BK/GMF-1/2

BK/GMF-1/2 are speciality fuses primarily used in electrical engineering. They are cylindrical, slow-acting fuses designed to offer protection against short-circuits over a wide range of electrical currents and high fault currents. In general, the BK/GMF-1/2 type of fuses have a wide variety of uses in different industries and applications.

The most frequent uses of BK/GMF-1/2 fuses are in industrial and commercial environments. Due to their relatively large cylindrical size, they are the preferred choice for applications where higher safety and lower costs are desired. Common applications of these fuses include motor branch circuit protection, receptacle protection, and generator branch circuit protection. Additionally, they can be used in power distribution systems, control equipment, and motor control centers.

In terms of their working principle, BK/GMF-1/2 fuses are very simple. the fuse itself is filled with a gas or liquid, which flows into the fuse link when a predetermined current level is reached. This flow then acts as a thermal breaker, causing the link to expand and eventually open, shutting off the circuit in the process. The link then reset itself to the regular size, which allows the circuit to be restarted safely.

The main advantage of using BK/GMF-1/2 fuses are that they are able to react quickly to the excess current and effectively break the circuit in a short time. This prevents the buildup of extreme levels of heat, and therefore reduced the risk of fire in the system. Moreover, because they are filled with a gas or liquid, they can also be reset without having to be replaced, saving the user time and money.

Furthermore, BK/GMF-1/2 fuses are also highly reliable in terms of their performance and are able to remain operational for many years with minimal maintenance. This ensures that the user always has the protection they need in case of a short circuit. Additionally, these fuses are UL approved, meaning they meet the most stringent safety regulations and can be used with confidence in any system.

In conclusion, BK/GMF-1/2 fuses provide an extremely cost effective and reliable type of circuit protection. Their ability to quickly react to high currents, reset without the need for replacement, and meet the most stringent safety regulations makes them a popular choice for a wide variety of applications.
