Product details

Sourcing and lifecycle — what it means for your BOM

The Siemens 3RT1054-6XB46-0LA2 is a current-production power contactor in the SIRIUS family. This part is quoted to order against the BOM quantity.

Panel fit: dimensions and mounting details

The 3RT1054-6XB46-0LA2 is a Size S6 contactor with a width of 120 mm, height of 172 mm, and depth of 170 mm. It mounts via screw fixing through a 9 mm diameter hole.

Wiring capacity and termination

That covers common panel wire gauges for a contactor of this frame size. The auxiliary contacts handle lower-current control signals without a separate relay.
