The 500 V~100 A fuse provides over-current protection to your electrical circuits. As a leading producer of electrical supplies, our state-of-the-art production lines guarantee the quality and functionality of each individual fuse product. The heat-sensitive metal wire inside of the fuse would melt as soon as the electrical circuit is being overloaded due to over-current. The thermal property of the metal wire allows the fuse to have both low electrical resistance as well as high heat sensitivity, so that it is best suited for industrial applications.
The working principle of the fuse is a simple relationship between I2R and time. The greater the current, the shorter the fusing or opening time. The power consumption of the fuse is proportional to the square of the current through the fuse. When the power consumption is too high, the fuse blows. This feature also applies to wire harnesses protected by fuses. If the amount of heat generated exceeds the heat of distribution, the temperature of the fuse will increase, when the temperature rises to the fuse fuse melting point fuse occurs when the fuse is to open the circuit to play a protective role
