NSPV surge protective device AC Surge protection device(SPD) is an indispensable device for lightning protection of electronic equipment. It is used to limit the instantaneous overvoltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or A powerful lightning current drains into the ground to protect the protected equipment or system from impact and damage.

● The junction box uses the PPE/PA,High rigidity, high temperature resistance chemical resistance, wear resistance and pollution resistance ● The junction box uses the glue to seal, the waterproof effect is better, the fitting interior heat is better. ● This junction box is a three-part design, and the cable adopts horizontal outlet mode, which can reduce the cable bending stress, save the cable usage, reduce the power loss of PV module, and divide the influence of "hot spot effect" into three parts. The influence of high temperature on photovoltaic modules is reduced. ● The diode and the terminal adopt an integrated packaging mode, and the terminal uses red copper

NSPV surge protective device DC SPD protect against lightning surge voltages in solar system (photovoltaic power supply system). These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.High energy MOVs equipped with specific thermal disconnectors and related failure indicators.
