Semiconductor Fuse Blocks
Modular-designed Semiconductor fuse blocks are designed to
accommodate a wide range of Semiconductor fuses, with a
maximum diameter of 3". This modular design greatly
reduces inventory requirements. They are sold in pairs and
are constructed of molded phenolic, with plated steel studs.
