Heat Strips Fuses

By 1 March 2016

In the event a limit switch should fail, there is a back-up protection called fusible links. Unlike the regular fuse you have worked with, the links are constructed somewhat differently. In Fig. 10-4 two of the typical fusible links are shown. When these fuses open, they must be replaced as an assembly. They only open if the heat or amperage exceeds the unit limits.
