Fuses are important components in various electrical systems and are used to cut off current or power. In this article, we will discuss the application field and working principle of the BK1/GMA-750-R Fuse.

The BK1/GMA-750-R Fuse is a type of anti-surge fuses, and it is widely applied to industrial systems, electrical circuits of large power, and the controller modules of power distribution system, etc. It has anti-surge features and is able to withstand high voltage fluctuation. The rated current of the BK1/GMA-750-R Fuse is up to 750A, making it very effective and high-performance.

What makes the BK1/GMA-750-R Fuse exceptional is its working principle. The fuse consists of two metal parts - a metal ribbon and a metal case. The metal ribbon has a very specific temperature coefficient that is designed to melt very quickly with a sudden current surge. When a sudden current surge or short circuit occurs, the metal ribbon trips and cuts off the power, and the metal case becomes a thermal switch. This switch is designed to keep the power off until the short circuit or current surge has been rectified, preventing any further damage to the system.

Furthermore, the BK1/GMA-750-R Fuse also has over-heating protection and short-circuit protection features. This further increases safety for the system. The short circuit protection is designed to detect and automatically disconnect the power supply when a short circuit or current surge occurs. On the other hand, the over-heating protection is designed to detect and disconnect the power supply when the fuse temperature exceeds a certain threshold.

In conclusion, the BK1/GMA-750-R Fuse is an excellent and reliable anti-surge fuse for industrial systems, electrical circuits of large power, and the controller modules of power distribution system. It can effectively protect these systems from sudden current surges and short circuits, thus greatly improving safety and efficiency. Its working principle is simple and effective, making it very effective at preventing damages due to overvoltage.
