Product Details

Product description

In normal operation, the fuse link is tightened to form tho closed position. In the fault current situation, the fuse link melts and an electrical arc is formed. The arc-extinguishing tube is as occurs. This causes high pressure inside the tube and causes the tube to separate from the contacts. The strength of the contact is relaxed once the fuse elements melt. The cutouts now in the open position, the operator needs to switch the current off. Then with an insulated operating bar, the moving contact can be pulled off. The main contact and auxiliary contact is connected.
