The 3RA24 star-delta combination is a tested and factory-assembled combination of three 3RT2 contactors that are already fully wired and mechanically and electrically interlocked. The function module also included with integrated control logic and time setting replaces the entire wiring in the control circuit. They 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 operation in sizes S00 to S3. They are offered with screw and spring-loaded connection technology for mounting on top hat rails or screw fastening. Variants for connection to IO-Link or AS-Interface are also available. The accessories for the 3RT2 contactors are the same for all sizes and can also be used for the contactor combinations. The 3RA24 star-delta combinations replace the tried-and-tested 3RA14 series . Simple, efficient, always up-to-date - the SIRIUS modular system.
