Fuses, Fuse Holders and Fuse Blocks Check out our competitive prices New! ... Class J high-speed drive fuses! 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. Cooper Industries is a $4.1B corporation with seven electrical products divisions, including two fuse brands, along with fuse holders and fuse blocks. 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/Mersen, Siemens, and many more. See the manufacturer cross reference list in the Technical Info section for this 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. Electrical and electronic fuses can be used to protect transformers, motors, DC power supplies, lighting circuits, contactors, relays and other industrial and commercial electrical equipment and conductors. Circuit Protection - Fuses Catalog Section (Section 31) The Edison family of industrial fuses is divided into two classes: Current Limiting: Class CC, Class J, High Speed Class J, Class RK, Class T General Purpose: Class M Midget and Small Dimension The fuse selection guides below are general summaries of the specifications included for each industrial fuse type. These fuse selection guides do not include the many variables that can exist for specific situations such as local codes, unusual temperature, or other operating conditions. When selecting industrial Edison fuses, be sure to comply with any applicable PUBLIC SAFETY standards that apply to over-current Protection Devices (OPD).

Current Limiting Fuses

AutomationDirect carries the most popular Class CC, J, RK and T current limiting fuses for industrial control applications.
These current limiting fuses, frequently used in applications for motor branch circuit protection, are available in both time-delay (slow blow), fast-acting and high speed extremely fast acting models.
In addition, the CC line is recognized for NEC branch circuit protection and Type 2 coordinated applications for IEC or NEMA starters/contactors.

Class J

• JDL Series - Slow blow fuse (time delay) with space-saving dimensions and high performance.
  Recommended for Type 2 (no damage) protection of IEC style motor starters and contactors.
  
  
• Packages of Class J Current Limiting Fuses start at $114.00 (JDL1 - per package of 10).

Class RK

• ECNR/ECSR Series - Time-delay, dual element construction with superior overload and cycling capabilities.
  Recommended for AC power distribution system mains, feeders and branch circuits. RK5 current limiting.
• LENRK/LESRK Series - Time-delay fuses having up to 40% more current limiting than ECNR/ECSR series. RK1 current limiting.
• Packages of Class RK Current Limiting Fuses start at $33.00 (ECNR15 - per package of 10).

Class CC

• HCLR Series - Fast-acting, compact fuse design rated for 600 VAC. Applications include lighting and resistive heating loads.
• HCTR Series - Time-delay design allows closer sizing for inductive loads such as control transformers and solenoids.
• EDCC Series - Time-delay design for motor branch circuit protection. Use for protection of small horsepower motor circuits.
• Packages of Class CC Current Limiting Fuses start at $60.00 (HCLR10 - per package of 10).

Class T

• TJN and TJS Class T fuses are extremely fast-acting industrial fuses in a compact, space-saving size.
• TJN Series - 300 VAC, 1-200 Amp, 225-600 Amp
• TJS Series - 600 VAC, 1-200 Amp, 225-600 Amp
• TJN and TJS Class T fuses are ideal as the main fuse protection for panel boards, load centers, meter stacks, and AC drives.
• Packages of Class CC Current Limiting Fuses start at $6.50 (TJN1-1 - per package of 1).

General Purpose Fuses

AutomationDirect carries two classes of general purpose fuses: midget class and small dimension electronic.
A Class M general purpose midget fuse is a great low-cost solution when adherence to extensive current limiting codes is not required.
Small dimension, slow-blow and fast-acting electronic fuses come in two standard sizes, 1/4 in. x 1-1/4 in. and 5mm x 20mm, and have nickel-plated brass end caps.

Class M - Midget

• MCL/MOL Series - Fast-acting, compact midget fuse design rated for 250 and 600 VAC. Used in control circuits and for electronic equipment protection.
• MEQ/MEN Series - Time-delay design allows harmless inductive surges to pass without needless fuse opening.
  Used for supplemental protection of transformers, solenoids and other high-inrush circuits.
• Packages of Midget class fuses start at $10.75 (MOL10 - per package of 10).
