Mocotech electronic variable frequency soft starter are versatile and powerful and can be used for special process-related applications, e.g. to avoid torque peaks or water hammer effects. For the first time ever the soft starter can increase the breakaway torque of the motors during start-up through a controlled frequency reduction.
The common draw-out chassis for power stacks with mains and bypass contactors is unique in the world in terms of interchangeability and easy access and maintenance.
The draw-out chassis increases the availability for our custumors. The starter can be installed as stand-alone or as part of a series with a common bus bar system. It offers unrivalled functionality, security and variety while using less space.
