Fuses are devices used for the protection of electrical circuits from overheating due to excessive current flow. The BK/MDA-V-3 is a fuse designed to protect medium voltage circuits from overcurrent failure. It has a thermal cutoff that operates when the current in the circuit exceeds the rated current. This prevents the circuit from overheating and causing excessive current flow.

The BK/MDA-V-3 is a medium voltage fuse and is designed to protect circuits from short-circuits and overloads. It is rated for a maximum of 15 kA and is capable of breaking currents up to 20 kA. The fuse consists of three main components: the thermoplastic material, the metal coil core, and the electric contacts. The thermoplastic material and metal core act as the current limiting element while the electric contacts provide the connection between the fuse and the circuit.

The BK/MDA-V-3 fuse operates on the principle of heat dissipation. In normal operating conditions, the thermoplastic material and metal core continuously convert electrical energy to thermal energy, dissipating it into the air. When the current exceeds the rated value, the thermal energy is greater than the air can dissipate. This causes the thermoplastic material to heat up and expand, eventually breaking the metal core. This interrupts the current flow and breaks the circuit.

The BK/MDA-V-3 fuse is used in a variety of applications. It is ideal for medium voltage circuits that need protection from short circuit and overloads. It is widely used in transformers, generators, electric motors, transformers, and other medium voltage equipment. It is also suitable for use in motor control centers, switchgear, and high voltage distribution systems. It is highly reliable and offers excellent protection against electrical hazards.

The BK/MDA-V-3 fuse is a reliable and economical way to provide medium voltage circuit protection. It is easy to install and maintain, requires no special tools or modifications, and can be reused after a fuse failure. Its thermal cutoff mechanism provides reliable protection against short circuits and overloads. The fuse is designed to provide safe and reliable operation at the maximum rated current. It is a cost-effective solution for medium voltage circuits that need protection from short circuit and overloads.
