An electrical fuse is a current interrupting device which protects an electrical circuit in which it is installed by creating an open circuit condition in response to excessive current.

When the element in a fuse receives too much heat it will melt and interrupt the current. Fuses are usually used as a conduit between an electrical power source and an electrical component or a combination of components arranged in an electrical circuit. A fusible link is connected between the fuse terminals. This means that when an electrical current passing through the fuse goes beyond what the device is able to handle, the fusible link will melt and the circuit opens thus preventing electrical component damage.

Fuses are typically made for single time use. In other words, once it shuts a device down it must be replaced. You can get over-current protection from a variety of sources such as circuit breakers, switches, and relays. Each type of equipment has variations in ratings, service requirements and costs. Fuses are typically the most economical means for providing automatic high-voltage current protection against a single over-current failure.  Contact Electrical Supplies Unlimited for your electrical fuse supply needs.
