JLLN015.T

JLLN015.T Application Field and Working Principle

JLLN015.T fuse is a time-lag, mid-range current-limiting device. It is designed to protect electronic circuits from over-current caused by internal or external faults. It is commonly used in industrial grade electrical control panels, motor control centers and energy generation systems like solar energy systems. The device is currently UL Listed, CE approved and meets the IEC 60269-2-2 standard.

JLLN015.T Characteristics

The JLLN015.T fuse has a rated voltage of 250 volts and a current rating of 15 amps. Its time-lag internal structure is designed to interrupt current up to 100 times its current rating. It also has a 2 millisecond interrupting time and an arc voltage of 235 volts. The surface mount model comes with a RoHS compliant package and a cyan color. The fuse is UL 94V-0 and UL 94V-2 flame rated, AC22A rated and has an operating temperature range of -55 to +125 C.

JLLN015.T Working Principle

The working principle of the JLLN015.T fuse is based on the original melting Theory. The fuse element, made up of a specially designed alloy steel body with an externally applied coating of Zinc Oxide, is designed to take advantage of physical properties characteristic of that material to melt the steel when the rated current is exceeded. The fusion of the metal molten droplets under high pressure leads to an arc. This process creates a plasma which absorbs most of the energy from the flow of the fault current. This results in a minimum heat applied to the fuse link which is then easily interrupted by the high arc voltage.

Applications

The application of JLLN015.T fuses is typically found in industrial grade motors and control systems, battery chargers, transformers, busbars and circuit breakers. The fuse is also used in electric generator sets, energy-saving lamp circuits, home appliances, solar energy systems, voltage regulators and power supplies. They are used to protect electronic circuits from large current and constant current, as well as other over-load conditions.

Advantages of JLLN015.T Fuses

The advantages of JLLN015.T fuses include their being time-lag fuses, having low power consumption, being RoHS compliant, and having UL 94V-0 and UL 94V-2 flame rated. They are also AC22A rated, have a 2 ms interrupting time, a shock resistant case and are easy to install and replace. The fuse also provides good arc-quenching performance, low contact resistance and long-term reliability.

Conclusion

Overall, the JLLN015.T fuse is a cost-effective solution for many applications. Its high current rating and low power consumption give it an advantage over other types of fuses. The fuse is easy to install and replace and provides reliable protection for a variety of electronic components making it a reliable choice for many applications.
