Electrical and specialty fuses have a myriad of applications in commercial, industrial, residential, and municipal areas. Their purpose is to protect electrical circuits from short-circuiting, overloading, and other potential causes of damage or destruction. One of the most widely used specialty fuse is the KAJ-45. This article will discuss the KAJ-45 application field and working principle.

The KAJ-45 fuse is a medium-voltage specialty fuse with an international classification code of 600 volts. Its application field is mostly in electrical power grids, and is designed to protect the cable networks from faults. It is unique in that it has a three-phase power distribution capability, allowing it to be used in power networks with three-phase current.

The KAJ-45 operates by sensing the current in the power circuit and when the predefined value is exceeded, it open-circuits the circuit and its contacts. This can happen when a large current flows through the system or when the cable is short-circuiting. If the current overload is too large, the fuse will open-circuit the entire circuit and cut the power input. This prevents further overloading and potential losses due to high-current damage.

The KAJ-45 also has an auxiliary interrupting feature. This feature is designed to open the circuit at a predetermined level. This can prevent short-circuits from damaging electrical networks, as it will successfully open the circuit before damage can be caused. This is an important feature for preventing the overload of power networks in both large-scale and small-scale applications.

One of the most important advantages of the KAJ-45 fuse is that it is designed to protect power networks from a wide variety of risks. Its three-phase power distribution capability can protect networks from overloads in any combination of three-phase currents. Its auxiliary interrupting feature protects networks from short-circuits, while the overload protection feature protects networks from current overloads.

Finally, the KAJ-45 has a very high breaking capacity, which ensures that it will open the circuit before any damage can be done to the power cables. This makes it a great choice for power electrical networks of any size, from residential to industrial.

In conclusion, the KAJ-45 is a great specialty fuse for power electrical networks, due to its capacity to protect against overloads, short-circuits, and other potential risks. Its three-phase power distribution capability gives it an advantage in this application field, and its high breaking capacity ensures that it will open the circuit before any damage can be done to the power cables. All in all, the KAJ-45 is an essential tool for power electrical networks.
