It uses spring-loaded connection technology for the coil terminals — no screwdriver needed on the control wiring, which speeds panel assembly. The holding power draw at 50 Hz is 0.8... 1.1 VA, so it loads the control transformer lightly once the contactor pulls in. The 3RT1934-5AH22 is marked as a phased-out product. The official successor is the SIRIUS 3RT2 series coil. ## Panel Integration & Fit This coil mounts directly onto the SIRIUS Size S2 contactor frame. If you are replacing a failed coil on an existing SIRIUS S2 contactor, check the contactor's frame size marking. The 3RT1934-5AH22 fits only Size S2 frames; it will not physically mate with S0 or S00 contactors.","metaTitle":"Siemens 3RT1934-5AH22 SIRIUS Magnet Coil, 48 V AC 50/60 Hz","metaDescription":"Siemens 3RT1934-5AH22 SIRIUS magnet coil for Size S2 contactors, 48 V AC 50/60 Hz, spring-loaded terminals.
