Introduction: What is BK/MDA-2/10-R?

The BK/MDA-2/10-R is a fuse, also known as medium voltage fuses, for use in medium voltage power distribution systems. Medium voltage fuses are used to protect electric circuits with nominal voltages exceeding 600 volts but not as high as the tension of transmission lines. This type of fuse is designed to be used in combination with circuit breakers, the fuses consuming the fault current when in operation.

Applications of BK/MDA-2/10-R

BK/MDA-2/10-R fuses are commonly used in applications such as:

• Induction and Synchronous Motors.
• Distribution Feeders.
• Transformers.
• Generator Town Power Connections.
• Front Exterior of Buildings.
• Power Distribution Units.
• Main Supply Panels.
• Building Mains Distribution.

The BK/MDA-2/10-R fuses are designed for the protection of insulated and cable-connected low voltage to medium voltage circuits against over-current faults and it provides the advantage of improved reliability against overload and short circuit conditions.

Working Principle of BK/MDA-2/10-R

The BK/MDA-2/10-R fuses are designed to operate in two different ways. They can be used either as a overload protection device or as a short-circuit protection device, depending on the application. When a current separation is required, the BK/MDA-2/10-R fuse is used as a overload protection device, protecting against long-term over-current faults and providing separation between the power sources. When the fuse reaches the current threshold, it will open the circuit breaking the connection between the two power sources.When the BK/MDA-2/10-R fuse is used as a short-circuit protection device, it is designed to protect against short-term over-current faults. When it reaches the current threshold, it will blow, interrupting the power-flow from the power source in order to protect the system from further damage.

Conclusion

The BK/MDA-2/10-R fuse is a type of medium voltage fuse designed for use in medium voltage power distribution systems. It is designed to provide overload and short-circuit protection in order to ensure reliable operation of the system. It is commonly used in applications such as induction and synchronous motors, distribution feeders, transformers, generator town power connections, etc. The fuse operates by either opening the circuit when a current threshold is reached or by blowing when a high current threshold is passed.
