Fuses

028707.5L is a compact equipment among fuse series. It has high integration, good arc extinguishing performance, strong overload capability and long life. It is mainly used in electronic protection and intelligent control of low-voltage electrical appliances, with reliable performance and high degree of automation.

Application field

The 028707.5L fuse has been widely used in electronic control devices in transformer substations, integrated protection and control devices in energy storage system, transmission and distribution network monitoring, household appliances, firefighting systems, air-conditioning systems, electric heating systems, PV systems, computer communication systems, solar inverters, UPS systems, etc. It also provides reliable protection for the hardware system in these fields against overload and short circuit.

Working principle

The 028707.5L fuse mainly adopts current protection method, uses heat of current for thermal protection and arc extinguishing, and uses the melting of fuse element for overload or short circuit protection. It has the heat resistance performance, current overload performance, short circuit current withstand capability and other mechanical and electrical characteristics for easy selection. The fuse element is made of high-conductivity non-inductive strip with good temperature stability, which can resist damage caused by surge current and make sure that it can work reliably in the environment with current surge or delta wave characteristics.

When the current is within the normal range, the fuse element does not overheat, but when it goes beyond the rating in a short time, the fuse element melts quickly to cut off the circuit and protect the circuit from burning due to overload or short circuit. In the process of melting, the arc is also quickly extinguished by the special arc extinguishing chamber design, ensuring that the fuse element melts quickly and does not cause overfrequency burning.

Conclusion

The 028707.5L fuse is a reliable and automated device for protecting and controlling low-voltage electrical appliances in many industries, with a wide range of applications. It offers superior current overload performance, short circuit current withstand capability and other mechanical and electrical characteristics, and makes use of current heat and melting of the fuse element for protection. This makes the 028707.5L fuse an ideal choice for many applications.
