BK/A304-2A

Fuses refer to the devices used in circuits to protect electrical circuits from overload, short circuit and other electrical faults or transient overvoltages. The BK/A304-2A is a type of fuse widely used in many applications. In this article, the application fields and working principle of this fuse will be discussed.

Application field

The BK/A304-2A is mostly applied in power electronic equipment, switchgear systems, and the protection of low voltage power supplies. It is especially suitable for the cases where both isolation and current limiting capacity is required. This fuse is also used in the protection of communication networks, low voltage industrial equipment, electronic processing equipment with high frequency, and many more. Other applications include the protection of equipment with low internal impedance, such as diodes, silicon controlled rectifiers, thyristors, NTC temperature sensors, etc.

Working principle

The working principle of the BK/A304-2A follows the basic principle of all fuses. It utilizes two current-carrying components arranged in series. When an overload occurs, the current will exceed the fuse’s rated value, thereby heating up the fuse components. When the temperature of the components reach a certain limit, the fuse will break the circuit to limit the current. By breaking the circuit, the fuse will provide protection to the circuit, thereby preventing circuit damages.

In terms of current-limiting capability, the BK/A304-2A is designed to provide a fast response time. When an overload occurs, it can break the circuit in a matter of milliseconds. This reduces the possibility of circuit damages, as the current is quickly limited and the associated device is protected. Furthermore, this fuse is also designed to have a high breaking capacity, which ensures the reliability of the circuit protection.

In conclusion, the BK/A304-2A is a versatile and reliable fuse for many applications. It can provide an effective and fast protection to circuits, thus preventing short circuits and circuit damages. Therefore, this fuse type is a popular choice for many applications.
