Tips: Soft Starter vs Variable Frequency Drive

Not all soft starters use a simple reduced voltage principle. For a number of years now, advanced soft starters (including the units manufactured by Gozuk), have used 'torque control' that produces a far better starting and stopping characteristic. While variable frequency drives (VFD) produce excellent soft starting and stopping functions (sometimes with extremely low starting current), they are expensive solutions if variable speed is not required - particularly on large applications. Also, the skill level required to 'correctly' commission variable frequency drives is far greater than it is for soft starters. They both have their place and as a supplier and systems integrator for both technologies, we have to be smart enough to know which one to recommend to our customers.

Bypass contactor
The bypass contactor is a must, it used to switching on/off the motor before and after starting period, so can limit the motor inrush/surge current.
Don't provide, but you can get it locally, not an issue and Not expensive!
If you tell us about your motor rated current and voltage, we shall inform you what rating you should purchase.

Bypass contactor
Can you explain what is the purpose of bypass contactor when using your soft starter? Can this soft starter be installed and used without bypass contactor? If this soft starter must have this bypass contactor KM , do you guys sell those contactors? If you do how much do they cost?
