Cabinet type explosion proof power supply lightning protection boxsmall


Performance Instruction:

Electric surge protector of low-voltage distribution system, which is in the form of a box, is explosion proof and designed according to IEC standard. It has invalidation detection indication, overflowing and overheating protection, and powerful discharge capacity of lightning current. It's applicable to the protection of buildings' general supply system against lightning. 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 (Ninto corresponding connector of the electric surge protector and make sure it's firm and reliableand 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 10m2, short and straight.
