BK/MDA-BV-20-R

Fuses are special types of electrical devices used to protect equipment by automatically disconnecting electrical circuits when a protection requirement is met. The BK/MDA-BV-20-R fuse is a blow-out type current limitation fuse specifically designed to limit the amount of current that can flow through it. It is designed to protect against excessive current and is ideal for use in telecommunications, signaling and control applications.

The BK/MDA-BV-20-R fuse is a special type of fuse that is composed of a metal element between two metal caps and a ceramic body. The metal element is designed to expand when exposed to excessive heat, which causes an arc between the two metal caps and results in an immediate interruption of the flow of electrical current.

The BK/MDA-BV-20-R fuse is designed primarily for use in 600Vdc applications, with a back-of-panel mounting system. Its maximum allowable current is 20A and it operates with a maximum limiting current of 10A. It is also designed to withstand high short-circuit currents without damage.

The BK/MDA-BV-20-R fuse also features a self-resetting fuse, meaning that the fuse will reset itself when the fault is cleared. This feature eliminates the need to manually inspect or replace the fuse. The fuse also has an LED indication system, which is useful for quickly spotting blown fuses without having to open the panel.

The working principle of the BK/MDA-BV-20-R is simple and straightforward. The fuse consists of two metal contact elements, one connected to the supply and the other to the load. When a fault or an overload current passes through the fuse, it triggers an arc which heats up the metal disc held between the two contact elements and causes it to expand and eventually separate, breaking the circuit and stopping the flow of current.

The BK/MDA-BV-20-R fuse is a versatile and reliable product that provides reliable and fast over-current protection for 600Vdc applications. It is commonly used in telecommunications, power distribution and control systems. With its LED indication and self-resetting fuse feature, the BK/MDA-BV-20-R helps to make any electrical system more efficient and safer.
