It operates on 24 V AC control supply voltage at both 50 Hz and 60 Hz, drawing a holding power range of 0.8... 1.1 A at 50 Hz. This coil uses spring-type terminals for the control circuit, so it snaps onto the contactor without screw terminals — handy when you're swapping a coil in a tight panel and don't want to fish for a screwdriver. It's a direct-fit replacement for the coil on any SIRIUS Size S0 contactor (like the 3RT1026 series) that originally shipped with a 24 V AC coil — same mounting footprint, same DIN-rail integration. ## Does it drop into a panel wired for a 3RT1026-1AB00? Yes — the 3RT1924-5AC22 coil shares the same Size S0 frame and 24 V AC control voltage as the 3RT1026-1AB00 contactor's coil. The spring-type terminal on this coil is a different connection style than the screw terminals on the 3RT1026-1AB00's main circuit, but the coil itself is a direct mechanical and electrical swap for the existing 24 V AC coil in that contactor. No rewiring of the main power circuit needed.","metaTitle":"Siemens 3RT1924-5AC22 SIRIUS Magnet Coil, 24 V AC, 50/60 Hz","metaDescription":"Siemens SIRIUS 3RT1924-5AC22 magnet coil for Size S0 contactors, 24 V AC 50/60 Hz.

For a direct drop-in, the 3RT1026-1AB00 contactor uses the same Size S0 frame and 24 V AC coil voltage — if you need a complete contactor assembly rather than just the coil, that's a functional equivalent in the same SIRIUS family."},{"question":"What is 3RT1924-5AC22's at 50 Hz rating?","answer":"At 50 Hz the coil draws 0.8... 1.1 A at 24 V AC."},{"question":"Will 3RT1924-5AC22 drop into a panel that was specified around 3RT1026-1AB00 without rewiring?","answer":"Yes — the coil is a direct mechanical and electrical swap for the 24 V AC coil in a 3RT1026-1AB00 contactor.
