It includes three contactors: two 3RT2026-2AG20 units and one 3RT2024-2AG20 unit, plus the RS assembly kit 3RA2923-2BB2. The assembly is rated for 15 kW at 400 V AC and 19 kW at both 500 V and 690 V AC, making it suitable for medium-power induction motor loads in pump, fan, and conveyor applications. At 690 V the same assembly handles 19 kW, so it can serve higher-voltage motors in regions where that supply is standard. The 110 V AC coil (50/60 Hz) draws 0.25 A at 50 Hz and 0.28 A at 60 Hz; verify your control transformer can supply that inrush. It occupies the S0 frame size: 135 mm wide, 114 mm high, 171 mm deep. Clearance around the unit: 6 mm upward, forward, downward, and to the side; 0 mm backward (flush to the rail). Spring-loaded terminals on both main and control circuits accept 2x (1... 10 mm²) solid or 2x (0.5... 2.5 mm²) stranded, and 1x (18... 8) AWG on main contacts.","metaTitle":"Siemens 3RA2425-8XF32-2AG2 SIRIUS Contactor Assembly","metaDescription":"Siemens SIRIUS 3RA2425-8XF32-2AG2 star-delta contactor assembly, 15 kW at 400 V, 110 V AC coil, spring terminals.
