This is the replacement coil for the SIRIUS 3RT1 contactor frame — the one you pull when the original coil fails or when you're rebuilding a panel that needs a 220 V AC coil drop-in. ## Coil operating range and what it means on the line The coil's operating range is 0.8 to 1.1 times the rated voltage at 50 Hz — so on a 220 V AC nominal supply, it picks up and holds reliably between roughly 176 V and 242 V. That's a standard ±20% tolerance band for industrial contactor coils; if your control transformer sags below 176 V under load, this coil drops out before the main contacts start chattering. The same 0.8...1.1 range applies at 60 Hz, keeping the hold-in consistent across line frequencies. ## Lifecycle reality — phased out with a clear successor This part is flagged as a phased-out product. The official successor is the SIRIUS 3RT2 series — same Size S2 footprint, same 220 V AC coil voltage, but built on the newer platform. If you're holding a BOM line that specifies 3RT1934-5AN22, the 3RT2 equivalent is the drop-in replacement for new builds. ## Termination and panel fit Spring-loaded connection technology — no screwdriver needed for the coil terminals, just strip and push. The coil mounts onto the SIRIUS Size S2 contactor body via the standard snap-on interface; no tools required for the mechanical attachment either.","metaTitle":"Siemens 3RT1934-5AN22 SIRIUS Magnet Coil, 220 V AC, Phased O","metaDescription":"Siemens SIRIUS 3RT1934-5AN22 magnet coil for Size S2 contactors. 220 V AC 50/60 Hz, spring-loaded terminals.
