Fuses - 0679L1500-05 Application Field and Working Principle

Fuse is an important safety device in the power system. It can effectively protect circuits from overload and short-circuit current. The 0679L1500-05 is a type of high-voltage fuse designed for low-voltage protection of various electrical and electronic circuits. This article will discuss the application field and working principle of this fuse.

Application Field of 0679L1500-05 Fuse

The 0679L1500-05 is a low-voltage fuse widely used in the electrical and electronic circuits. In particular, it is suitable for the circuits powered by 110-250V AC or dc. It is also used in low-voltage transformers, automotive circuits, aircraft circuits, power supplies, inverters, and communication equipment. It is used to protect these circuits from overload and short-circuit currents.

Working Principle of 0679L1500-05 Fuse

The 0679L1500-05 is a high-voltage fuse, which is designed to protect the circuits from overload and short-circuit current. When the circuit is overloaded or short-circuit current occurs, the fuse’s melting point will reach the established limit. At this point, the fuse will interrupt the circuit, thus alleviating the consequences of the overload or fault current.The 0679L1500-05 fuse is also known as a thermal fuse. This is because it operates on the principle of thermal expansion and contraction. When the circuit is overloaded or short-circuit, the heat generated in the circuit causes the meltable element inside the fuse to expand. This expansion causes the fuse wire to break, thus interrupting the circuit and preventing further damage.The 0679L1500-05 is also a type of dual-element fuse. This means that it has two independent elements, one for sensing the overload current and the other for sensing the short-circuit current. The two elements are connected in series and work together to protect the circuit. The two elements also act as a fail-safe mechanism in case one element fails. This ensures that the circuit is not damaged due to the fault current.

Conclusion

The 0679L1500-05 is a high-voltage fuse designed for low-voltage protection of electrical and electronic circuits. It is most suitable for the circuits powered by 110-250V AC or DC. In the event of an overload or short-circuit current, the thermal expansion of the fuse wire causes it to break, thus interrupting the circuit and protecting it from damage. The 0679L1500-05 fuse is also a dual-element fuse, which provides a fail-safe mechanism in case one element fails.
