CYLINDER
with Bolt Tabs
for Semiconductor Protection
Bolt tab cylinder fuses are typically used
for protecting semiconductors like diodes,
SCR’s, etc. They are current limiting,
super fast blow fuses in the gR operating
class.
They are available in two diameters with
multiple fixing centers. The fuses have a
porcelain body, metal caps at both ends,
and bolt tabs.
