8BHLE-50E

Fuses

Fuses are devices that are used to protect circuits and electrical equipment from the risk of an overload. They are designed to protect from electric shocks, fire or other damage caused by excessive current. One type of fuse is the 8BHLE-50E, which is designed to provide protection in medium and high-voltage applications.

Application Field:

The 8BHLE-50E is designed to provide protection for High and Medium Voltage Medium and High Severity Applications. This includes residential, industrial, commercial, and military applications. It is also suitable for protection in areas where lights, motors, transformers, and generators are used. The rating of the 8BHLE-50E is 500V AC, rated current up to 300 A. The primary purpose of the device is to provide short-circuit protection for potential over-loads.

Working Principle:

The 8BHLE-50E operates by interrupting the electrical circuit when it detects an overload. This interruption is achieved by melting a conductive element inside the fuse, a process known as "blowing". The fuse is designed with an additional safety feature, which is the inclusion of a shunt coil. This coil acts as an additional protection for the fuse, as it suppresses the current flow and prevents it from reaching the melting point.

When the current flowing through the fuse exceeds the rated current, the fuse will activate to break the electrical circuit and protect the downstream components. The 8BHLE-50E is designed to operate quickly, reacting with a short-circuit current that can exceed 300A by several-fold. It will blow when the current exceeds its rating of 300A for more than one second.

Advantages:

The 8BHLE-50E provides a number of advantages. Firstly, it provides fast and reliable protection against excess current. Secondly, it has a wide range of applications with a maximum voltage rating of 500VAC and can be mounted in virtually any orientation. Finally, it is capable of suppressing short circuit current which is particularly beneficial for areas where motors, transformers and other heavy loads are used.

Conclusion:

The 8BHLE-50E is a powerful and reliable fuse for use in a variety of different applications. It is designed to provide fast and effective protection against over-loads and short-circuits. It has a wide application field with a maximum voltage of 500VAC. Its shunt coil provides additional safety against short-circuit current. Finally, it is easy to install and can be mounted in any orientation.
