Electric arc is a dangerous component in electrical energy systems, and fuses are the first line of defense in protecting the equipment and personnel from potentially catastrophic events. BK/MDQ-3/4 are one of the most widely deployed fuse solutions and trusted members of the fuse family. This article will discuss the application field and working principle of the BK/MDQ-3/4 fuse.

BK/MDQ-3/4 fuses are applicable in numerous locations including high power installations including motors, transformers, substations and switchgear. All of these may be susceptible to over-current conditions and thus the use of a fuse to protect them is crucial. Electromagnetic circuit breakers are also used in these applications, but often a fuse offer a simpler, cheaper and more reliable current limitation solution.

The working principle of the BK/MDQ-3/4 fuse is based on the fact that, when an over-current passes through the fuse element, the heat generated by the electrical arc causes the fuse element to melt. This throws a switch that disconnects the equipment from the power supply, preventing continued arcing and short circuits. The fuse therefore safely and reliably channels the excessive current away from the equipment.

One of the major advantages of the BK/MDQ-3/4 fuse is that it is a link-type fuse, meaning that it can be used to isolate individual components within an application. This is especially useful in installations such as motor primaries where disconnection of one side of the motor can be isolated very quickly and safely using a fuse. This allows the other side to remain energized while the technician works on the other side of the system.

Due to its high performance and reliability, many manufacturers specify the BK/MDQ-3/4 fuse as a form of protection in their products. The fuse is also UL, CSA and CE listed and tested and certified according to IEC standards, making it an unbeatable choice for many applications. Moreover, since its introduction in the 1970s, the fuse has become one of the most widely deployed fuse solutions in the world.

The BK/MDQ-3/4 fuse is an invaluable asset in providing reliable circuit protection in a variety of electrically demanding applications. The fuse is simple to install and just as easy to replace. With its high current rating and its ability to reset without trip, the BK/MDQ-3/4 fuse is an unbeatable option when it comes to protecting applications with high power requirements.
