Soft Starters

Industrial Soft Starters for Motor Control Applications

Industrial soft starters are designed to reduce inrush current and mechanical stress during motor startup. By gradually ramping voltage to the motor, soft starters provide smoother acceleration, improved equipment protection, and longer motor life in demanding industrial environments.

Soft starters are commonly installed in motor control panels, pumps, conveyors, compressors, HVAC systems, and other industrial machinery where controlled startup is required. They help minimize voltage dips, protect mechanical components, and reduce electrical stress on motors and power systems.

Common applications

  • Pumps and water treatment systems
  • Industrial conveyor systems
  • Compressors and HVAC equipment
  • Fans and ventilation systems
  • Heavy industrial motor startup control
