SIEMENS Star-delta combination AC3, 15/18.5kW /400V AC230V, 50/60Hz, 3-pole S0 – 3RA24258XF321AL2

Star-delta combination AC-3, 15/18.5 kW/400 V AC 230 V, 50/60 Hz, 3-pole, size S0, screw terminal electrical and mechanical interlocking 3 NO + 3 NC integrated SIRIUS 3RA24 star-delta combination for soft starting of three-phase asynchronous motors. The 3RA24 star-delta combination is a tested and factory-assembled combination of three 3RT2 contactors, which are already fully wired and mechanically and electrically interlocked. The integrated function module with integrated control logic and time setting replaces the complete 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-type terminals for mounting on DIN rails or screw fixing. In addition, variants for connection to IO-Link or AS-Interface are available. The accessories for 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.
