Direct Online Starter

The Direct Online Starter Panel is designed for the safe, efficient starting of three-phase induction motors by applying full-line voltage directly to the motor terminals. It is one of the simplest and most cost-effective motor-starting solutions, ideal for low- to medium-horsepower motors where high starting current is acceptable.

The panel features short-circuit and overload protection, automatic/manual operation, and user-friendly controls, ensuring reliable operation in demanding industrial and commercial applications.

Manufactured from 16 SWG CRCA sheet steel with powder coating, the enclosure offers durability, corrosion resistance, and a long service life in harsh environments.

  • Operates on 440V AC, 50 Hz AC supply
  • R,Y,B and ON Indication
  • Short circuit and overload protection
  • Automatic and manually operated
  • Easy to operate
  • High Performance
  • Easy installation and connection
