Lightning protection distribution box for Charging pile
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, powerful discharge capacity of lightning current. It can be used for the general supply of building.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.
