2JS 5-R Application Field And Working Principle Of Fuses

2JS 5-R fuses, a kind of fast-acting fuse, are mainly used in power circuits (in various circuits with voltage less than 500V, and in direct current and alternate current) to protect against overcurrent and short circuiting.2JS 5-R fuses are especially suitable for power protection devices, such as diesel engine controller, photovoltaic inverters, distrbution cabinets, switches, transformers, home appliances, and other current-carrying electric equipment.

The working principle of 2JS 5-R fuses is as follows: When the current in the circuit rises above the fuse’s rated current, the heating element of the fuse (wire or metal rod) begins to heat up. When the temperature reaches the pre-set melting temperature, the fuse will cut off the current, and protect the circuit from damaging.

In order to fit for various applications, the fuses come with different rating, different shape and size, various types of current capacity, and other parameters. Additionally, the 2JS 5-R fuses are also designed with various safety features, such as overload protection and short circuit protection, to ensure the safety of the equipment. The biggest advantages of 2JS 5-R fuses are:they are fast, reliable and easy to use, and they have long service life. Moreover, they are also cost efficient and energy saving. 2JS 5-R fuses are widely used in the power industry, from high-voltage power plants to residential buildings. They can provide efficient and reliable protection against overload and short circuit, and ensure the safe operation of the electric equipment.
