Reduced Current Starting for Industrial Motors

Star delta starters such as the Lovato SDSI15415 reduce the inrush current drawn during motor startup by initially connecting motor windings in a star configuration before automatically switching to delta operation. This helps minimise voltage dips, mechanical stress and thermal loading during startup.

The integrated overload relay protects motors against excessive current conditions while the built-in isolator improves maintenance safety and operational control. Its IP65-rated enclosure provides dependable protection against dust and water ingress in demanding industrial environments.

Typical Applications

• Industrial pumps and water treatment systems.
• Compressors and refrigeration equipment.
• Conveyor and material handling systems.
• Ventilation and HVAC installations.
• Industrial processing machinery.
• OEM automation and motor control systems.
