1P 2P 3P 4P DC SPD Lighting Arrester Surge Protector Device 18 Shield Structure solar PV photovoltaic system

The lightning protection block with the maximum discharge current of 80KA is suitable for the lightning protection of the main power supply in important places. This product is widely used in power systems such as mobile communication base stations, microwave communication bureaus/stations, telecommunications equipment rooms, industrial factories and mines, civil aviation, finance, securities, etc., such as various power distribution stations, power distribution rooms, power distribution cabinets, AC and DC power distribution Screens, switch boxes, and other important equipment that is vulnerable to lightning strikes.
Surge protective device (SPD) is an indispensable device in electronic equipment lightning protection. his
The working principle is that under normal conditions, SPD is in a very high resistance state to ensure the normal operation of the power supply system. When the power supply system gradually increases with the surge current and voltage, the resistance of SPD continues to decrease, the SPD starts immediately within nanoseconds, and the surge energy is discharged to the ground through SPD; After the surge occurs, the surge protector quickly recovers to the high impedance state, so it will not affect the normal power supply of the system.
35mm standard DIN rail installation, 2.5~35mm connecting copper strand ²。
In front of the LHSPD, each pole must be equipped with protection – fuse or miniature circuit breaker lightning current LHSPD protection is used, and short circuit protection is carried out after LHSPD breakdown.
The LHSPD is installed on the front protected line (device) and connected to the power cord.
The first type of product is installed in the building incoming line to accommodate the general distribution box with large surge current.
Class B C products are mostly installed on the floor distribution box.
Class D products are close to front-end equipment, with less surge current and residual voltage
