The Siemens Digital Industries Star-Delta Combination 3RA2437-8XF32-1AC2 is designed for the soft starting of three-phase asynchronous motors. It features a tested and factory pre-assembled combination of three 3RT2 contactors that are pre-configured and mechanically as well as electrically interlocked. The included function module with integrated control logic and timing replaces all wiring in the control circuit.

These devices are climate-resistant, globally approved, and ready for IE3/IE4. The 3RA24 Star-Delta combinations are available in sizes S00 to S3 with AC and DC actuation. They can be mounted on DIN rails using screw or spring cage connection technology or installed via screw fastening. Variants for connection to IO-Link or AS-Interface are also available.

The accessories for 3RT2 contactors are standardized for all sizes and can be used for contactor combinations. The 3RA24 Star-Delta combinations replace the proven 3RA14 series. Simple, efficient, and always up to date - the modular SIRIUS system.
