BK/S500-100-R

Fuses are electrical components used in various applications to protect circuits and equipment in the event of an overload or short condition. The BK/S500-100-R is a type of fuse used for medium and low voltage applications. Its broad range of features make it a suitable product for a wide variety of applications. This article will discuss the application fields and working principle of the BK/S500-100-R.

Application Fields

The BK/S500-100-R is a medium and low voltage fuse designed for applications in turbines, transformers, motors, and reactors. It is used to prevent damage to the circuits and systems by providing an overload and short circuit protection. The fuse can be applied to both AC and DC systems, with an operating voltage of up to 600V AC and up to 1000V DC. It also has an interrupt rating of up to 100kA.

In addition to its use in medium and low voltage applications, the BK/S500-100-R can also be used in high voltage applications. With a maximum voltage rating of 690V AC, the fuse is ideally suited for use in high voltage electrical distribution hotsticks, switchgears, and other high voltage electrical systems. The fuse also has a thermal rating of up to 100% of the current carrying capacity, which means it can handle higher sustained overloads with minimal risk of failure.

Working Principle

The BK/S500-100-R works by providing a physical barrier that melts when the current passing through it exceeds the specified rating. When the current rating is exceeded, the heat generated by the current causes the fuse element to change shape and break the circuit. The fuse also acts as a thermal fuse, which means that it will trip if the temperature of the fuse element exceeds its specified rating. This serves to protect the circuit from thermal overloads that could occur due to a current overload.

The fuse also acts as an electrical fuse, which means that it will trip if the voltage across the fuse exceeds the specified rating. When the fuse trips due to a voltage overload, it will cause the circuit to open and stop the flow of current. This serves to protect the components from overvoltage and will also stop any fire or shocks from occurring.

In addition to providing overload protection, the BK/S500-100-R also provides short circuit protection. It is designed to sense when a short circuit occurs and will trip to break the circuit in order to protect the components from the high current. The sensitivity of the fuse can be adjusted depending on the application, allowing for protection in a range of scenarios.

Conclusion

The BK/S500-100-R is a fuse designed for medium and low voltage applications. Its broad range of features make it suitable for use in a variety of applications, including turbines, transformers, motors, and reactors. The fuse works by providing an overload and short circuit protection, as well as voltage and thermal protection. By protecting the circuit from overloads, shorts, and other dangerous scenarios, the BK/S500-100-R helps to ensure the safe and efficient operation of the circuit.
