Product details

The Siemens 3RA2426-8XF32-2AC2 is a SIRIUS contactor assembly purpose-built for star-delta (wye-delta) motor starting. The assembly ships with three contactors: two 3RT2027-2AC20 units for the line and star legs, and one 3RT2026-2AC20 for the delta leg. The supplied RS assembly kit (3RA2923-2BB2) ties them together on a common mounting base.

Mounting and wiring — DIN rail, spring terminals

Main current circuit uses spring-loaded terminals; auxiliary and control circuits also use spring-loaded terminals. AWG main contacts accept 1x (18 … 8).

Frequently asked questions

What is the closest pin-compatible alternative to 3RA2426-8XF32-2AC2?

The assembly uses three specific contactors (3RT2027-2AC20 and 3RT2026-2AC20) and a dedicated RS kit — any replacement would require a different combination of components.
