Fuses

Fuses, also known as fuses or circuit breakers, are an important protective component for electrical and electronic products. The fuses used in the industry mainly include fuse cartridges, fuse blocks, and fuse holders. The installation of 15BHLE-50E is very common. This article will discuss the application field and working principle of 15BHLE-50E

Application Field of 15BHLE-50E

15BHLE-50E is a fuse with excellent overload and short circuit protection performance. Its application field is mainly applicable to the secondary electrical system of the power distribution system operating at 50HZ and below. The rated voltage of the electric system is not more than 400V. The maximum rated current of 15BHLE-50E is 50A. It is suitable for large-capacity overload protection of circuits and short-circuit protection of electrical systems.

Working Principle of 15BHLE-50E

The working principle of 15BHLE-50E is to automatically open the circuit when the load current exceeds the rated current. With the rise of the circuit current, the conductor gradually begins to heat up and melt, and the electric current of the circuit is disconnected. When the circuit current is lower than the tripping current, the conductor returns to a normal state and the circuit is re-energized.

When the 15BHLE-50E is in a quenched state and needs to be reinstalled, the fuse rod needs to be replaced. At this time, the switching on and off of the circuit needs to be done separately. First, turn off the power supply of the circuit and remove the fuses of 15BHLE-50E and then replace with new ones. Then turn on the power and install. The 15BHLE-50E fuse is very important in the loop protection. Its protection effect depends largely on its installation and the correct selection.

Conclusion

15BHLE-50E is a common fuse in industrial production and very important for circuit protection. It is mainly applied in the secondary electrical system of the power distribution system at 50HZ and below, with a maximum current of 50A. Its working principle is that when the circuit current exceeds the rated current, the fuse rod will heat up and melt, thus breaking the circuit and achieving the purpose of protecting the circuit. These are the basic principles and application fields of 15BHLE-50E.
