1. High flow capacity, discharge capacity of 25/30kA (10/350μs)
2. Suitable for the first level protection Low limit voltage, good protection effect, no continuous current generation, no impact on the power grid
3. There is no spark in the process of lightning strike, which can be used in a variety of complex environments
4. Built-in thermal tripping protection device, can be disconnected in time, safe and reliable

5. LED status indicator, can directly monitor the performance of internal circuit
6. Small size, easy to install and use



1. Five years of hard work to develop   We spent 5 years working on developing SPD.
2. The failure indication window is electronic    Electronic failure indication window
3. The flow capacity of the traditional structure is 25kA, now it is improved to 30kA(10/350μs).



Design philosophy

The product is a single-phase switching surge protector designed and produced in strict accordance with IEC61643 standards. It passed the Ⅰ test (T1), the flow capacity is large, especially suitable for non-exposed, exposed environment first level lightning overvoltage protection. The protection chip adopts multi-gap cermet protection device to improve the arc discharge voltage. When the lightning overvoltage passes, the peak voltage of the power supply is lower than the arc discharge voltage of the module, it will stop working and extinguish the arc and resume the off state. Therefore, the products using this technology can not only reliably protect the lightning strike and the operating overvoltage of the power system, but also effectively solve the continuous current problem of the switch surge protector, without bringing impact to the power grid.
