The SIRIUS 3RA21 direct starter is designed to protect and start motors. It is a tested and factory pre-assembled combination of a circuit breaker 3RV2 and a contactor 3RT2, which are already wired and mechanically and electrically connected. The devices 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 installation on 60 mm busbars. In addition, 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 the 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 3RA21 replace the proven series 3RA11. Simple, efficient, always up to date - the SIRIUS system modular kit.
