BK/S504-80MA Application Field and Working Principle

Fuses are a device used when wiring electrical systems. Their role is to prevent overheating or shorts from damaging the wiring or system components. In addition, they also protect against too much current from flowing which can lead to accidents. The BK/S504-80MA is a fuse designed specifically for AC and DC systems. This article will discuss the application field and working principle of BK/S504-80MA.

Application Field of BK/S504-80MA

BK/S504-80MA is a three-pole fuse that is used in AC and DC systems. It is capable of withstanding 1500 V AC and over-voltage UL listed. It is ideal for use in automotive and industrial applications as well as medical applications. Additionally, it can be used in motor protection, DC, power distribution, and other applications.

BK/S504-80MA has a variety of mounting options. It can be mounted on the DIN rail, chassis, and panel mountings as long as the voltage ratings match. It also features a black ceramic body for high insulation resistance and resistance to aging. The fuse has a UL/ULC approved rating of 8A and a maximum voltage of 1500V AC/DC.

BK/S504-80MA is also UL489 (low voltage) listed, which means it is certified for both AC and DC systems. This makes it ideal for a wide range of applications, from low voltage power supplies to telecommunication systems. It is also RoHS compliant.

Working Principle of BK/S504-80MA

The BK/S504-80MA fuse works in two ways. It acts as a thermal overload, providing protection when the current flows are higher than expected. Additionally, it acts as a short circuit, limiting the current when short circuits occur.

When the current exceeds certain limits, the filament inside the fuse melts. This melts the metal contacts inside the fuse, causing an open circuit. As a result, the current is cut off and the fuse “blows”. This interrupts the flow of current, thus preventing damage to the system or components.

Fuses can also provide protection against over-voltage. When the voltage exceeds a certain value, the fuse acts as an open circuit, blocking the current. This is important in preventing components from being damaged due to over-voltage.

The BK/S504-80MA fuse has a high voltage rating and can withstand temperatures up to 125 degrees Celsius. This makes it suitable for use in high temperature environments. In addition, it is also UL489 listed, meaning it is approved for use in AC and DC systems.

Conclusion

BK/S504-80MA is a high-performance fuse designed for use in AC and DC systems. It is capable of withstanding 1500V AC and has a UL/ULC approved rating of 8A. It provides protection against thermal overloads and short circuits. Additionally, it can provide protection against over-voltage. It is suitable for use in automotive, industrial, and medical applications, and is approved for use in UL489 (low-voltage) systems.
