Fuse is a primary safety device that is a thin wire enclosed in a casing or glass that connects two metal parts. This wire melts when more current flows in the circuit. Electrical Protection Device Types Of Circuit Protection Devices Solutions for problems in chapter 3CM. . One of the first forms of circuit protection is the fuse. They are also much easier to use with onoff switching for circuit isolation and are much safer as the conductor is. The electric protection system must be able to detect all faults on the protected line. A fuse is probably the simplest electrical device but its function is critical in protecting electrical circuits from damage. Buy Today Get Your Order Fast. You will find a microcontroller. These devices are sensitive to the type of. They are widely used in interfacing outdated devices and SD cards SIM cards etc. A fuse is the most common protection device. A lev
