Consumer branch without fuse, direct start AC 400 V, size S2 35...45 A AC/DC 20 ... 33 V screw connection for mounting on DIN rail (also meets assignment type 1) assignment type 2, Iq = 100 kA 1S+1Ö (contactor) with integrated wiring. The SIRIUS 3RA21 direct starter is designed for controlling and starting motors. The 3RA21 direct starter is a tested and factory pre-assembled combination of a circuit breaker 3RV2 and a contactor 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 3RA2 consumer branches are available with AC and DC actuation in sizes S00, S0, and S2 with setting ranges from 0.14 to 65 A. They are offered in screw and spring 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 3RA21 consumer branches replace the proven series 3RA11. Simple, efficient, always up to date - the SIRIUS system modular concept.
