Overview of Fuses

Fuses are highly effective protective devices that are widely used in a range of industrial and commercial applications to ensure safe and uninterrupted operation of electric circuits. Fuses can be broadly classified into two main types: current-limiting fuses and non-current-limiting fuses. The type of fuse used in a particular application typically depends on the application’s power rating, size, not-sustained short-circuit rating, and time-delay requirements.

0698Q2000-05 Application Field and Working Principle

The 0698Q2000-05 current-limiting fuses are commonly used in low-voltage AC power distribution applications where overcurrent protection is required. This type of fuse has a voltage rating of 400 Vac and interrupt ratings of 25kA at 30-300 Vac and 10kA at 150-400 Vac, making it well-suited for large residential and industrial circuits. The 0698Q2000-05 fuse works by limiting the current that flows through a circuit. The fuse contains a weak link of metal, usually made with a filament or wire, that melts when subjected to a current beyond its designated current limit. When this occurs, the flow of electricity is interrupted, thus protecting the circuit and any equipment connected to it from damage due to overcurrent. The 0698Q2000-05 fuse also has a time-delay feature that allows a predetermined amount of surge current to flow through the fuse before it trips. This time delay provides additional protection against surge currents, which can be caused by equipment failure, lightning, and other transient events. This feature also helps limit nuisance trips, enhancing the fuse’s effectiveness in protecting downstream equipment.

Conclusion

The 0698Q2000-05 is a type of current-limiting fuse that is ideal for low-voltage AC power distribution applications where overcurrent protection is required. Its superior current limiting characteristics, time delay feature, and not-sustained short-circuit rating make it well-suited for protecting residential and commercial systems.
