What Are The Factors That Affect The Service Life Of The Fuse?

Fuse, installed in the circuit equipment, to ensure the safe operation of circuit components, the use of high resistivity, low melting point of silver copper alloy made, in the circuit work, the external working environment temperature, the internal pulse current and so on will affect the service life of the fuse, high temperature environment, reached the melting point of the metal, resulting in severe oxidation, Production of thermal stress fatigue phenomenon, will speed up the scrap of the fuse, so, the working environment temperature to ensure that the appropriate, working time should be reasonable, can not be too long.

Pulse Current, is an important interference factor, constantly circulating pulses, will produce a thermal cycle, resulting in melting wire diffusion, oxidation, thermal stress phenomenon, accelerate aging.

In addition, a number of other factors will also affect the performance of the fuse, connecting the length of the wire, cross-sectional area, contact resistance size, affecting the working performance of the fuse. When the fuse appears aging phenomenon, do not worry about safety issues, should find professional maintenance personnel to repair. Resolve failure issues in a timely manner.
