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. ## Environmental range","metaTitle":"Siemens 3RT2325-1BF40 SIRIUS Contactor, 110 V DC, S0 Size","metaDescription":"Siemens SIRIUS 3RT2325-1BF40 contactor, size S0, 110 V DC coil, screw terminals.
