Overview of Working Principle

NH00G160 fuses work in a similar way to other fuses, but have a few key differences that make them ideal for specific applications. In the case of pneumatic fuses, a gas-filled capsule is used as an interrupt element when the fuse blows. This gas-filled capsule has several chambers inside it which have a specific pressure. When the current passing through the fuse passes a certain threshold, this pressure value increases and a physical separation between the chambers inside the gas capsule occurs. This is what causes the driven capacitor to blow due to the energy released from the separation.

Advantages

The main advantage of pneumatic current-limiting fuses is the ability to withstand and help prevent damage from repeated current faults in electrical distribution systems. The high breaking capacity of these fuses ensures that even if a fault occurs, the power can be quickly disconnected and the system stabilized without any major damage. That\'s why they are ideal for critical applications such as geothermal energy plants, solar farms, and wind farms, where a slow reacting traditional fuse would not suffice.

Limitations

Given the fact that pneumatic current-limiting fuses have such a high breaking capacity, they are more expensive than traditional fuses. They also require more space and are more complex to install, making them less suitable for small-scale applications. Moreover, they require regular maintenance and inspection to ensure they are performing properly.

Conclusion

NH00G160 fuse is one of the world’s leading pneumatic current-limiting fuses, designed for quick opening, excellent current limitation, and high breaking capacity. They are ideal for a variety of mid-range current applications such as low voltage, medium voltage, domestic and industrial installations, geothermal energy plants, solar farms, and wind farms. While they are more expensive and may require more space and more complex installation compared to traditional fuses, they are well worth the investment for large-scale applications.
