DOL & Star Delta Starters

Electric motors are the moving force behind countless industrial and commercial operations, powering machinery, HVAC systems, and more. To ensure these motors operate efficiently and have a prolonged lifespan, it's crucial to manage their starting and stopping mechanisms effectively. This is where DOL (Direct-On-Line) and Star Delta Starters come into play. DOL starters provide a simple and cost-effective solution for initiating small to medium-sized motors by applying full voltage directly, making them ideal for applications requiring high starting torque. In contrast, Star Delta Starters are engineered for larger motors, reducing the initial inrush current and mechanical stress by initially connecting the motor windings in a star configuration before switching to delta for regular operation. 

Why DOL & Star Delta Starters are So Important?

  • Motor Longevity: Extends the lifespan of motors by reducing operational stress.
  • Regulatory Compliance: Meets UK electrical standards and safety regulations.
  • Operational Efficiency: Enhances system performance and reduces energy consumption.
  • Downtime Minimisation: Prevents motor failures and reduces maintenance needs.

Discover Our Selection of Premium DOL & Star Delta Starters

  • DOL Starters: Ideal for small to medium motors requiring full voltage start.
  • Star Delta Starters: Suited for large motors to reduce starting current.
  • Auto-Transformer Starters: Provide voltage reduction during start-up.
  • Soft Starters: Offer gradual increase of voltage for smooth start-ups.
