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, lightning stroke numbering display,installed overflowing and overheating protection with
great lightning current discharge capability. It's applicable to the
protection of buildings' general supply system against lightning, as
well as Grade 1 and 2 lightning protection of the general supply in
building, machine room, plant and enterprise to make sure the safe
operation of electronic equipment and other electrical 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.
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.
