NH3M315

NH3M315 is a miniaturized fuse which is generally used to ensure safe and reliable operation in low voltage circuit and power distribution system .Because of its small size, high current carrying capacity, high breaking capacity and other characteristics, it is widely used in various electric products, such as home appliances, automobiles, consumer electronics, communications electronics, etc. The working principle and application field of NH3M315 are described in detail below.

Working Principle of NH3M315

NH3M315 is a kind of fuse which works in accordance with the principle of thermal deformation. The fuse consists of an element, a casing, and a support. The element consists of an conductor and a pair of contact members. When the current flows through the element, the temperature rises and the element deforms due to heat resistance. The deformation triggers a switch and disconnects the circuit, thus protecting the circuit from overloading. The connection mode of the fuse is plug-in or snap-in type, which is usually used in enclosed power supply and injection moulded power distribution systems. The element is made of a conductive wire with a certain melting point. When the current reaches a certain level, the wire will melt and break the circuit. The latter will cut off the power circuit to protect it from potential damage.

Application Field of NH3M315

NH3M315 is mainly used in the power supply and distribution systems of household appliances, communication equipment, computers, electronic equipment, automotive electronics and other electrical circuits. The NH3M315 has an excellent temperature coefficient and can be used in varieties of application areas, such as machines, instruments, electrical panels, lighting systems, automatic controllers, telephone boxes, etc. It is highly suitable for electric equipment and instruments with high reliability as the disconnection occurs very quickly.It can be used for protection of primary and secondary circuits with rated operating current up to 63A and rated 8/20usm impulse current up to 500A. The NH3M315 has a higher short time withstand current than normal glass tube fuse, which ensures the maximum protection from power shortage. The NH3M315 can also be used in low voltage circuits, It has a rated voltage of up to 600VAC/ DC, while the rated voltage of a normal low voltage fuses is just 400VAC/DC. This feature makes the NH3M315 the perfect choice for low voltage circuits. In addition, NH3M315 features low cost, compact size, mounting flexibility, plug-in or push-in installation, good welding performance, high connectivity and other advantages. It is easy to install and maintain, which offers great convenience for users.

Conclusion

To sum up, NH3M315, a miniaturized fuse, is widely used in all kinds of electrical equipment due to its superior performance and small size. It is capable of protecting low voltage circuits up to 600VAC/ DC and carries a high current carrying capacity of up to 63A. The NH3M315 is also easy to install and maintain, and features low cost and reliable performance.
