Product details

SIRIUS S0 contactor — 110 VDC coil, spring terminals

The Siemens 3RT2326-2BF40 is a size S0 contactor from the SIRIUS product brand. It carries a 110 VDC coil with spring-type terminals.

Termination and wiring details

The coil connection uses spring-type terminals. The main contact terminals accept solid conductors: 2x (0.5 to 2.5 mm²) or stranded 1 to 10 mm². The auxiliary switch terminals accept 2x (0.5 to 2.5 mm²) solid or stranded. Strip length for spring terminals is typically 8 to 10 mm — no screw torque to check, but verify the ferrule is fully seated to avoid intermittent contact under vibration.

Frequently asked questions

What are the key dimensions of 3RT2326-2BF40?

Depth is 107 mm, width is 60 mm, height is 102 mm. Minimum clearance: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the side.

What wire sizes does the 3RT2326-2BF40 accept?

Main contacts accept solid 2x (0.5 to 2.5 mm²) or stranded 1 to 10 mm². Auxiliary switch terminals accept 2x (0.5 to 2.5 mm²) solid or stranded. All terminals are spring-type.
