DOMESTIC AND INDUSTRIAL CYLINDRICAL
FUSE-LINKS
Ferraz Shawmut gF, gI-gG and aM fuse-links cover a
wide range of physical sizes and ampere ratings for
250, 400, 500, and 690 volts AC. gF fuse-links are for
domestic use. gI-gG and aM fuse-links are for industri-
al applications. Most ratings are available with an
optional indicator. All industrial fuse-links have the
option of a built-in striker. All cylindrical fuse-links
have ceramic bodies and silver-plated ferrules.
