This method ensures smooth motor operation and enhances durability.

Features:

  • Suitable for 3-phase induction motors

  • Reduces inrush current and voltage drop during startup

  • Automatic transition from star to delta connection

  • Equipped with thermal overload protection

  • Compact and durable design for industrial environments

  • Easy installation and maintenance

Applications:
Ideal for use in:

  • Industrial machinery

  • Pumps and compressors
