Star-Delta Starter Motor Control Panel

Optimize Your Motor Starting, Enhance Protection, and Ensure Reliability

The Star-Delta (Wye-Delta) Starter Motor Control Panel is an essential solution designed for the efficient and safe starting of large three-phase squirrel cage induction motors. By reducing high inrush currents during startup, our panels minimize mechanical stress on the motor and connected equipment, prevent voltage dips in the power supply, and extend the overall lifespan of your machinery.

Engineered for robust performance in demanding industrial environments, our pre-wired, pre-tested control panels offer a complete, reliable, and compliant solution for your motor control needs.

Key Features & Advantages:

• Reduced Inrush Current: Implements a smooth, two-stage starting sequence (Star configuration then Delta) to significantly lower the starting current, protecting both the motor and the power grid.
• Enhanced Motor Protection:
  • Integrated Thermal Overload Relay: Adjustable bimetallic or electronic relay provides crucial protection against motor overheating due to sustained overcurrent conditions.
  • Short-Circuit Protection: Equipped with high-rupturing capacity (HRC) fuses, Miniature Circuit Breakers (MCBs), or Moulded Case Circuit Breakers (MCCBs) for immediate response to fault currents.
  • Optional Protections: Can include single phasing prevention, phase reversal protection, under/over voltage protection, and earth fault protection.
• Robust & Durable Enclosure:
  • Constructed from high-grade industrial sheet steel (MS) with powder coating or Glass Reinforced Polyester (GRP) for superior corrosion resistance and longevity.
  • Available with various Ingress Protection (IP) ratings (e.g., IP54, IP55, IP65) to shield internal components from dust, moisture, and environmental hazards.
• High-Quality Components: Utilizes premium-grade contactors, overload relays, timers, and control components from reputable manufacturers to ensure maximum reliability and extended service life.
• User-Friendly Interface:
  • Clearly labeled push buttons (Start, Stop, Reset) and selector switches (Auto/Manual, Local/Remote).
  • Visual indicators (LED lamps) for Power ON, Motor RUN, and TRIP status for quick fault identification.
• Automatic & Manual Operation: Features an adjustable electronic or pneumatic timer for automatic Star-Delta transition, with options for manual override.
• Pre-Wired & Tested: Each panel is factory-assembled, wired, and rigorously tested to relevant industry standards, minimizing installation time and reducing on-site wiring errors.
• Compliance: Designed and manufactured in adherence to international standards such as IEC 60947, IS 13947, and CE directives, ensuring safety and performance.
• Customization Options: Available with various motor power ratings, supply voltages, control schemes, and additional features to meet specific application requirements.

Benefits for Your Operations:

• Extended Motor Life: Reduces thermal and mechanical stress on the motor windings and bearings during startup.
• Reduced Maintenance Costs: Less wear and tear on motors and driven equipment, leading to fewer breakdowns and lower repair expenses.
• Improved System Stability: Prevents excessive voltage dips on the supply line, safeguarding other sensitive equipment connected to the same grid.
• Enhanced Safety: Comprehensive protection features safeguard personnel and equipment from electrical faults.
• Energy Efficiency: Optimizes power consumption during the critical startup phase.
• Reliable Performance: Built for continuous, trouble-free operation in harsh industrial settings.
