Further Details:
Star-Delta Combination, AS-i AC-3, 55 kW/400 V, ACDC 20-33 V, 3-pole, Size S2, Screw Connection, Electrical and Mechanical Locking, 3 S + 3 Ö 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 3RT2 contactors that are already wired and mechanically and electrically locked. The included function module with integrated control logic and timing 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 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 system modular concept.
