A fuse is an electrical device that is used to protect an electrical circuit from damage caused by the flow of excess current. Disconnecting the circuit whenever an overload is detected, it prevents further damage to the components of the system. The BK/FLB-40 is an over-current protection device designed for use in a wide range of commercial and industrial applications.

The BK/FLB-40 consists of two main components: a trip unit and fusible link. The trip unit is equipped with a thermal fuse which is triggered to open the circuit when the current flowing through the system exceeds a preset threshold, thus protecting against over-loading.

The trip unit is also equipped with a time delay feature which allows the circuit to stay open for a predetermined length of time depending on the current overload level. This feature reduces nuisance tripping due to short power surges or transient overloads. The trip unit is self-contained and sealed, making it impervious to dust, dirt and moisture.

The fusible link of the BK/FLB-40 is constructed of a special alloy of copper and nickel that has been designed to melt at a predetermined temperature. This prevents damage to the components from the flow of excessive current.

The BK/FLB-40 is designed for use in industrial, residential, commercial, and institutional applications where over-current protection is required. It is suitable for use in panel boards, industrial control systems, and other applications where an overload needs to be detected and prevented.

The BK/FLB-40 offers reliable over-current protection with superior time-delay performance. It features a modular design, making it easy to install and replace. It also offers a range of current ratings to suit various needs.

In summary, the BK/FLB-40 is a high-quality over-current protection device designed to provide reliable over-current protection in a wide range of commercial and industrial applications. It features a thermal trip unit and an alloy fusible link for superior protection against overloads. It is easy to install and replace, and is suitable for various current ratings.
