The fuse is an electric device that is used to provide the safety to your electronic equipments and protect an electric circuit against an excessive current. It is connected in series with the circuit it is to protect because of its electrical resistance; the alloy strip in the fuse is heated by an electric current. The fuses are designed using the highest quality materials and manufacturing methods. If the current exceeds the safe value for which the fuse was designed, the strip melts, opening the circuit and stopping the current. Fuses are over current protective devices that contain a calibrated current-carrying element which melts and opens under specified over current conditions. A fuse consists essentially of a strip of low-melting alloy enclosed in a suitable housing.
Fuses can be used for a variety of over current and overload applications. The choice of one type or the other depends on the ruggedness of the equipment to be protected and whether large pulses of current often occur in the circuit; a slow-blow fuse is usually used to protect motors, and a fast-blow fuse to protect electronic equipment. The fuse protection against overload and short-circuit in electric lines and also available for protection of semi-conductor parts and equipment against short-circuit. Some fuses are designed to carry a small overload for a short time without opening the circuit and others are designed to open very rapidly if the rated current is exceeded. These can save the energy at maximum, and have lower operating cost and quick economic return.
