Non-serial-data fuses (NSD4) are a relatively new form of electrical specialty fuse. They offer superior protection from short-circuiting, as well as protection from current surges within circuits. This type of fuse is available in a wide variety of ratings, from around two amperes up to hundreds, depending upon the incorporation into the circuit design. The operating temperature range for these fuses is generally between -40 Celcius to +125 Celcius.

NSD4 fuses employ a fast-operating, very reliable thermal-magnetic principle of protection. This fuse design is most often used in residential or commercial buildings to protect electrical systems and equipment from short circuits, overloads, and high-intensity current surges that could potentially damage systems and equipment. The fuse is fast-acting, which limits the amount of current that can flow through it within a short period, therefore it will help reduce the damage to a circuit, or system, caused by such a surge or short circuit.

The fuse operates by the action of the thermal-magnetic principle. This means that when either the current strength reaches a predetermined level threshold, or the temperature rises to a predetermined level, the fuse will “blow” or open the circuit. This action will prevent any further current from passing through the circuit, and will also act to prevent any further overloads or surges from affecting the system. A further benefit to this type of fuse is the fact that it will reset after the overload or surge has passed.

One of the most common application fields for NSD4 fuses is in the protection of air conditioning systems. These systems typically have a large motor, and use a significant amount of power. The use of a thermal-magnetic fuse in this application helps to protect the system and its components from an overload or short circuit. Additionally, NSD4 fuses can be used in applications such as outdoor lighting systems, appliances, and commercial bypass switches, as they offer enhanced protection from sudden increases in current.

Another key field for NSD4 fuse usage is in the protection of telecommunications systems. When combined with an appropriately-sized fuse, these fuses are able to effectively protect data and communications systems from damage caused by surges, or direct contact with hazardous power sources. This type of fuse can also help to ensure that data and communications systems remain operational even in the event of unstable power supply, and will protect any components and wiring from any associated current overloads.

In summary, the use of NSD4 fuses in electrical systems offers enhanced protection from overloads and surges, while at the same time providing a reset feature that allows the system to operate normally after the surge or overload has passed. This type of fuse is most often used in the protection of air conditioning systems as well as telecommunications systems, and it is also able to offer enhanced protection from direct contact with hazardous power sources. Additionally, the wide variety of ratings, temperature ranges, and operating principles make NSD4 fuses an ideal option for a variety of applications.
