Product Description

The Polymer Drop-Out Fuse Cutout (DOFC) is a medium-voltage protective device designed to safeguard overhead distribution systems and pole-mounted transformers from overloads and short-circuit faults. It combines the functions of a fuse and an isolating switch, automatically disconnecting faulty circuits by allowing the fuse carrier to drop open when the fuse link operates.

Manufactured with high-quality silicone polymer insulation and corrosion-resistant metal fittings, the fuse cutout offers excellent weather resistance, mechanical strength, and reliable performance in harsh outdoor environments. It is widely used by utility companies, industrial power distribution systems, substations, and renewable energy installations.

The drop-out fuse is suitable for protecting transformers, capacitor banks, overhead distribution feeders, and other medium-voltage electrical equipment.
