Product Description

This outdoor dropout fuse, equipped with an arc-extinguishing hood, is manufactured in strict accordance with IEC standards and undergoes comprehensive factory testing. With a rated current range of 10 A to 200 A, it is designed to protect overhead distribution lines and pole-mounted transformers from overload and short-circuit damage.

This outdoor dropout fuse external arc-extinguishing hood effectively contains the arc generated during fault interruption, preventing it from spreading outward. Upon overload or short-circuit, the fuse element melts rapidly; the fuse tube works in tandem with the arc-extinguishing chamber to quickly quench the arc. Subsequently, the fuse tube automatically drops to the open position, creating a clearly visible disconnection gap that facilitates fault inspection and ensures maintenance personnel safety. By effectively limiting arc spread, the hood minimizes the risk of phase-to-phase short circuits in windy conditions, offering a significant advantage in such environments - hence its designation as a "wind-resistant" dropout fuse.

The product's insulator features ample creepage distance and excellent resistance to pollution, flashover, and weathering; the main body is constructed from high-strength glazed porcelain, making it suitable for long-term outdoor operation.

This outdoor dropout fuse All metal components undergo hot-dip galvanization for corrosion protection, while copper contacts ensure high conductivity and low contact resistance.

Detailed test reports meeting international tender and on-site acceptance requirements are provided with the shipment, along with ISO and CE certifications.
