A Thermonic Star-Delta Motor Starter Panel (Flameproof Type)
is designed to safely start and control induction motors in hazardous and
explosive environments. The panel uses a star-delta starting method to reduce
the inrush current during motor starting, ensuring motor protection and system
reliability.
Built with flameproof enclosures certified for hazardous areas, these panels
are suitable for industries where safety against fire and explosion risks is
critical.
Key Benefits of Thermonic Flameproof Star-Delta Panels:
• Flameproof Safety – Certified enclosures for hazardous
zones
• Reduced Inrush Current – Star-delta method ensures safe motor starting
• Motor Protection – Overload, short-circuit, and earth fault protection
• Durability – Heavy-duty construction for industrial environments
• Compliance – Designed as per IS/IEC standards for flameproof equipment
• Customization – Compatible with motors of various HP ratings
Thermonic Flameproof Star-Delta Panels comply with:
• IS/IEC 60079 – Electrical apparatus for explosive gas atmospheres
