The star-delta combination SIRIUS 3RA24 is designed for gentle starting of three-phase asynchronous motors. It is a tested and factory pre-assembled combination of three contactors 3RT2, which are pre-wired and mechanically and electrically interlocked. The included function module with integrated control logic and time setting replaces the entire wiring in the control circuit.

These combinations are climate-proof, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. 3RA24 star-delta combinations are available with AC and DC actuation in sizes S00 to S3. They are offered in screw and spring-cage connection technology for mounting on top-hat rails or screw fastening. Variants for connection to IO-Link or AS-Interface are also available.

3RT2 contactor accessories are standardized for all sizes and can also be used for contactor combinations. The 3RA24 star-delta combinations replace the tried-and-tested 3RA14 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
