Basic AC Motor Soft Starters

SR35 full-featured solid-state Soft Starters provide many advantages when used instead of electromechanical contactors to control both 1-phase and 3-phase AC induction motors. The SR35 Soft Starters are fully digital and use thyristors on the A and C phases for controlled reduced voltage motor starting and stopping. SR35s have an Automatic Application Setup that fully configures the starter for a specific application with one entry.

• Smaller physical size than equivalent SR55 models
• Reduced starting currents and spikes
• Lower overall costs for new installations, bypass relays built in
• Automatic application setup feature speeds installation by configuring the SR35 for a specific application with one setting
