When selecting a protective device for a new installation, be it a fuse, circuit breaker, or protective relay, it's good practice to become familiar with one or more of the many manufacturer's guides. These not only give specific product information, they provide in-depth information on the engineering discipline known as circuit coordination. When installing a protective device, you are not only protecting the specific device and circuit, you're also protecting the upstream devices and loads. Several companies make software packages that take the pain out of doing short-circuit analysis, coordination, application, and specification - all important aspects of providing proper protection to any power distribution system.
Selecting replacement fuses is easy now with Windows-based cross reference software and computerized catalogs. No longer do you have to flip through pages of charts. With a few keystrokes, the information you need will appear on screen. You can order periodic updates and stay on top of the latest developments in the fuse industry.
