It's the control-side component that pulls in the contactor armature — no coil, no switching. This is a phased-out product; the official successor is the SIRIUS 3RT2 series. The coil operates on AC control voltage only — 220 V at 50 Hz, 240 V at 60 Hz. The voltage tolerance band is 0.8 to 1.1 times the rated value, so the coil holds in reliably down to about 176 V AC and picks up cleanly up to 264 V AC. That's a standard margin for industrial control transformers with typical line sag. The screw terminals match the Size S2 contactor base; no adapter needed for the existing wiring.","metaTitle":"Siemens 3RT1934-5AP61 SIRIUS Magnet Coil, AC 220V 50Hz / 240","metaDescription":"Siemens 3RT1934-5AP61 SIRIUS magnet coil, 220V AC 50Hz / 240V AC 60Hz for Size S2 contactors.
