CYLINDER
Cylinder Fuses are typically used in
industrial applications to protect electrical
devices such as motors, drives, etc.
They are available in four sizes with a
current range from 1 to 125 Amps.
Cylinder Fuses have metal caps at both
ends, and a porcelain fuse body.
Please refer to pg 15 for ordering in-
formation for Cylinder Fuse Bases.
