BK/MDL-V-4/10

Fuses are important components in electrical systems that are designed to "open" (i.e., create an open circuit) when a certain current level is reached or exceeded for a specified period of time. The BK/MDL-V-4/10 is a fuse used for medium voltage applications.

The fuse consists of two parts: the fuse element and the fuse holder. The fuse element is made of a high-current resistant, ceramic-filled material that will not oxidize or corrode, making it highly reliable when compared to traditional fuse materials. It is also designed to be resistant to thermal shock, making it more durable in applications subject to frequent high-current surges. The fuse holder consists of an insulating housing with two current-rating contacts that connect to the fuse element. It also has a pin connector for easy connection to other components, such as circuit breakers.

The BK/MDL-V-4/10 fuse is designed for medium voltage applications, with a maximum voltage rating of 4 Mohm in 10A applications. It is suitable for use in circuit protection applications such as motor controls, power supplies, transformers, and other high-current electrical systems. The fuse has a continuous current rating of up to 10A and a minimum breaking capacity of 18kA. It has a 200 millisecond interrupting rating, meaning it is able to withstand up to 18kA of current for 200 milliseconds before opening.

The working principle of the BK/MDL-V-4/10 is based on the principle of an overcurrent protection device. When a current greater than the rated limit flows through the fuse, the fuse element gets heated up and starts to melt. This melts the insulation around the fusing current, allowing a connection between the two parts of the fuse and thus "breaking" the circuit. The BK/MDL-V-4/10 also has a low recovery time, so the circuit can be restored as soon as the fault current is removed.

In conclusion, the BK/MDL-V-4/10 is a highly reliable, medium voltage fuse with a continuous current rating of up to 10A and a minimum breaking capacity of 18kA. It is suitable for use in circuit protection applications such as motor controls, power supplies, transformers, and other high-current electrical systems. The fuse has a 200 millisecond interrupting rating and a low recovery time, making it an ideal choice for applications where reliable circuit protection is needed.
