The Siemens SIRIUS 3RT1924-5AN62 is a magnet coil for Size S0 contactors, rated 200 V AC at 50/60 Hz and 220 V at 60 Hz. It uses a spring-type terminal for the control wiring. This is a phased-out product; the official successor is the SIRIUS 3RT2 series.
What This Coil Fits
This coil is designed for SIRIUS Size S0 contactors. The 200-220 V AC control voltage is a common industrial range for panels fed from a 208-240 V control transformer. The spring-type terminal on the coil makes wiring faster than screw terminals, though it requires a ferrule or solid conductor for a reliable connection. It snaps onto the contactor's magnet system without tools.
