Yes, it is highly effective for electrical panels when used in the right application. Electrical panel fires usually start from short circuits, loose connections, or overheating components inside a closed enclosure, where manual detection is delayed. An Automatic Fire Detection Tube Suppression System is designed specifically for such conditions. The heat-sensitive tube is installed inside the panel and continuously monitors critical points. When a fire or abnormal heat occurs, the tube ruptures at the source and releases a clean extinguishing agent, stopping the fire before it spreads outside the panel. Since the system works without power or human intervention, it remains reliable even during electrical failure. For enclosed panels, it is one of the most practical fire protection solutions available.
