Load feeder without fuse, direct starting AC 400 V, size S00 2.20...3.20 A DC 24 V spring-loaded terminal for standard rail mounting (also meets coordination type 1) coordination type 2, Iq = 150 kA 1S (contactor) SIRIUS 3RA21 direct starter for protecting and starting motors.The 3RA21 direct starter is a tested and factory-preassembled combination of a 3RV2 circuit breaker and a 3RT2 contactor, which are already fully wired and mechanically and electrically connected. They are climate-resistant, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4 ready.The 3RA2 load feeders are available with AC and DC operation in sizes S00, S0 and S2 with setting ranges from 0.14 to 65 A. They are available with screw and spring-loaded connection technology for mounting on a standard rail, screw fastening and mounting on a 60 mm busbar. In addition, we offer over 40,000 other tested combinations of individual devices for protecting, switching and starting a wide variety of applications up to 630 A. All accessories for the 3RV2 circuit breakers and 3RT2 contactors are standardized for all sizes and can also be used for the load feeders. The optional SIRIUS 3RV29 feeder system (for S00 and S0) significantly reduces the wiring effort. The 3RA21 load feeders replace the tried and tested 3RA11 series. Simple, efficient, always up to date - the SIRIUS modular system.
