Superior Protection for Distribution Lines

This cutout provides essential safeguarding for single-phase power distribution lines, effectively isolating faulty segments in outdoor environments. Its high dielectric strength (28 kV) and arc-quenching capability ensure safe interruption of overcurrents, minimizing equipment damage and service disruption. Featuring a durable glazed porcelain body and corrosion-resistant metal contacts, it operates reliably in harsh weather and humidity up to 95% RH, delivering long-lasting, maintenance-friendly protection.


User-Friendly Installation and Maintenance

Designed for seamless integration on utility poles, the cutout features a rectangular base and cylindrical housings, complete with bracket and clamp mounting hardware. It accommodates standard 400A fuse links via bolt/clamp terminals and includes copper end connectors for secure connections. Maintenance is simplified thanks to the tool-free fuse link replacement process, reducing downtime and enhancing operational efficiency for utility companies.

FAQs of 400A Pole Mounted Single Pole Cutouts:


Q: How is the 400A pole mounted single pole cutout installed on utility poles?

A: Installation is carried out vertically using the provided galvanized brackets and bolts, ensuring secure attachment to a utility pole. The standard size and mounting accessories guarantee compatibility with most pole types, while copper end connectors facilitate reliable terminal connections.

Q: What are the main benefits of using this fuse cutout for distribution line protection?

A: The fuse cutout offers high arc-quenching capability, quick fault isolation, tool-free maintenance, and weatherproof construction. These features ensure increased safety, prolonged equipment life, and minimal power interruption in outdoor distribution networks.

Q: When should the fuse link in the cutout be replaced, and how is it done?

A: The fuse link should be replaced after it has operated in response to a fault or overload condition. The process is tool-free and can be completed quickly by carefully opening the cutout and swapping in a new standard 400A fuse link, enabling fast restoration of service.

Q: Where can this cutout be used, and what environments is it suitable for?

A: Designed for outdoor power distribution lines, this cutout is ideal for installation on utility poles in various climates. It is engineered to perform optimally in challenging environments, withstanding humidity up to 95% RH and temperature fluctuations from -10C to +60C.

Q: What materials are used in the construction, and how do they enhance durability?

A: The body uses high-grade porcelain for excellent insulation and weather resistance, while contacts are made of tin-plated copper/brass, providing superior conductivity and corrosion resistance. These materials ensure a long service life exceeding 10 years, even in demanding outdoor conditions.

Q: How does the cutout respond to power surges or faults in the distribution line?

A: Upon detecting a power surge or short circuit exceeding its 400A rating, the fusible element melts, instantly isolating the affected section. This quick action prevents equipment damage and enhances the safety and reliability of the distribution network.
