KFM is a kind of electrical specialty fuse formed by laminating a new type of compound material into a metal sheet. The KFM can be used to protect the electronic circuit, and can disconnect the circuit in an instant when the current reaches a certain value, so as to avoid greater losses in the circuit due to overcurrent. The KFM has a wide range of applications, mainly used in home appliances, lighting fixtures, electronic control systems and other areas of circuit protection.

In terms of working principle, the KFMs use the heat generated when the current passes through the fuse to melt the material to absorb the energy. When the current in the circuit exceeds the allowable limit, the heat generated by the current will increase and the fuse material will produce a "bridge" effect due to its increased temperature. At this time, the bridge formed by the fuse material will "abnormal" due to its own features, thus breaking the circuit.

In terms of advantages, the KFM has a high breaking capacity and can break current up to 30 times the rated current of the line. It has a small size, which is 1/3 of a slow-action fuse, and is lightweight. In addition, the KFMs have high temperature resistance, they can withstand the working temperature of up to +155° C, and their rated voltage can reach up to 600V. Moreover, the KFM has low resistance characteristics and could meet high-speed, low-loss, high-frequency current explosion protection requirements. Furthermore, it is very stable, and has a long service life.

In conclusion, the KFM is a kind of electrical specialty fuse with versatile applications and a wide working range. It has high breaking capacity, high temperature resistance, small size, light weight and long service life, making it well suited for applications including home appliances, lighting fixtures, and electronic control systems. Its working principle is also very simple, and it is very reliable and durable.
