Transformer Protection
Amp-Trap® CS-3 Series and 9F60/9F62 Series
MEDIUM VOLTAGE FUSES
2.75KV, 5.5KV, 8.25KV, 15.5KV, 25.8KV AND 38KV
FERRULE MOUNTED FUSES
Mersen fuses for the protection of transformers and distribution lines
deliver overload and short circuit protection. These current-limiting
fuses will melt at current that can be as low as 1.7 times the fuse
current ratings up to its maximum interrupting rating. These fuses are
designed to withstand the transformer magnetizing inrush current.
They have 2 (size C), 3 (size D) and 4 (size E) inch diameter barrels
with ferrules and are mounted in spring reinforced clips.
FEATURES/BENEFITS:
• Amp-Trap CS-3 and 9F62 series are UL listed for compatibility
with UL listed equipment.
• Ferrule mounting for standard clips and interchangeability with
other brands of fuses.
• Current-limiting for superior equipment protection.
• Non-venting for silent operation.
• Metal embossed catalog number and manufacturing date for
lasting identification.
• Outdoor usage for the 9F62 and 9F60 type EJO.
• Blown-fuse indicator to give positive identification of open fuse:
• Amp-Trap: 2" Barrel 1 lb tripped force - 0.19 Inch
• Amp-Trap: 3" Barrel 2 lb tripped force - 0.50 Inch
• 9F60/9F62: 0.125 lb tripped force – 0.20 Inch
• Accessories - see Section FB
RATINGS
• See next page for listing
HIGHLIGHTS:
• E-Rated
• UL listed
• Outdoor use
APPLICATIONS:
• Protection for 2.4kV to
34.5kV transformers or
distribution systems.
APPROVALS:
• Some UL listed to standard

DEFINITIONS:
General Purpose Current-Limiting Fuses (Per IEEE
Std C37.41-2016):
A general purpose current-limiting fuse is one that
is capable of interrupting all currents, from its rated
maximum interrupting current down to a low value
equal to the current that causes melting of the
fuse elements in one hour or more, under specified
conditions.
E-Rating: E-Rated fuses perate as follows (Per
IEEE C37.42-2016):
• 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.
Power Distribution Fuses:
Defines fuses designed prior to the time where the
ANSI standards defined the term “General Purpose”
and do not meet all of the general purpose
definition. These fuses are capable of interrupting
all currents above 2.2 to 3 times the fuse’s rated
current up to its maximum interrupting rating.
