Drop-out fuse

The 10kV-15kV Fusibles with Load Break-Porcelain are engineered for reliable overcurrent and short-circuit protection in overhead distribution networks. Designed for safe load breaking under live operating conditions, this 10kV-15kV Fusible with Load Break-Porcelain ensures stable protection for transformers, reclosers, capacitor banks, and branch feeder circuits. With high-strength porcelain insulation and hot-dip galvanized steel hardware, this load break fuse delivers long-term electrical insulation, high mechanical endurance, and excellent resistance to UV, humidity, and corrosive outdoor environments. The visible break indication provides immediate confirmation of circuit isolation, improving operator safety and outage management efficiency.

Product Advantages:

• High mechanical and electrical endurance for distribution systems

• Porcelain insulation provides strong dielectric and environmental resistance

• Supports hot-stick load breaking for safe live-line operation

• Weatherproof structure suitable for harsh climates

• Fast and visible fuse dropout indication
