Fuses are safety devices often used in electronics, as they can help in the prevention of system damage or failure from abnormal current and voltage levels, and are often used to protect circuit components or systems. One such fuse is the 0678H1250-02, which is a standard Time Delay Class G 20 ampere fuse.

Application Field

The 0678H1250-02 Time Delay Class G 20 ampere fuse is suitable for overcurrent protection of power supply lines, motor circuits and other electronic circuits. It is designed to prevent overcurrent damage caused by short circuit, overload, and single-phase. It is primarily used for residential surge protection to protect computer and electronic equipment from the damaging effects of improper power.

Working Principle

The working principle of the 0678H1250-02 Time Delay Class G 20 ampere fuse is to rapidly detect and cut off the overcurrent whether it is a short circuit or overload, so as to protect the downstream circuits or equipment from being damaged. The 0678H1250-02 fuse is triggered by a preset current level, which can also be set to protect the system from momentary or transient overloads. This fuse has two operating states: normal and open. When the fuse is in the normal state, the current passes through the fuse uninterrupted; when the operating current exceeds the preset limit, the fuse trip and becomes open, separating the circuit and preventing the circuit and its components from being damaged.

Conclusion

The 0678H1250-02 Time Delay Class G 20 ampere fuse is an important device used for overcurrent protection for electronic circuits, and is commonly used to protect computers and other electronic devices from damage caused by improper power. Its working principle is to quickly detect and cut off overcurrents, which makes it a highly effective protection device. With its wide range of applications, the 0678H1250-02 is an invaluable addition to any electrical circuit.
