0312.300H Application Field and Working Principle

Most of the time, a fuse is used in circuit protection. A fuse is a safety device that interrupts the circuit to prevent heavy short-rust, over-heat and overcurrent protection. The 0312.300H type safety fuse is a type of fuse that is designed for medium voltage. It can be used in a variety of related applications.

Applications of 0312.300H type safety fuse can be divided into four main areas: high voltage transmission and distribution, transformers, electrical motor and other component protection. The fuse is particularly suitable in applications where heavy short-circuits and over-heat are likely, such as high voltage line protection.

As a medium-voltage fuse, the fuse can withstand high current up to 25 kA. This type of fuse can interrupt a short-circuit at up to 20 times its rated current. This makes it ideal for applications where protection is necessary from heavy short-circuits and over-heat.

The working principle of the 0312.300H type safety fuse is simple but effective. When the current in a circuit rises above the rated current of the fuse, the fuse element will begin to heat up. This heat will cause the fuse element to melt, which will then cut the circuit. This is the safety mechanism that prevents the potentially harmful effects of over-heating and heavy short-circuits.

The fuse is designed to be reusable after being blown. After the fuse has been reset, it can be used again once the circuit has returned to its normal operating conditions. As the fuse can be easily reset, it is an ideal medium voltage protection device for any application.

In summary, the 0312.300H type safety fuse is a medium voltage fuse that is designed for a variety of applications. It can be used in high voltage transmission and distribution, transformers, electrical motor and other component protection. The fuse is designed to cut the circuit in the event of over-heat or heavy short-circuit. It is also designed to be reusable after being blown. As the fuse can easily be reset, it is an ideal protection device for any application where medium voltage is necessary.
