Fuses, Fuse Holders and Fuse Blocks
New! ...Higher current ratings (from 200 amps to 600 amps) on current limiting fuses!
Get the protection you need at a price you’ll love!AutomationDirect has teamed up with Edison Fuse, a subsidiary of Cooper Industries, the worldwide leader in circuit protection, to offer the Edison line of fuses, including fuse holder and fuse block products.The Edison Fuse products are industry-standard fuses that are designed using the highest quality materials and manufacturing methods. All Edison fuses can be directly cross referenced and used as replacements for other name-brand fuses such as Littelfuse, Ferraz, Siemens, and many more. See the manufacturer cross reference list in the Technical Info section for the Circuit Protection/Fuses product category on our Web site, or in our free product catalog. Fuses are overcurrent protective devices that contain a calibrated current-carrying element which melts and opens under specified overcurrent conditions. Fuses can be used for a variety of overcurrent and overload applications. They can be used to protect transformers, motors, DC power supplies, lighting circuits, contactors, relays and other industrial and commercial electrical equipment and conductors.A Current-Limiting Fuse meets the following three conditions:
- Interrupts all available overcurrents within its interrupt rating.
- Within its current limiting range, limits the clearing time at rated voltage to an interval equal to, or less than, the first major or symmetrical current loop duration.
- Limits peak let-through current to a value less than the available peak current.
Industrial Fuses - Current Limiting Class J
EDISON JDL Class J fuses are among the most current limiting time-delay fuses available. Their small physical size and high performance characteristics make Class J fuses ideal for any space-limited application.
JDL Series - Current Limiting Class J FusesApplications
- Recommended for Type 2 (no damage) protection of IEC style motor starters and contactors.
- Use to protect lower interrupting rated circuit breakers.
- All general purpose circuits with inductive (high inrush) loads, including motor and motor branch circuits, and transformer circuits.
- Also suitable for lighting loads.
- Space saving dimensions compared to 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
Agency Approvals UL Listed, Class Class J, Guide JDDZ, File E162363CSA Certified HRCI-MISC per C22.2, No. 248.8
Industrial Fuses - Current Limiting Class RK5
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 amperes. 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.
ECNR Series - Dual Element Time-Delay Class RK5 FusesApplications
- Recommended for AC power distribution system mains, feeders, and branch circuits
- Protection of motors and motor branch circuits
- Protection of transformers and other inductive loads
- All general-purpose applications including lighting, heating and other non-inductive loads

Industrial Fuses - Current Limiting Class RK1 Fuses
LENRK/LESRK series fuses have up to 40% more current limitation and up to 350% more Amps-Squared-Second (I2t) limitation under fault conditions than ECNR/ECSR series fuses, reducing the potential for damage. They also offer a better selection for electrical power system designers and superior short circuit protection for breakers having inadequate interrupting ratings. ECNR/ECSR and LENRK/LESRK fuse lines are physically interchangeable (and electrically interchangeable per U.L. equipment listing conditions). We recommend them as a practical, economical way to upgrade systems in many situations.
