Efficient Reduced-Current Motor Starting

Star delta starters are commonly used where large induction motors require reduced startup current compared with direct-on-line starting. By initially connecting the motor windings in a star configuration before switching to delta operation, the starter helps reduce electrical loading and mechanical stress on connected systems.

The IMO MC-Y series is designed for industrial automation and OEM machine-building applications requiring dependable operation, simplified panel integration and long-term reliability. The pre-wired construction and compact DIN rail mounting arrangement help reduce installation time and simplify commissioning.

Typical Applications

• Industrial pumps and water systems.
• Compressors and HVAC equipment.
• Conveyor and material handling systems.
• Industrial fans and ventilation systems.
• Processing and packaging machinery.
• OEM automation systems and control panels.
