Reduced Current Starting for Industrial Motors

Star delta starters such as the Lovato SDSI11415 reduce the inrush current drawn during motor startup by initially connecting the motor windings in a star configuration before switching to delta operation. This helps reduce voltage dips, mechanical stress and thermal loading during startup.

The integrated overload relay helps protect motors against excessive current conditions while the built-in isolator improves maintenance safety. Its IP65-rated enclosure ensures reliable performance in industrial environments exposed to dust and moisture.

Typical Applications

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