0230007.HXSW Application Field and Working Principle

HXSW fuses are ideal for protecting lighting, air conditioning, security systems, and other industrial equipment against short-circuit faults and overload conditions. These fuses feature a time-delay design, which provides a delay before the fuse element opens when subjected to an overload current. This creates enough time for the fuse element to extinguish the arc and pass high frequency inrush currents, while also minimizing false tripping.

HXSW fuses are designed to function as a switches in a circuit. The fuse element warms up to a predetermined temperature when an overload or short-circuit current flows through them. This warming leads to the melting of the fuse element, thereby opening up the circuit. This essentially works as a switch, preventing high current flows from leading to damage to the circuit or the equipment.

HXSW Application Field

HXSW fuses are primarily used in automotive, lighting, air conditioner, security systems and other industrial equipment protection applications. The fuse elements used in these fuses are temperature-sensitive and react to the current that passes through them.

HXSW fuses are also used in residential installations for the protection of electronics and appliances. In this application, the time-delay design of these fuses ensures that the fuse element will not open immediately due to an overload or short circuit current. This time delay allows higher frequency inrush currents to be passed, reducing the risk of false tripping.

HXSW Fuse Working Principle

HXSW fuses are based on a time-delay principle. This means that the fuse element is designed to take some time before it opens when subjected to an overload or short-circuit current. This time delay is done to allow high frequency inrush currents to pass, while also minimizing the risk of false tripping.

The time-delay element of HXSW fuses is built by using a precisely calibrated alloy strip in the fuse element. This alloy strip warms up when a predetermined current flows through it. The current that passes through will cause the fuse element to heat up, thereby melting the alloy strip. This melting process will open the fuse element, breaking the continuity of the circuit.

HXSW fuses are also equipped with a unique feature known as reverse acting time-delay, which allows the fuse to open quicker when subjected to higher overload and short-circuit currents. This protects the circuit from damage due to higher currents.

Conclusion

HXSW fuses are ideal for protecting lighting, air conditioning, security systems, and other industrial equipment against short-circuit faults and overload conditions. Their time-delay design provides a delay before the fuse element opens when subjected to an overload current, thereby creating enough time for the fuse element to extinguish the arc and pass higher frequency inrush currents, while also minimizing false tripping.
