20111250531P Application Field and Working Principle

Fuses are electrical products used in all kinds of electrical devices. The application fields of fuse type 20111250531P mainly includes protecting communication line, high voltage secondary distribution switch equipment and other electrical devices from short circuit or overload. Fuses are suitable for AC 50/60Hz, rated voltage 690V, rated current up to 200A.

The basic working principle of fuse type 20111250531P is that when it encounters an electrical overcurrent, the fuse element, which is made of highly conductive metals such as tin or copper, will be heated up and melted, thus breaking the circuit and cutting off the current to protect the power line and device. Fuse is a current-limiting device, it blocks large current but lets small current pass through.

Fuse type 20111250531P can be divided into three types according to different functions.The first type is DIN type fuse cutout. It is mainly used in secondary distribution line with rated voltage range of 12KV-35KV and rated current up to 200A. It provides short-circuit protection, overload protection and high current limit protection.The second type is fuse cutout with current limiting. This type is also mainly used in secondary distribution line with rated voltage 12KV-35KV and rated current up to 200A. Its main function is to limit and protect the system operation and personnel safety.

The third type is busbar coupling fuse. It is suitable for integration of all kinds of circuit protection, mainly used in electric substations and switching equipment. It can also control the current effectively and can be used with protection equipment.

In addition, fuse type 20111250531P also has other characteristics such as long service life, low energy loss and reliable operation. As for the wiring of the fuse type 20111250531P, it is very important. The wiring should be done according to the wiring diagram and the regulations of the fuse manufacturer.
