① The single-barrel current-limiting fuses listed in this table are to be
purchased from the appropriate current-limiting fuse manufacturer.
② The maximum voltage and maximum ampere ratings listed in this
table apply when the corresponding current-limiting fuse is used.
Con sult the appropriate current-limiting fuse manufacturer for complete
fuse ratings.
③ S&C Holders for use in 14.4-kV models of PMH Pad-Mounted Gear
are rated 14.4 kV nominal, 17.0 kV maximum, and 200 amperes maxi-
mum. S&C Holders for use in 25-kV models of PMH Pad-Mounted Gear
are rated 25 kV nominal, 29 kV maximum, and 200 amperes maximum.
④ Includes adapters when required.
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 Table 7 when the fuses
are equipped with ⅝-inch (16-mm) 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 t the fuse in the holder. Adapters,
when required, are furnished with the S&C Holder and are
signied by a sufx 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.
