For highly efficient power distribution
The SIRIUS 3RA6 compact starter makes use of a fully pre-wired infeed system with screw-type or spring-loaded connections in the main circuit. The PE bar is already integrated so that the motor cable can be connected direct to the power distribution system thus reducing engineering overhead and space and wiring requirements.
SIRIUS circuit-breakers can also be integrated via a special adapter into the SIRIUS 3RA6 infeed system. If you wish to combine the SIRIUS 3RA6 infeed system with the latest SIRIUS 3RV19 infeed system, you simply need the optional expansion plug for quick and easy connection.
The associated 3RA6 infeed system forms an ideal basis for uniform and convenient power infeed and distribution.
