1. INTRODUCTION
The VS65 Medium Voltage Soft starter has been designed to start, stop, protect and control medium
voltage AC motors. The VS65 integrates as standard SCR stacks, Snubber circuit, trigger circuit, line and
bypass vacuum contactors, fiber optics interconnections and control board, and a easy user interface, that
make the VS65 MV Soft starter the most complete, reliable and safety soft starter.
Additionally, its modular design permits to integrate additional features such as fuses, ground fault
monitoring relay, metal-clad systems, circuit breakers, etc.
