Product details

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.

Frequently asked questions

Where can I buy 3RT2325-1BW40 and how do I get a price?

This part is sourced and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time through our independent distribution network.

What is 3RT2325-1BW40's listed depth?

The depth is 107 mm, with a width of 60 mm and height of 85 mm, fitting the S0 frame size.

What wire sizes does the screw terminal accept?

Solid conductors: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). Stranded conductors: 1 to 10 mm².

Will 3RT2325-1BW40 drop into a panel specified around 3RT2026-1BB40-0UA0 without rewiring?

Both are SIRIUS S0 contactors with similar DIN rail mounting, but the 3RT2325-1BW40 uses a 48 VDC coil and screw terminals, while the 3RT2026-1BB40-0UA0 may differ in coil voltage and terminal type. Verify coil voltage compatibility and terminal wiring before substitution.
