Connect With Us
The Thermonic Star-Delta Motor Starter Panel (Flameproof Type) is specially designed for safe starting and control of induction motors installed in hazardous or explosive environments. It operates on a Star-Delta starting principle, which reduces the inrush current at motor start-up and ensures smooth acceleration — protecting both motor and connected equipment.
Constructed with flameproof (FLP) or explosion-proof enclosures certified for Gas Group IIA, IIB, or IIC areas, this panel is ideal for industries such as oil & gas, chemical, paint, refinery, and petrochemical plants. It provides manual and automatic operation, built-in protection, and robust performance even in harsh field conditions.
Thermonic Flameproof Star-Delta Panels are designed and tested to comply with the highest electrical and safety standards:
- 🌐 IS / IEC 60079-1 – Explosive Atmospheres – Flameproof Enclosures
- 🇮🇳 PESO / CMRI / CCOE Certified – For use in Zone 1 & Zone 2 Hazardous Areas
- ⚙️ IS 13947 / IEC 60947 – Switchgear & Controlgear Standards
- 🔰 IEC 61439 / IS 8623 – Low-Voltage Switchgear Assemblies
- 💡 ISO 9001 : 2015 – Certified Manufacturing Process
✅ Complies with Indian Explosive Act Rules and tested for gas group flammability and temperature rise criteria.
