## Lifecycle reality — phased out, successor known This part is flagged as a phased-out product. The official successor is the SIRIUS 3RT2 series coil. If you are maintaining an existing panel that uses the 3RT1935-5AP01, the coil itself is still serviceable through independent distribution, but new designs or BOM revisions should migrate to the 3RT2-series equivalent. ## Fit and integration — what swaps in and what does not The coil is AC-operated only.","metaTitle":"Siemens 3RT1935-5AP01 SIRIUS Magnet Coil, 230 V AC 50 Hz","metaDescription":"Siemens SIRIUS 3RT1935-5AP01 magnet coil for Size S2 contactors, 230 V AC 50 Hz.
