The Siemens 3RT2325-1BW40 is a SIRIUS S0 contactor with a 48 VDC coil and screw-type terminals.
DC Switching Ratings
This contactor is rated for DC switching across a range of voltages: 10 A at 24 V, 2 A at 48 V, 6 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 10 A at 230 V, 3 A at 400 V, 2 A at 500 V, 0.1 A at 600 V, and 1 A at 690 V. These ratings define the DC load-breaking capability at each voltage level — match your circuit voltage and load current to the appropriate row.
The screw-type terminals accept solid conductors of 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²), and stranded conductors from 1 to 10 mm².
