JJS-450

JJS-450 Application Field and Working Principle

The JJS-450 series is an industrial special fuse mainly used for non-critically application in industrial electronic automation equipment, such as infeed, transfer, spinning, twisting and snipping machines, spinning machines, and other electronic control systems. The purpose of using a fuse is mainly to protect other circuits from over-current and short circuit. The JJS-450 series fuse has a wide range of current ratings, and is made of Low Pressure Vacuum Interruption (LPVI), which is reliable and safe.

Working Principle

The JJS-450 series fuse is type of thermal fuse. It is designed to protect the electric circuit to cut off current automatically when the circuit is overloaded or has a short circuit. The fuse is made from LPVI technology. LPVI technology is the most mature technology in fuse products, which utilizes the vacuum generated by the arc inside the fuse element to enhance the fuse’s interrupting capability and interrupting time stability.

Once the fuse is overloaded or has short circuit, the breaker quickly eliminates the electric arc and the accompanying heat melts down the fuse element. The explosive pressure of the fuse element determines the speed at which the fuse element is destroyed. The LPVI technology helps reduce the explosive pressure of the fuse element, which is beneficial for the electrical devices and increases the reliability of the fuse.

Features

The JJS-450 series fuse has several features that make it different from other fuses. First, the LPVI technology allows the fuse to have fast response time and high interrupting capability. Secondly, the casing is made of rigid plastic, which is resistant to shock and vibration, and provides excellent protection in challenging environments. Third, the JJS-450 series fuse has a wide range of current ratings ranging from 0.4A to 3.0A, making them extremely flexible and suitable for different applications.

The JJS-450 series fuse is also very easy to install, as it fits into PCB holes. It has two independent wires with hook-up, and a solder cup to make the connections easier. Moreover, it has a unique visual endcap, which identifying the rating of the fuse and helps to indicate when the fuses are suffering from aging.

Applications

The JJS-450 series fuse is primarily used in industrial electronic automation equipment. It is suitable for non-critical applications such as controlling, transferring, spinning, twisting, and snipping machines. It is also an ideal solution for spinning machines and other electronic control systems. The JJS-450 series fuse is designed for applications where ultra-short response time is required. It can also function as a DC fuse disconnector for sensitive electronic circuits.

In addition, the JJS-450 series fuse can be used in DC circuits with a voltage rating up to 50V. It is an extremely reliable fuse and is proven to withstand surge voltages without tripping. With the right selection, the JJS-450 series fuse can provide reliable protection for a wide variety of electronic applications.
