General Purpose
Bullet™ Class RK5
Dual-Element Time-Delay Fuses
ECNR/ECSR Dual Element Fuses
These fuses are recommended for AC power distribution
system mains, feeders and branch circuits having inductive
loads (motors, transformers) or non-inductive loads
(lighting, heating) where the available short-circuit current
does not exceed 200,000 RMS symmetrical amps. These
“dual-element, time-delay” fuses have minimum industry
standard time-delay of 10 seconds at 5 times the fuse rating
(8 sec. minimum for 250V, 30A and less). The time-delay
characteristics of these fuses typically allows them to be
sized closer to the running ampacity of inductive loads to
reduce cost and provide improved overcurrent
protection. These fuses will override normal equipment
current surges to reduce unnecessary fuse openings. They
are the most popular fuses used in the industry and the
most economical for most applications, especially motors
and transformers. They have moderate current limitation.
Class R fuses will fit Class H, K and R fuse clips. Class R fuse clips will only accept Class R fuses. Fuses rated 600Vac
or less may be applied at any lower voltage. Contact Edison Custom Satisfaction for special products or applications.

Circuit Protection
True Dual-Element Construction
Insulated end-caps to prevent
accidental contact with live parts.
UL/CSA Fuses
General Purpose
LENRK/LESRK Dual-Element Fuses
The application recommended for these fuses is exactly the
same as for the Edison ECNR/ECSR fuses except for the
advantages of greater current limitation. The Edison
LENRK/LESRK fuses have up to 40% more current
limitation and up to 350% more Amps-Squared-Second (I2t)
limitation under fault conditions than Edison ECNR/ECSR
fuses to reduce potential for damage. In addition,
LENRK/LESRK fuses allow better selectivity for electrical
power system designers and better short-circuit protection
for breakers having inadequate interrupting ratings.
ECNR/ECSR and LENRK/LESRK fuse lines are physically
interchangeable (and electrically interchangeable per UL
equipment listing conditions) and are recommended as a
practical, economical way to upgrade systems for many
situations.

NCLR CLASS RK1 FAST-ACTING FUSES
SCLR CLASS RK 1 FAST-ACTING FUSES
Application:
Edison NCLR/SCLR Class RK1 fast-acting fuses are
recommended for general power distribution system use for
main, feeder and branch circuits having a high percentage
of non-inductive loads such as heating and lighting.
NCLR/SCLR fuses are suitable for circuit breaker
protection.* When NCLR/SCLR fast-acting fuses are used
for inductive loads, the fuses usually require oversizing to
override normal transient current surges of motors and
transformers. Oversizing fuses usually increases fuse and
equipment cost and reduces overcurrent protection. (For
inductive loads, LENRK/LESRK fuses are recommended).
NCLR/SCLR Class RK1 fast-acting fuses are physically
interchangeable with other Class R fuses. They will replace
Class K or Class H fuses in standard fuse clips.
*When used as recommended by a specific circuit breaker manufacturer for a
specific application.

LCL: 300 - 4000 Amps
LCU: 601 - 6000 Amps
Interrupting Rating:
200,000 RMS Symmetrical Amps
* Not UL Listed (See note below).
Current Limiting:
Class L Fuse
LCL: Time-delay of 5 seconds minimum at 500% rated current
allows closer sizing.
Agency Approvals:
UL Listed, Class L, Guide JDDZ, File E162363
CSA Certified HRC-L per C22.2, No. 248.10
NOTE: LCL 300 - 500 amp fuses are physically the same as 800
amp size; Use in 800 amp switch where load current is not
fully utilized and a smaller fuse amp size is desired. Also
useful in new installations to allow for future upgrades in
service.
Benefits:
• “O-ring” construction insures maximum current limiting
ability.
• Silver plated micro-peened terminals.
• High strength melamine fuse tubes.
Recommended Sizing:
LCL: 150% or more of motor full load current.
Recommended Upgrade:
None Available.
Applications:
• LCL: Recommended for AC power distribution system
mains and large feeders.
• LCU: Recommended for non-inductive heating and
lighting loads. Also suitable for protection of low

Circuit Protection
Class L Fuses Specification:
Install Class L Fuses in switches rated 601-6000 amps
and in AMP RATINGS and “time-delay” or “fastacting” types as shown on the plans. Installed and spare
“time-delay” fuses shall be Catalog Number LCL and “fastacting” fuses shall have silver links and be Catalog Number
LCU. Fuses shall be Edison fuses or equivalent submitted
to the design engineer for approval 10 days prior to the
project bid date.
Mounting of “Bolt-On” Fuses shall be made by installing
stainless steel bolts of correct number, diameter and
length*, stainless steel spring washers on each side of the
bolt and stainless steel nuts. The nuts shall be tightened to
the torque recommended by ASTM Standards for the bolt
size used.
UL/CSA Fuses
General Purpose
General Application:
Edison Class L fuses, Catalog Numbers LCL time-delay or
LCU fast acting are recommended for high capacity main,
feeder or branch circuits in power distribution systems and
for special applications such as system upgrading, install
ahead of network protectors, etc. The choice of LCL or LCU
depends on the extent of mixed inductive and non-inductive
loads diversity. Apply LCL fuses for protection of large
individual motor circuits. Size LCL fuses at 150% or more of
the motor nameplate current rating by checking starting
characteristics against minimum melt Time-Current Curve.

Edison JDL Class J fuses are among the most current
limiting time-delay fuses available. Their small physical size
and high performance characteristics makes Class J fuses
ideal for any space-limited application.
Benefits:
• Space saving dimensions vs. Class R.
• Dual-Element construction provides superior time-delay
to pass harmless motor or transformer surges.
• High performance with fatigue - free cycling capabilities.
• Extremely current limiting.

Edison Class T fuses are extremely fast-acting fuses in a
compact, space saving size. These fuses are ideal as the
main fuse protection for panelboards, load centers and
meter stacks.
Benefits:
• No intentional time-delay; opens quickly on overload.
• Extremely current-limiting silver link construction; provides
superior short-circuit component protection.
Applications:
• Recommended for protection of non-inductive loads, such
as lighting and resistance heating circuits.
• Use to protect lower interrupting rating circuit breakers
when series rated with Class T fuses.
• For motor protection, size at 300% FLA which provides
short circuit protection only.
