KAB-1/2 Application Field and Working Principle

KAB-1/2 Fuses have made an outstanding contribution in the field of electrical protection. This fuse has several merits and features that make it an ideal choice for applications in power systems. In this article, we will discuss the application field and working principle of the KAB-1/2 fuse.

KAB-1/2 Fuse Description

KAB-1/2 Fuses are non-current limiting, low voltage fuses. The current limitation of these fuses is 16A, however, they can be used up to 32A. These fuses come in both complete-range cylindrical models and plug-in style models. All of these models meet UL, CSA, IEC, and other international safety standards. The KAB-1/2 Fuse is designed with a hollow-core wire material that permits a low melting temperature with pre-assembled leads. Since there is no need for a terminal block with this type of fuse, some of the models come with a self-extinguishing case for additional protection.

Application Field of KAB-1/2 Fuse

KAB-1/2 Fuses are primarily used in applications involving high-level protection needs. They can be used in any type of system that requires electrical protection, such as a power system, an industrial control system, a lighting system, or a vending machine. KAB-1/2 fuses can also be used in battery-powered devices, as they have a very low resistance voltage drop.

KAB-1/2 Fuses are a great choice for fire protection, as they have a high short-circuit rating and a rapid response time to any short circuit. They also provide excellent surge protection with their UL Class T0-fuse body. In addition, they are ideal for applications in tough and hazardous environments, due to their high mechanical strength and current limiting characteristics. They are also able to withstand high currents without any damage.

Working Principle of KAB-1/2 Fuse

The KAB-1/2 Fuse is designed with a non-current limiting element which is inserted in a hollow-core wire. When the current flowing through the wire reaches a certain level, the fuse will heat up and melt. The melting of the fuse will disconnect the current from the circuit, allowing it to remain protected.

KAB-1/2 Fuses are also designed with a unique fuse clearing ECU. This ECU senses any current flow through the fuse and then automatically clears the fuse when it reaches the pre-set current level. The fuse-clearing ECU reduces the risk of an unnecessary circuit trip by allowing the current to travel to the fuse without ever interrupting the circuit.

Conclusion

KAB-1/2 Fuses have proven to be an invaluable option in the field of electrical protection. Their non-current limiting feature, their low voltage drop, and their quick response time make them an ideal choice for high-level protection, particularly in power systems and hazardous environments. In addition, their fuse-clearing ECU reduces the chances of an accidental circuit trip.
