SIRIUS S0 contactor, 110 V DC coil
The Siemens SIRIUS 3RT2325-1BF40 is a size S0 contactor with a 110 V DC magnet coil and screw-type terminals, designed for screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715.
The S0 frame measures 85 mm high, 60 mm wide, and 107 mm deep, fitting standard panel layouts. The contactor accepts solid or stranded conductors: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²) for auxiliary circuits; main contacts accept stranded 1 to 10 mm². An auxiliary switch block is attachable (2 positions), expanding the contactor's signal feedback capability.
The auxiliary contacts are rated for switching across a wide voltage range: 10 A at 24 V DC, 2 A at 48 V DC, 6 A at 60 V DC, 1 A at 110 V DC, 0.9 A at 125 V DC, 0.3 A at 220 V DC, 10 A at 230 V AC, 3 A at 400 V AC, 2 A at 500 V AC, 0.1 A at 600 V AC, and 1 A at 690 V AC.
