Fuseless load feeder, direct starting AC 400 V, size S0 3.50...5.00 A DC 24 V spring-cage connection for 60 mm busbar systems (also fulfils assignment type 1) Assignment type 2, Iq = 150 kA 1S+1Ö (contactor) SIRIUS 3RA21 direct starter for protecting and starting motors.The 3RA21 direct starter is a tested and factory pre-assembled combination of a 3RV2 circuit-breaker and a 3RT2 contactor, which are pre-wired and mechanically and electrically connected. They are climate-proof, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4 ready.3RA2 load feeders are available with AC and DC actuation in sizes S00, S0 and S2 with setting ranges from 0.14 to 65 A. They are available in screw and spring-loaded versions. They are offered in screw and spring-cage connection technology for mounting on top-hat rails, screw mounting and mounting on 60 mm busbars. We also offer over 40,000 other tested combinations of individual devices for protecting, switching and starting a wide range of applications up to 630 A.All accessories for 3RV2 circuit-breakers and 3RT2 contactors are standardised for all sizes and can also be used for load feeders. The optional SIRIUS 3RV29 feeder system (for S00 and S0) significantly reduces the wiring effort, while the 3RA21 load feeders replace the tried-and-tested 3RA11 series.Simple, efficient, always up-to-date - the SIRIUS modular system.
