Introduction to GLX-1-1/2 Fuse

GLX-1-1/2 fuses, also known as dual-element fuses, are specifically designed for ac systems and are characterized by their high interrupting capacity. The GLX series fuse is compliant with IEC 60269, CSA-223, and UL 248-14 standards. It has a rating of up to 16000 volts, and a normal current rating of up to 1350 amps.

Application Fields of GLX-1-1/2 Fuse

This reliable fuse is extensively used in the automobile, power system, and lighting industry. Industrial applications where the GLX-1-1/2 fuse can be used includes but is not limited to:1. Motors2. Generators3. Transformers4. Switchgear5. Air compressors6. Boilers7. Welders8. Arc-furnaces9. Elevators10. Battery charging systems

Working Principle of GLX-1-1/2 Fuse

In GLX-1-1/2 fuses, a pair of fuses are inserted in a sheath. The first element, commonly known as the ‘current-limiting element’, consists of silver strips with a resistance of approximately 0.95 ohm which is connected in series between the fuse points and the terminals. The radio element, commonly known as the \'delay element\', consists of a small piece of wire enclosed in a ceramic tube that is connected in parallel with the current-limiting element across the fuse points. The function of the current-limiting element is to limit the rate of current flow an interrupt large current within a short period of time. This helps to reduce both the magnitude and the duration of the inrush current. The role of the delay element is to hold back or delay the current flow by introducing a time lag between the occurrence of the fault current and the breaking of the fuse element. This gives enough time for the protection system to deenergize the equipment before the current-limiting element opens.

Advantages and Disadvantages of GLX-1-1/2 Fuse

GLX-1-1/2 fuses have several advantages compared to other fuses. The advantages include the ability to withstand high overcurrents and heavy arcing without degradation, the ability to dissipate heat quickly to prevent damage to the surrounding environment, and the ability to be used in multiple applications due to their wide current ratings. However, GLX-1-1/2 fuses also have several disadvantages, such as being expensive and bulky, as well as being prone to damage due to mishandling. Therefore, it is important to take all necessary precautions when handling this type of fuse.

Conclusion

GLX-1-1/2 fuses are reliable and efficient components that are widely used in many industrial applications. They are capable of withstanding high current overloads and heavy arcing, and dissipate heat quickly to prevent damage. Though these devices are expensive and bulky, proper handling of them will ensure that they last for a long time.
