Fuses are an important part of the electronic system. They are widely used in many aspects, such as communications, automobiles, optics, appliances, energy, medical treatment and so on. Fuses have various types, including thermal, magnetic, reed, fast acting, high breaking capacity, semiconductor, cartridge, tube, wire, glass and so on, among which 0299070.ZXT is a kind of fast-acting fuse.

0299070.ZXTF application field and working principle

0299070.ZXT fuses are mainly used in circuits with higher instantaneous over-currents or surges. Its rated current is 0.7A and rated operating voltage is 250V AC/DC. This fast acting fuse has the characteristics of low temperature rise, fast response time, high breaking capacity and good moisture resistance etc. The fuse body is made of PPS material, making it able to be used in super high temperature.

0299070.ZXT fuses use a special contact material and an internal thermal bimetal, which plays a essential role in minimizing the conduction time. The conduction time usually only takes 2S after the rated current passing. The fuse\'s breaking mechanism is based on the bimetal\'s heating and melting, so that contact is opened.

How the 0299070.ZXT fuse works is like this. When the current passing the fuse is lower than its rated current, the contact keep in closed state, while allowing the electric power to be conducted. In case of a short circuit or severe over-current, the current will increase to a certain value that exceeds the rated current. Then the current flows through the bimetal, heating the bimetal until the contact is opened, to achieve the effect of breaking the current off.

Advantages of 0299070.ZXT fuse

0299070.ZXT fast-acting fuse has several advantages, such as small volume, energy saving, low internal impedance, short reaction time and so on. Besides, its high breaking capacity and remote control design help users to locate and measure fault in the device.

In addition, 0299070.ZXT fuse has a safety protection mechanisms, which can be used to prevent the device from overvoltage or overcurrent, in order to reduce the damage of the device and ensure the Stable running of the system. Furthermore, this kind of fuse is very easy to be replaced, which can greatly reduce the maintenance cost.

Conclusion

In summary, 0299070.ZXT fast acting fuse has become ideal choice for the position that requires short time reactions, like Circuit protection, Motor protection and so on. It is characterized by low temperature rise, fast response time, high breaking capacity, good moisture resistance, etc. Although there are numerous types of protection device available, this type of fuse is still widespread due to its advantages over others.
