CS-3 Series and 9F60/9F62 Series
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

Definitions:
General Purpose Current-Limiting Fuses
(Per IEEE Std C37.40-2003):
A general purpose current-limiting fuse is one that is capable of interrupting all
currents from its rated interrupting current down to the current that causes melting
of the fusible element(s) in one hour or more.
E-Rating:
E-Rated fuses are general purpose fuses that operate as follow (Per ANSI
C37.46-2000):
•
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.
