Combining convenience and innovation, the SSW900 is the right choice for a complete motor protection and
start/stop control. Developed for industrial use, the new line of soft-starters allows easy and simple access
to the configuration settings and application data. Using a well-structured menu interface, the SSW900 line
provides an unprecedented experience of interactivity with the user, allowing adjustments and configurations
with online parameter help right on the Keypad. In addition, event logs with date and time & set up assistant
are available. All models of SSW900 soft starter have built in AC1 bypass, which contributes to extending the
life of the soft starter, optimizing space, and reducing heat dissipation inside electric panels.
