Backup through-flow capacity power supply surge protector


Electric surge protector of backup protection low-voltage distribution system, which is in the form of a box, is designed according to IEC standard. The use of advanced backup flow capacity technology and MOV matrix power supply lightning protection technology can cooperate with each other to provide suppression of higher harmonics when the main discharge channel of the lightning arrester works normally, and cooperates with the main discharge channel to effectively reduce the residual voltage.It has the function of invalidation detection indication. With large discharge capacity of lightning current and low residual voltage, it's applicable to the surge protection of buildings' power system. This lightning arrester is very convenient to be maintained. It connects with the circuit in parallel and has no limit to the power of equipment fixed later. It has been registered as the patent product of Haide Lightning Protection Corporation.

Installation method：


Ground the null line repeatedly when Long-distance overhead incoming lines enter buildings.

Plug the power phase line (L) and null line (N）into corresponding connector of the electric surge protector and make sure it's firm and reliable. Connect the ground terminal of arrester with the ground lead of lightning protection well (recommended earth resistance ≤4Ω).

Suggested specification of the lead wire: no less than 6mm2, short and straight.
