The manufacturer supplies 500kW one control one soft start cabinet with external side AC

 
summary:
The soft start control cabinet mainly reduces the starting current of the motor, reduces the distribution capacity, avoids the investment of capacity increase, reduces the starting stress and prolongs the service life of the motor and related equipment
With a variety of starting modes and a wide range of current and voltage settings, it can adapt to a variety of load conditions
It can be widely used in loads such as fans, water pumps, conveying and compressors

This series of soft start is equipped with main circuit incoming circuit breaker and bypass contactor, which is used to realize multiple control and protection of motor
At the same time, there are start and stop buttons, operation, stop, fault indication and reserved remote control contacts
Remote control contacts include start stop input contacts, operation output contacts, fault output contacts (all passive relay contacts), and computer communication interface RS485 for upper computer control and management
