BK/FLB-120 is a type of fuse which is often used in different applications for a variety of reasons. This type of fuse is an effective way to protect circuits from overloads and other faults, and provide a wide range of applications. In this article, we will look at the applications of this type of fuse and its working principle.

Application field of BK/FLB-120

The BK/FLB-120 fuse is most commonly used in electrical circuits for household appliances, such as air conditioners, refrigerators and television sets. It has also been used in the automotive industry, for applications such as tracking-engines, battery chargers, electric cars and motorcycles. In industrial applications, the fuse is commonly used to protect power supplies, relays and other control circuits. Additionally, it can be used to protect electrical devices, such as transformers, pumps, and circuits that require protection from overloads.

Apart from its traditional applications, the BK/FLB-120 fuse is now being used in other innovative ways. One example of this is the use of the fuse to protect the electronic components, like integrated circuits, from short circuits. This type of fuse is also used to protect consumer equipment from lightning, or to provide screwless terminals.

Working Principle of BK/FLB-120

The working principle of the BK/FLB-120 fuse is based on the thermal-magnetic principle. This type of fuse is designed to be responsive to both sudden current surges and sustained over-currents, and to melt quickly when the current overloads and flows through the circuit. The response of the fuse is based on the heat that is generated by the current flowing through it. When too much heat is generated, the fuse will burn through the wire, thus interrupting the circuit.

The BK/FLB-120 fuse consists of two components: the thermal element and the magnetic element. The thermal element contains the fuse wire and is the primary component that is heated by the current passing through it. The magnetic element provides an additional control to the fuse and consists of an electromagnet, which, when energized, generates a magnetic field. This magnetic field helps to reduce the current, if the current level is too high, by diverting it to a secondary circuit. This helps to protect the equipment connected to the fuse from damage.

When the current exceeds the limit, the fuse wire melts and interrupts the circuit. The current passing through the fuse can be controlled by choosing a suitable rating for the fuse. If too much current is passed through the fuse, the fuse will burn out and need to be replaced.

In conclusion, the BK/FLB-120 fuse is a versatile type of fuse and can be used in a variety of applications. With the right rating, it can provide protection against sudden current surges and sustained overloads. Additionally, it can be used to protect electronic devices from short circuits and lightning strikes.
