GLD-2

GLD-2 is an electrical, specialty fuse, typically employed in the protection of dc circuits. GLD-2 fuses offer superior performance in environments where fast tripping is required, including over current faults, short circuit faults, and ground faults. The fuse is designed to be used with an external fuse holder that offers short circuit protection and reduces voltage drop.

The construction of the GLD-2 fuse is unique because it has several layers of protection. The first layer consists of two elements in parallel, an upper element and a lower element. The upper element acts as a protection against overcurrent faults and the lower element acts as protection against short circuit. The two elements, when combined with the external fuse holder, provide three levels of protection. The first layer offers protection against over current, the second layer offers protection against short circuit, and the third layer offers protection against ground fault.

The GLD-2 fuse also has a special feature. It has a thermal reset feature that allows it to be reset in the event of an overload. This feature ensures that the fuse will not become permanently damaged if there is an overload. It is important that the fuse be reset in order to ensure that the circuit is protected from future faults. The thermal reset feature can be used in both ac and dc circuits.

The working principle of the GLD-2 fuse is quite simple. When an overcurrent condition or short circuit occurs, the heat generated by the current causes the fuse elements to expand and the fuse to open. This causes an interruption in the current flow and the circuit is protected from further damage.

The GLD-2 fuse is an ideal option for applications that require fast tripping and reliable protection from over current, short circuits, and ground faults. It is also suitable for use in both ac and dc circuits. Its unique design allows for two levels of protection, thermal resetting operation, and the ability to be reset. It is an excellent choice for applications where reliable protection and fast tripping are required.
