Fuses are a type of electrical safety device that interrupts an electrical circuit when a predetermined level of current passes through it. This type of fuse is often used in the electric power industry and in industrial, commercial and consumer applications. The BK/AGC-V-1/20-R is one type of fuse that is designed to be used in general industrial applications. It is intended to protect wiring, motors, and other equipment that may be subjected to transient overcurrents. The following will describe the application field and working principle of the BK/AGC-V-1/20-R fuse.

Application Field of BK/AGC-V-1/20-R Fuse

The BK/AGC-V-1/20-R fuse is designed for use in motor control, motor circuits, and other general industrial applications, including those related to machine-type loads. It is also designed for use in 120/240V AC circuits with a maximum voltage rating of 600 volts. This fuse has an interrupting rating of 10,000 Amp AC/DC at 125/250V, and is UL recognized and CSA certified.

Working Principle of BK/AGC-V-1/20-R Fuse

The BK/AGC-V-1/20-R fuse is a thermal-magnetic type fuse that protects equipment from overcurrent and short-circuit conditions. It utilizes three distinct stages of protection: thermal trip, overload protection, and short-circuit protection. The thermal trip function is designed to protect against prolonged overcurrent events, while the overload and short-circuit protection mechanisms are designed to respond quickly to high-voltage overcurrent conditions.

When the fuse is exposed to an overcurrent or short-circuit condition, two components within the fuse will begin to heat up. The first is a bimetal strip that is designed to operate at a predetermined ampere level. When the current level reaches that level, the bimetal strip will expand and trigger the “thermal contactor,” a component that controls the flow of electric current through the fuse. Next, an electromagnet inside the fuse will be activated, and will act as a second line of defense to protect the equipment from a high-voltage overcurrent or short-circuit condition. In the event of a high-voltage overcurrent, the electromagnet will open the fuse contacts, interrupting the flow of current and protecting the equipment.

The BK/AGC-V-1/20-R fuse also has other features to help protect equipment. The fuse contacts are rated for a minimum arc voltage of 350V, which helps reduce the risk of arcing damage to the components within the fuse. In addition, the terminals are designed to prevent accidental connections to other circuit components, reducing the risk of misguided energy paths. Both of these features help to provide the best possible level of protection for the equipment.

Conclusion

The BK/AGC-V-1/20-R fuse is designed for use in a wide variety of industrial applications, due to its high-current rating and UL recognition. Its thermal-magnetic design provides both overload and short-circuit protection, and its terminals are engineered to reduce arcing risk and accidental connections. This fuse is an ideal choice for protecting industrial equipment from overcurrents and short-circuit conditions.
