0678H9250-02 Circuit Protection

Fuses are essential components in the fields of circuit protective, power and energy management, and are widely used in various electronic and electrical products. They provide protection against various electrical hazards, including overloads, short-circuits, surges, and more. 0678H9250-02 is a type of fuse. As an important electrical safety device, let’s take a look at the application field and working principle of 0678H9250-02.

Application Field of 0678H9250-02

0678H9250-02 is a current-limiting, dual-element fuse suitable for high current circuit opening. It is mainly used for secondary protection of low voltage power distribution system in industry, commerce and home. Moreover, it’s widely used in computer, communication, power electronics and other electronic equipment.

Working Principle of 0678H9250-02

The 0678H9250-02 plays a role in protecting the circuit from overload, over-current and short-circuit. It is a dual-element time delay fuse. It contains one electronic element and one thermal element. The electronic element is made up of a silicon chip that is pierced through and generates a fine current. When the fuse is connected to the power line, the electric current passes through the electronic element. If the working current is too large, the fuse will generate a heat, which will cause the fuse to burn out and break the circuit.

At the same time, when a short circuit occurs, the electric current passes through the fuse very quickly, and it will pass through the thermal element of the fuse. The thermal element will absorb the excessive heat generated by the electric current, then melt down by heat. In this way, the current is cut off and the circuit is protected.

In summary, 0678H9250-02 is a high current dual-element time delay fuse, which is mainly used in the secondary protection of low voltage power distribution system. It can effectively protect the circuit from various electrical hazards, such as overloads, short-circuits and surges.
