5.5kV - 15.5kV CL-14 series
5kv and 15kV Clip-Lock Mounted Fuses
Amp-trap CL-14 E-rated 5kV and 15kV fuses have 3" diameter barrels and
mount in unique cam-locking clips, for superior connections as well as
easy installation and replacement. They are UL listed as “general purpose
current-limiting fuses” and are for use indoors (or outdoors in a
weatherproof enclosure). The unique time-current characteristic of Ferraz
Shawmut E-rated fuses allows them to be closely sized to transformer full
load rated current, as recommended by IEEE guidelines, without being
affected by normal magnetizing inrush current. CL-14 fuses are typically
sized at transformer rated current of 133%, thereby providing superior
overall protection.

Definitions
E-rating
E-rated fuses operate as follows:
100E or less - must melt in 300 seconds (5 mins.)
at 200 to 240% of E (ampere) rating.
Over 100E - must melt in 600 seconds (10 mins.)
at 220 to 264% of E (ampere) rating.
Example - A 100E fuse must melt in 300 seconds
with an applied current of 200 to 240 amperes.
General Purpose Current-
Limiting Fuse
A general purpose current-limiting power fuse is
one that is capable of interrupting all currents
from its rated interrupting rating down to the cur-
rent that causes melting of the fusible element in
one hour.
