Combination Starters

SIEMENS SIRIUS 3RA1/3RA2 combination starters consist of a pre-wired and mechanically connected 3RV MSP and 3RT contactor, allowing for quick installation of a complete branch circuit. The non-reversing or reversing assemblies come on a fast bus mounting shoe or as a panel mount version. The SIRIUS 3RA6 compact starters provide the functionality of an MSP, contactor and electronic overload relay in one easy to install housing, saving wiring and installation time. Available in both non-reversing and reversing starters that can be mounted on a fast bus shoe. The SIRIUS 3RA6 infeed system further saves line side wiring in multiple motor panels.
