Cabinet type power supply lightning protection box（small）

Electric surge protector of low-voltage distribution system, which is in the form of a box, is designed according to IEC standard. It has invalidation detection indication,overflowing and overheating protection, and powerful discharge capacity of lightning current. It's applicable to the protection of buildings' general supply system against lightning. 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.

Section of minimum installed conductor 6mm2 multi-folded wire Protection grade IP20 External dimension 260×180×85mm Sheathing material Metal spraying Mode of connection parallel connection Protection mode 4+0/3+1/1+1/2+0 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 appropriately (recommended earth resistance ≤4Ω). Suggested specification of the lead wire: no less than 6mm2, short and straight.
