APPENDIX E
Current-Limiting Fuses for Use in
S&C PMH Pad-Mounted Gear
Types Accommodated and Adapters Required
S&C Holders for current-limiting fuses are designed for
use in pad-mounted gear models that include mountings
for Fault Fiter Electronic Power Fuses. In PMH Pad-
Mounted Gear, these holders will accommodate the
single-barrel current-limiting fuses listed in the table
below when the fuses are equipped with ⁵⁄₈-inch diameter
mounting studs at both ends. Depending on the length and
diameter of the current-limiting fuse to be used, adapters
may be required in order to fit the fuse in the holder.
Adapters, when required, are furnished with the S&C
Holder and are signified by a suffix to the catalog number
of the holder. For instructions on installing current-limit-
ing fuses in S&C Holders, refer to S&C Instruction Sheet
660-500.
