MT830 high voltage soft starter Integrated high voltage soft start
cabinet
Product Overview
MT830 high-voltage solid-state integrated soft starter, on the
basis of MT830 soft starter, add a trolley-type vacuum circuit
breaker, integration of high-voltage switchgear functions,
performance is more integrated.
Based on MT830 soft starter, MT830 adds handcart type vacuum
circuit breaker and integrates the functions of high voltage
switchgear, which makes the performance more integrated and stable.
Model MT830 is specially designed for the starting and stopping of
AC motors as running power.
The MT830 is specially designed for the starting and stopping of AC
motor as the running power. It has the features of low starting
current, smooth starting, prolonging the service life of motor and
starting equipment, and so on.
The MT830 is specially designed for the starting and stopping of AC
motors.
Cabinet features
