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.
