Fuse Applications

Fuse technology is highly versatile and can be used in the following key applications:

Fuses are the most cost effective, readily available and space efficient option for circuit protection particulary when compared with expensive, large circuit breakers. In the majority of applications, fuses provide faster and better current limitation than the alternative protection method.

Medium Voltage:

  • Utility power distribution
  • Overhead line protection
  • Underground cable protection
  • Substations
  • Heavy industry

Low Voltage:

  • Power distribution
  • Utility networks
  • Commercial buildings
  • Industrial sites
  • Machine protection
  • Automation

High Speed:

  • Power conversion protection
  • Railways
  • Electrical cars
  • Photovoltaic infrastructure
  • Industrial and commercial applications

Solar Fuses / PV

PV fuses are used to protect components within a solar PV array. This can range from individual panel protection to string or complete array protection. PV fuses are specifically designed for such applications and are rated up to 1500VDC making them the only choice to protect your investment. Other forms of protection are either not …
