Power supply lightning protection module（type A）

Electric surge protector of low-voltage distribution system is design according to IEC standard.It has invalidation detection indication,standard modularization installation,changeable lightning protection module and powerful discharge capacity of lightning current.It’s appliable to the protection of buildings’ general supply system against lightning.With 35mm standard guide-way,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.

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.
