Star-delta combination AC-3, 11 kW/400 V, DC 24 V, 3-pole, size S00, screw connection, electrical and mechanical interlock, 3 S integrated. The SIRIUS 3RA24 star-delta combination allows for a gentle start of three-phase asynchronous motors. It is a tested and factory pre-assembled combination of three contactors 3RT2, which are already wired, as well as mechanically and electrically interlocked. The included function module with integrated control logic and time setting replaces the complete wiring in the control circuit. The devices are climate-resistant, globally approved (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. They are offered in screw and spring clamp connection technology for mounting on DIN rail or screw fastening. Additionally, variants for connection to IO-Link or AS-Interface are available. The accessories for the 3RT2 contactors are uniform across all sizes and can also be used for the contactor combinations. The 3RA24 star-delta combinations replace the proven series 3RA14. Simple, efficient, always up to date - the SIRIUS system modular concept.
