Fuses

022502.5H application field and working principle

Fuse is a current-limiting device used in circuit protection, which plays the role of protecting the circuit when it is overloaded, short-circuited and instantaneous overvoltage. The type 022502.5H is a glass body slow-blow type fuse, which is suitable for unipolar power supply and AC power supply protection circuit of household and similar electrical equipment. The Fuse will breaking the circuit when the current exceeds a certain level and protect the circuit from fire and electric shock.The 022502.5H fuse can also be extended to fuse a wide range of products, such as air conditioner, washing machine, refrigerator, lamps, electronic components and more. The slow-blow fuse ensures that inrush current such as start-up current is within safe limits and does not damage equipment and cause component failure.The working principle of the 022502.5H fuse is to rapidly melt the material with a large current at the moment of overcurrent or short circuit, thereby cutting off the circulation of the current and achieving the purpose of circuit protection.The 022502.5H fuse consists of a fuse core, a cap, a fuse body and a support bracket. The fuse core is made of alloy material. When the ambient temperature is below 125 ℃, the fuse core can be operated correctly under normal current, and it will be current-limiting and cut off when the current rises rapidly by an abnormal setting.The fuse cap is used to insulate, protect the fuse body from external damage and prevent accidental contact with the fuse core. Its sealing ring is also used for internal sealing to ensure that air and dust do not enter the fuse body during actual use.The fuse body uses the shape of a glass container. The lead end at the side of the fuse core is connected outside the circuit. In actual use, the hold down bracket is put on the outside of the fuse body, and the fuse is tuned to the maximum rated current.In summary, the 022502.5H is suitable for unipolar power supply and AC power supply protection circuit of household and similar electrical equipment. The working principle of the 022502.5H fuse is to rapidly melt the material with a large current at the moment of over-current or short circuit, thereby cutting off the circulation of the current and achieving the purpose of circuit protection, which is the most complete and safe protection method.
