B+C composite power supply lightning protection box

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 the connected device.
