B+C composite power supply lightning protection box
Electric
surge protector of composite low-voltage distribution system, which is
in the form of a box, is designed according to IEC standard. It adopts
the most advanced technology of preignition clearance and automatic
matching of energy and has validation detection indication, overflowing
and overheating protection, lightning stroke numbering display and
powerful discharge capacity of lightning current. It can be used in
Grade B and C lightning protection for the general supply of building,
machine room, plant and enterprise to make sure the safe operation of
electronic equipment and other utilization equipment. 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 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.
