SIRIUS 3RA22 reversing starter for protecting and starting motors. The 3RA22 reversing starter is a tested and factory pre-assembled combination of a circuit breaker 3RV2 and two contactors 3RT2, which are already pre-wired and mechanically and electrically connected. They are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. The consumer branches 3RA2 are available with AC and DC actuation in sizes S00, S0, and S2 with adjustable ranges from 0.14 to 65 A. They are offered in screw and spring terminal connection technology for mounting on DIN rail, screw fastening, and mounting on 60 mm busbars. Additionally, we provide over 40,000 other tested combinations of individual devices for protecting, switching, and starting various applications up to 630 A. All accessories for circuit breakers 3RV2 and contactors 3RT2 are uniform across all sizes and can also be used for the consumer branches. The optional power supply system SIRIUS 3RV29 (for S00 and S0) significantly reduces wiring effort. The consumer branches 3RA22 replace the proven series 3RA12. Simple, efficient, always up to date - the SIRIUS system modular concept.
