Motor Sarters

Load Feeders for any application

In our SIRIUS range, you will find the right load feeders (for direct, reversing or star-delta (wye-delta) starters) - fused or fuseless - comprising easily combined single units (e.g. by fitting the appropriate function modules to contactors) or as pre-wired and tested complete units with spring-loaded or screw-type connections. More than 40,000 tested combinations cover almost every application case.

The 3RA2 fuseless load feeders consist of the 3RV2 motor starter protector and the 3RT2 electromechanical contactor.

The devices are electrical and mechanically connected using preassembled assembly kits (link modules, wiring kits and standard mounting rail or busbar adapters).
