Metal Oxide Arrester (MOA)

The Metal Oxide Arrester (MOA) represents the most advanced solution for over-voltage protection. By utilizing a Zinc oxide barrier, this device significantly improves flow capacity and performance compared to traditional silicon carbide arresters.

Key Advantages

✅ Advanced Core Components: Utilizes high-performance Zinc oxide barriers.
✅ Superior Protection: Effectively limits over-voltage violations on transmission and distribution equipment.
✅ Intelligent Response: Operates at microamp levels during nominal voltage and handles thousands of amps during lightning strikes.
