FUSE CUTOUTS

Reliable Primary Protection for Overhead Distribution Networks

At Integrated Power & Engineering, we supply high-performance Fuse Cutouts designed to provide dependable primary overcurrent protection in medium-voltage overhead distribution systems. These fuse cutouts play a critical role in protecting distribution transformers, overhead lines, and network equipment from overloads, short circuits, and fault conditions.

Built for safety, durability, and easy field operation, our fuse cutouts are trusted by utilities and project developers for consistent performance in both urban and rural environments.

What Our Fuse Cutouts Do

A fuse cutout is often the first line of defense in an overhead distribution network. When a fault occurs, it quickly isolates the affected section—preventing damage from spreading further and keeping the rest of the system energized.

Our fuse cutouts are designed to:

  • Disconnect faulted equipment safely and visibly
  • Limit damage to transformers and conductors
  • Reduce outage time and maintenance effort
  • Improve overall network reliability

Key Features & Practical Benefits

Reliable Fault Isolation

Automatically disconnects faulted sections to protect transformers and overhead lines—helping utilities minimize equipment damage and service disruption.

Strong Insulation for Outdoor Use

Available in porcelain or polymer housings, both designed to withstand rain, heat, UV exposure, and pollution common in outdoor installations.

Easy Field Maintenance

Fuse links can be replaced safely on-site without dismantling the cutout, allowing quick restoration of service and reduced manpower effort.

Corrosion-Resistant Construction

All metallic components are hot-dip galvanized or stainless steel, ensuring long service life even in coastal, industrial, or high-humidity areas.

Effective Current Limiting

Helps restrict fault current and ensures that only the affected section of the line is isolated—keeping the rest of the network operational.

Compact & Installer-Friendly Design

Lightweight and space-efficient, making installation straightforward on pole-top transformers and overhead lines.

Typical Applications

  • Pole-mounted distribution transformer protection
  • Rural and urban overhead distribution lines
  • Renewable energy grid connections (solar and wind)
  • Industrial estates and utility distribution networks
  • Substation outgoing feeder circuits
