Sidewall Cover Mounted Fuse Holder – Medium Voltage Protection for Pad-Mounted Transformers

Our Sidewall Cover Mounted Fuse Holder is a robust and reliable fuse mounting solution designed specifically for pad-mounted distribution transformers. Installed on the transformer’s sidewall or top-mounted cover, this unit provides a secure and accessible location for housing bayonet-style or expulsion fuses, offering critical overcurrent protection in medium-voltage applications.

Engineered for 15kV–25kV class systems, this fuse holder features a fully shielded, submersible, and dead-front design, ensuring operational safety, even in harsh outdoor or underground environments. Constructed with high-durability materials such as peroxide-cured EPDM rubber and corrosion-resistant metals, it is compliant with industry standards and compatible with IEEE 386 separable connectors.

Key Features:

• Voltage Rating: 15kV / 25kV class
• Current Rating: Up to 200A (with appropriate fuse)
• Design: Cover- or sidewall-mounted installation for easy access
• Compatibility: Accommodates bayonet or expulsion fuses
• Safety: Fully shielded, dead-front, and submersible
• Material: High-quality EPDM insulation and stainless/brass hardware
• Standard Compliance: IEEE 386 and ANSI C37 standards

Applications:

• Pad-mounted distribution transformers
• Underground residential distribution systems (URD)
• Renewable energy substations (wind & solar)
• Medium voltage switchgear and protection cabinets

Advantages:

• Easy fuse replacement from outside the transformer tank
• Enhances safety and system protection against overcurrent
• Long service life in outdoor and subsurface environments
• Integrates seamlessly with loadbreak elbows and bushing wells

Our sidewall-mounted fuse holder offers utility-grade reliability and protection, ensuring safe, efficient, and convenient fuse management in medium-voltage transformer systems.
