BK/GBB-15-R

Fuses are devices that protect electrical equipment and circuits from excess current by opening the circuit to halt the flow of electricity. The BK/GBB-15-R is a type of fuse which is designed primarily for residential and commercial applications. It is a cylindrical, ceramic class RK-5 fuse, rated at 15 amperes, though these ratings can vary according to the manufacturer.

The body of the fuse is made of ceramic and encased in plastic. The fuse element is contained within a sheath-like part that is either glass or synthetic fiber-based. The fuse element has a metal strip running through it that connects the two prongs on either side of the fuse. This metal strip is able to expand and contract as the current through it changes, in turn allowing the fuse to trip when a certain current level is exceeded.

The BK/GBB-15-R fuse has a maximum interrupting capacity of 10,000 amps and operates in temperatures ranging from 32°F to 140°F (0°C to 60°C). It is also current sensitive, meaning that it will open the circuit when a predetermined current level is exceeded, usually ranging from 5 to 10 times the rated ampere rating of the fuse. The fuse has a UL, or Underwriters Laboratories, E38165 certification.

The type of BK/GBB-15-R fuse is particularly suitable for applications in residential and commercial settings such as distribution panels, junction boxes, and appliance outlets. It is designed to protect against overcurrent of 15 amperes or less and features a quick blow response time of 0.05 seconds. This type of fuse is also suitable for protecting inductive circuits, like those found in electric motors, and other type of circuits that generally require a higher level of protection than that provided by a standard time delay fuse.

In operation, the BK/GBB-15-R fuse works by allowing current to flow through it, causing the metal strip within it to expand as the current increases. When the current surpasses a certain level and reaches the predetermined interrupting capacity, the strip will snap, opening the circuit and effectively halting the flow of electricity. This allows for the quick reduction of hazardous currents that may originally have exceeded the safe operational levels of the equipment.

The BK/GBB-15-R fuse can also be used in combination with other types of circuit breakers and fuses to provide additional levels of protection for certain circuits. In addition, this type of fuse is relatively small, making it well-suited for use in tight spaces. Furthermore, thanks to its fuse element, this type of fuse offers a high level of repeatability, making it an ideal choice for situations where it is important to have fuses that operate consistently and reliably.

Overall, the BK/GBB-15-R fuse is an ideal choice for residential and commercial applications that require protection against overcurrent or high levels of current. Its UL certified design and current sensitivity makes it an ideal choice for protecting circuits from excess current. In addition, its small size and high level of repeatability makes it ideal for use in tight spaces or circuits requiring a high degree of consistency.
