The BK/MDA-V-5-R is a fast fusing element used for over-current protection in low voltage circuit. It is a two-piece, non-replaceable fusive device with a tolerance of +/- 0.2 s. This device is suitable for AC systems. The BK/MDA-V-5-R features low voltage drop and low energy dissipation capabilities, which allow it to effectively protect against short-circuits in AC circuits.

The BK/MDA-V-5-R consists of a fusible link and a carrier tube connected to the fusible link. The fusible link is made of silver alloy and the carrier tube is made of a heat resistant material. The fusible link is filled with a combustible powder which ignites when a specified current level is exceeded. The carrier tube contains a variety of metallic particles that serve as a medium for transfer of heat from the fusible link to the atmosphere. When the specified current level is exceeded, the combustible powder ignites and produces enough heat to melt the tin alloy in the fusible link. This triggers a chain reaction which melts the metal particles in the carrier tube and releases the heat to the atmosphere.

The device is also designed to shut off the current when the current level is too high. This is done through the use of bimetal strips that are in contact with the fusible link. The strips act as a breaker and the relay is set to the required current level. When the current exceeds this level, the strips bend and open the circuit. This activated state is maintained until the fault is corrected and the current level drops back to normal.

The BK/MDA-V-5-R has a wide range of applications. It is used for the protection of integrated circuits, transistors, and other components from over-currents. It is also used for motor overload protection and surge protection in appliances and industrial equipment. It is also used in telecommunications, where it is used as a power source protector. The device is also widely used in automobiles, air conditioning systems, and various other types of equipment.

In summary, the BK/MDA-V-5-R is an efficient and reliable fusing element used for over-current protection in AC circuits. It is designed to shut off the current when the current level is too high and to protect sensitive components from damage. The device is easy to install and maintain, which makes it an ideal choice for a variety of applications.
