0NLN004.T

Specialty fuses are an important part of any electrical system. They protect the system from overcurrents due to surges or short circuits. The 0NLN004.T is a type of specialty fuse specifically designed to protect low voltage DC applications such as solar photovoltaic panels. This article will discuss the application field and working principle of the 0NLN004.T fuse.

Application Field

The 0NLN004.T fuse is designed for use in low voltage direct current (DC) applications, such as solar photovoltaic panels. It is designed to provide protection from the high levels of current these systems could be exposed to in the event of an overvoltage or short circuit. It is particularly suited for array protection, as it allows for increased system reliability and flexibility. Additionally, it is important to note that these fuses are perfect for both indoor and outdoor applications due to their robust design and ability to cope with wide temperature ranges.

Working Principle

The 0NLN004.T fuse works by interrupting the circuit when an overcurrent is detected. The fuse works by using a metal conductor surrounded by a ceramic or silica body. This then contains a special alloy metal element located in a central void. When or if the current in the circuit exceeds a certain level, the element melts and this breaks the connection between the two points of the circuit. This then opens up the circuit, preventing further flow of current.

The 0NLN004.T fuse has a rated operating voltage of up to 600 V DC. It also has a very fast tripping time, as well as a high current rating of 200A and an interrupting rating of 30kA. The metal conductor in the 0NLN004.T fuse can also be changed to a copper conductor, making it even more effective.

Conclusion

The 0NLN004.T is a specialty fuse designed for low voltage DC applications such as solar photovoltaic panels. It works by interrupting the circuit if the current exceeds a certain level, thus providing protection against overcurrents due to surges or short circuits. It is perfect for both indoor and outdoor applications, and has a rated operating voltage of up to 600 V DC with a current rating of 200 A and an interrupting rating of 30 kA.
