0JTD01.5TXID Datasheet/PDF0JTD01.5TXID application field and working principle
0JTD01.5TXID is a type of medium voltage current limiting fuse, applied in the application fields of AC cable line, power capacitor, and transformer protection against over current up to 145kVA. It is a good choice for transformer protection when as the rated voltages are lower than 6-12kV in electric power distribution systems. With the features of long operating time when the over current incurs and small arc current, it has been widely used in lower voltage grids all over the world.
The working principle of 0JTD01.5TXID is mainly based on the melting of wire. It consists of a metal strip connecting between two pins on the fuse body. Inside the strip, there is a silver wire acting as the fuse element. When an over current occurs, the electrical current will flow through the fuse element and the wire starts to heat up. Once the temperature is high enough, the wire will melt and the fuse element will be broken by the current.
Once the fuse element is broken, the circuit is broken and the current is interrupted. The heat generated by the current is absorbed by the fuse body, the air and the cooling surface. The steps are fast enough to keep the circuit from getting over heated and damaged. The fuse will cool down and recover its original state.
The 0JTD01.5TXID is designed with an advanced fuse element to improve its performance. It can withstand a higher temperature and also limit the arc current, so that it works better in a greater range of over current. The fuse body is made of high quality ceramic with a black zinc-plated copper cover, providing superior corrosion protection and durability.
In conclusion, the 0JTD01.5TXID is a reliable medium voltage current limiting fuse with its special application fields and working principles. It is widely applied in the lower voltage grids all over the world to provide a safe and reliable power supply environment. With the features of long operating time when the over current incurs and small arc current, it is an excellent choice in the field of medium voltage protection.
