Introduction

BK/GMF-2-1/2 is a type of electrical specialty fuses. It is mainly used in fusion welding of electrical circuits. It protects the circuit from over current disturbances. It also reduces the risk of fire associated with short-circuiting.

Design and Construction

The BK/GMF-2-1/2 is made up of a metal shell, a cylindrical hollow body, and two internal contact terminals. It has a cylindrical shape, with a cylindrical cap and a bottom flange. The metal shell is painted yellow, with a center mark in black ink. The top and bottom flanges are designed to provide secure attachment to the baseplate.The internal contact terminals are made from copper, with a silver-plated gold finish. The contacts contain a thin layer of flux coating to provide protection against corrosion and electrical arcing. The contacts are connected to the fuse by a series of rivets.

Working Principle

The primary purpose of the BK/GMF-2-1/2 is to open a circuit in the event of an overload or a short circuit. This is done by melting the internal contacts of the fuse. When the indicates a current condition that exceeds the preset rating of the fuse, the internal contacts heat up and expand. This causes the contacts to separate and break the circuit. The fuse then remains open until it is reset or replaced.

Application Field

The BK/GMF-2-1/2 is primarily used in the welding process of electrical circuits. It is designed to protect against over current disturbances as well as reduce the risk of fire due to short circuiting. It is also used in other power supply devices such as power supplies, circuit protection devices, and power tools.It is also used in automotive applications, such as in the fuse box for the lights and other accessories. In this application, the BK/GMF-2-1/2 is used to limit the current to a safe level, so that the fuse does not blow in case of an overload.

Advantages

The BK/GMF-2-1/2 provides many advantages over traditional fuse designs. Its cylindrical shape allows it to be easily installed into the fuse box or other power supply devices. Its silver-plated gold contacts provide superior corrosion protection as well as electrical arc protection.The design of the fuse also allows it to be reset after it has opened. This makes it easier to reset and reinstall the fuse, saving time and money.

Conclusion

The BK/GMF-2-1/2 is a type of electrical specialty fuse. It is mainly used in the welding process of electrical circuits, to protect against damage due to over current disturbances. It has a cylindrical shape, with a silver-plated gold finish and two internal contact terminals. The fuse also provides other advantages such as corrosion protection and the ability to be reset after it has opened.
