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 3RT2 contactors that are pre-wired and mechanically and electrically interlocked. The included function module with integrated control logic and time setting replaces the complete wiring in the control circuit.

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

The accessories of the 3RT2 contactors are uniform for all sizes and can also be used for the contactor combinations. The 3RA24 star-delta combinations replace the proven 3RA14 series. Simple, efficient, always up-to-date - the SIRIUS modular system. EAN: 4011209838642.
