0229002.HXP

Fuses

Fuses are an essential component of electricity distribution systems. They are used to prevent overloads that could damage equipment or cause fires. The 0229002.HXP is a common type of fuse that is designed for use in medium- to high-voltage applications.

Application Field

The 0229002.HXP fuse is designed for use with alternating current (AC) circuits up to 12kV and direct current (DC) circuits up to 15kV. It is suitable for use in power distribution systems, motor, capacitor, and transformer circuits. It can also be used for back up protection in industrial installations.

Working Principle

The 0229002.HXP fuse is a metal-oxide varistor (MOV) type fuse. An MOV is a semiconductor device that limits overvoltage by providing a low-impedance path to ground when the voltage exceeds a certain threshold. The 0229002.HXP fuse is designed to provide protection from both overcurrent and overvoltage occurrences. When the current exceeds the threshold, the MOV will begin to conduct, reducing the voltage across it and tripping the fuse.

The 0229002.HXP fuse is also equipped with a thermal trip system that protects against overcurrent occurrences. This system is designed to open the circuit in the event of an extended overcurrent situation. The thermal trip system is calibrated to open the circuit in 12 seconds at a current of 110% of the rated current.

Advantages

The 0229002.HXP fuse is designed to be used as both primary and back-up protection for medium- to high-voltage applications. It provides fast protection against both overcurrent and overvoltage occurrences. The thermal trip system provides additional protection against extended overcurrent events. The fuse is also equipped with arc-quenching chambers that rapidly quench arc pulses to reduce the risk of fire.

Disadvantages

The 0229002.HXP fuse is not suitable for use with low-voltage applications. It must be used in conjunction with other overcurrent protection devices to provide full protection from short circuits. Additionally, it is not designed to provide protection from high-frequency interference.

Conclusion

The 0229002.HXP fuse is a type of MOV fuse designed for use with medium- to high-voltage applications. It provides fast protection against both overcurrent and overvoltage occurrences. It is equipped with a thermal trip system for additional protection against extended overcurrent events. However, it is not suitable for use with low-voltage applications and it does not provide protection from high-frequency interference.
