Power supply lightning protection module（B+C type）

Electric surge protector of composite low-voltage distribution system is designed according to IEC standard. It adopts the most advanced technology of pre-ignition clearance and automatic matching of energy and has invalidation detection indication, standard modularization installation, and powerful discharge capacity of lightning current. It's applicable 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.

Installation Method:

Ground the null line repeatedly when long-distance overhead incoming feeder is connected to the building.
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.
