AutomationDirect is pleased to carry the most popular Class CC, Class J, Class RK and Class M general purpose fuses for industrial control applications.

The Class CC current limiting fuses, frequently used in applications for small motor branch circuit protection, are available in both time-delay and fast-acting models. Because of their superior current limiting performance, these Class CC products are sometimes regarded as an upgrade to the Class M general purpose fuses. In addition, the CC line is recognized for NEC branch circuit protection and Type 2 coordinated applications for IEC or NEMA starters/contactors.

Where adherence to extensive current limiting codes is not required, the Class M general purpose midget fuses and small dimension fuses are a great low-cost solution for both time-delay and fast-acting protection.

Class J ... JDL Series - Time-delay fuse 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 $78. (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 $21.25 (ECNR15 - per package of 10).

We have not forgotten the accessories you need: several fuse holder and fuse blocks are available in a variety of 1, 2, and 3 pole form factors.

----------------------------------------------------------- 10 Great Reasons to Use a Fuse

Why use a fuse? Fuses offer a safe and economical solution for overcurrent protection of both conductors and components. Fuses can help make your control systems meet the newest UL and NEC codes.

1. Safety - Overcurrent protective devices that have tripped are often reset without first investigating the cause of the fault. Electromechanical devices may not have the reserve capacity to open safely when a second or third fault occurs. When a fuse opens it is replaced with a new fuse, so the protection level is not degraded by previous faults.

2. Cost effective - Fuses typically are the most cost effective means of providing overcurrent protection. This is especially true where high fault currents exist or where small components such as Control Transformers (CPTs) or DC power supplies need protection.

3. Reliability - Fuses have no moving parts to wear out or become contaminated by dust or oil.

4. North American standards - Tri-National Standards specify fuse performance and maximum allowable fuse let-thru values.

5. High interrupting rating - With most low voltage current limiting fuses (less than or equal to 600 volts) having a 200,000 A interrupting rating, you are not paying a high premium for a high interrupting capacity.

6. Component protection - The high current limiting action of a fuse minimize or eliminates component damage.

7. Extended protection - Devices with low interrupting ratings are often rendered obsolete by service upgrades or increases in available fault current. New NEC and UL standards are causing the need for potentially expensive system upgrades to non-fused systems.

8. Selectivity - Fuses can be easily coordinated to provide selectivity under both overload and short circuit conditions.

9. Minimal maintenance - Fuses do not require periodic recalibration as do some electromechanical overcurrent protective devices.

10. Long life - As a fuse ages, the speed of response will not slow down or change. A fuse's ability to provide protection will not be adversely affected by the passing of time.

...AND THE BEST REASON OF ALL - OUR PRICE!

AutomationDirect has secured incredible pricing for all our fuses, fuse holders and fuse blocks, and has passed those savings on to you. Many items are priced well below industry list prices, making fuse protection a beneficial and affordable option for almost every electrical device.
