The auxiliary contact block is rated 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 230 V, and 3 A at 400 V — these are the switching capacities for the built-in auxiliary switch, so verify your control circuit voltage against these curves. The main contactor itself carries an AC-3 maximum operating frequency of 1,000 cycles per hour, and AC-4 at 300 cycles per hour; the AC-4 limit matters for plugging or inching duty where the contactor makes and breaks under load more frequently. Arcing time is 10 ms. These numbers govern panel layout — if you're packing contactors tight, maintain those gaps to avoid flashover between phases. The Size S0 footprint (45 mm wide, 102 mm tall, 97 mm deep) fits standard panel layouts. Spring-type coil terminals and screw-type main terminals — no special tooling needed beyond a screwdriver and a ferrule crimper for stranded wire.","metaTitle":"Siemens 3RT2025-2AF00 SIRIUS Power Contactor, Size S0, 24 VD","metaDescription":"Siemens 3RT2025-2AF00 SIRIUS power contactor, Size S0, 24 VDC coil, spring-type terminals, snap-on DIN rail mount.
