The SIRIUS 3RV29 infeed system is the convenient solution for infeed and distribution whenever you need to reliably supply a number of motor starter protectors or completecombination starters with power. You will find time-saving spring-type terminals in sizes S00 and S0.

The 3RV29 infeed system is based on a basic module complete with a lateral incoming supply unit (three-phase busbar with infeed). Expansion modules (three-phase busbars for system expansion) are available for extending the system. The individual modules are connected via an expansion plug. The electrical connection between the three-phase busbars and the motor starter protectors is implemented through plug-in connectors. The complete system can be mounted on a TH35 standard mounting rail to IEC60715, and can be expanded as required up to a maximum current carrying capacity of 63 A.
