Additional Details: Star-Delta combination with AS-i, AC-3, 90 kW/400 V, AC/DC 20-33 V, size S3, screw connection, electrical and mechanical interlocking 3S+3Ö, integrated varistor. The SIRIUS 3RA24 Star-Delta combination is designed for the soft starting of three-phase asynchronous motors. The 3RA24 Star-Delta combination is a tested and factory pre-assembled combination of three 3RT2 contactors that are already pre-wired and mechanically as well as electrically interlocked. The included function module with integrated control logic and timing replaces the entire wiring in the control circuit. They are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready.

3RA24 Star-Delta combinations are available in sizes S00 to S3 with AC and DC actuation. They are offered in screw and spring cage connection technology for mounting on DIN rails or for 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 proven 3RA14 series. Simple, efficient, always up to date - the modular SIRIUS system.
