What are Fuses?

Fuses are safety devices that are designed to sacrifice themselves in order to protect equipment from over current. That is to say, that fuses are an intentional weak link in an electrical circuit. A weak link that is designed to break if a power surge occurs before that surge can reach expensive or sensitive equipment. They are similar in a sense to breakers except that a breaker can be reused multiple times whereas a fuse can only be used once. For the most part, fuses are essential in electrical circuits for the protection function they provide and the safety that they offer.

What are fuse blocks?

A fuse block is a device that distributes power to multiple circuits and houses a fuse for each of those circuits. In this way, a fuse block is a gatekeeper where a surge cannot pass. Instead of having fuses all over the place for each circuit, a fuse block allows you to consolidate those fuses into one centralized location. Fuse blocks are available in a variety of sizes in styles to meet the needs of the different types of fuses we offer. One question we frequently hear is about the different types of fuses that we offer.
