Reliable Reduced-Current Motor Starting

Star delta starters are widely used for large industrial motors where direct-on-line starting could result in excessive inrush current and mechanical stress. By initially starting the motor in a star configuration before switching to delta operation, the starter reduces electrical loading and helps protect motors and driven equipment.

The IMO MC-Y series is designed for industrial environments requiring reliable motor control, safe switching and efficient panel integration. The pre-wired open-frame construction reduces installation time while delivering dependable long-term performance in demanding automation and machinery applications.

Typical Applications

• Industrial pumps and water treatment systems.
• Compressors and HVAC installations.
• Conveyor and material handling systems.
• Industrial fans and ventilation equipment.
• Production and processing machinery.
• OEM automation systems and motor control panels.
