Axpert- CSS Alpha

This is the highest value product for applications where "across-the-line" starting capabilities are not required.

An AC-1 "Run-Rated" Bypass contactor is provided standard. Once the softstarter gets the motor “up-to-speed”, the motor is switched over to the bypass contactor and runs “across-the-line.”

The soft starter still monitors full operation of the AC motor and provides complete diagnostic protection.
