Fuses are important for protecting electrical circuits and components from damage caused by excessive current, and the BK/MDL-9 is one such fuse. This fuse is mainly used in applications where control of sequencing is required, such as in air or hydraulic motor applications, and also for ignition systems. Let us take a look at the application field and working principle of the BK/MDL-9 fuse.

Application Field of the BK/MDL-9 Fuse

The BK/MDL-9 fuse is mainly used in applications where control of sequencing and overload current protection is required. It is mainly used in air or hydraulic motor applications, and in Ignition Systems. It is also used in control panels, solenoids, and other motor, relay or switch contactors. This fuse is also suitable for protecting electric motors, circuit boards, and various electrical components from overload current damage. The BK/MDL-9 is designed to provide a high level of protection, as it has an interrupting rating of 10,000 amperes at 250 volts.

Working Principle of the BK/MDL-9 Fuse

The BK/MDL-9 fuse has a metal strip that is designed to melt when an excessive current flows through the circuit. This metal strip is connected to the electrical contacts of the fuse, and it is formed in a thin rib that breaks the circuit when it melts. The metal strip is designed to melt when the current exceeds its ratings, thus preventing the current from reaching dangerous levels. The melting of the metal strip also sets off an alarm, which will alert personnel of an overload or short circuit in the system.

The BK/MDL-9 fuse also has a built-in time-delay feature, which will reduce the number of nuisance trips caused by normal inrush currents, and will also reduce false trips caused by momentary overloads. This feature helps in protecting motors and other electrical components from damage caused by inrush currents. The fuse also has a manual reset feature which allows the circuit to be reset after an overload or failure.

Overall, the BK/MDL-9 fuse is a reliable and dependable fuse that is ideal for motor applications and other applications where control of sequencing and overload current protection is required. This fuse is designed to provide a high level of protection, and it also has a built-in time-delay feature that helps to reduce nuisance trips and false trips. This fuse also has a manual reset feature, which makes it easy to reset the circuit after an overload or failure.
