BK/GMW-5

The BK/GMW-5 Fuse is a blade-type fuse made of metal-oxide designed to provide overcurrent and overload protection. It is mainly used in electronic circuits for telecommunications and medical equipment, as well as consumer appliances and light-duty power circuits. The fuse is also suitable for application in vehicles, such as automobiles and motorcycles, and industrial electronics.

The BK/GMW-5 fuse is composed of a central metallic strip that acts as its main conductor and is covered with a layer of special ceramic material. The metallic strip is connected to two terminals and contains an overload protective element. The ceramic material is designed to prevent overheating and premature aging of the fuse, as well as to ensure an extremely fast reaction time in case of an overcurrent or overload. The fuse has a rated voltage of 250V and a current rating of 5A.

The main function of the BK/GMW-5 fuse is to protect the circuit from excessive current by either melting or breaking the circuit. If too much current passes through the circuit, the metallic strip will heat up to a temperature that will cause it to melt or rupture, thereby interrupting the circuit and preventing further damage. The fuse is also designed to react immediately and allow the passage of a normal current through the circuit.

The working principle behind the BK/GMW-5 fuse is based on the temperature-sensitive behavior of the conductive element contained within the fuse. As current passes through the metal strip, it causes the temperature to increase until it reaches the fuse’s melting point. At this point, the metal strip will melt and the circuit will be broken. The reaction time of the fuse is very important in order to prevent too much current from passing through the circuit, and the BK/GMW-5 fuse is designed to react as quickly as possible when the temperature of the metal strip exceeds its melting point.

As with all fuses, it is important to select the appropriate fuse for the specific application. Overcurrent and overload protection are both important considerations when selecting a fuse, as well as the size and type of the circuit, the number of poles, and any other applicable requirements. It is also important to select the correct amperage rating for the fuse, which should be equal to or greater than the amperage rating of the circuit it is placed in.

In conclusion, the BK/GMW-5 fuse is a versatile safety device that provides overcurrent and overload protection in a wide variety of applications. It is composed of a metal-oxide-coated conductive element that is designed to melt rapidly when it exceeds its melting point. The fuse is suitable for use in telecommunications, medical, consumer electronics and automotive applications, as well as in industrial electronics. It is important to select the correct size and type of fuse for the application, as well as the correct amperage rating, in order to ensure the safety of the circuit and its components.
