1. INTRODUCTION
This chapter will introduce the VS65 Medium and High voltage solid starter series, describing their
appearance, functions and operations. We recommend that new users read this chapter and acquire an
overall understanding before operating the soft starter.
1.1. Overview
A complete VS65 includes: main circuit-breaker, control transformer, control module, silicon
controlled module, motor protecting module, and high-voltage vacuum bypass contactor. The soft
starting part includes: control module, control transformer, silicon controlled module, and high-voltage
vacuum bypass contactor.
