High Quality Surge Protector 4 Pole SPD 20kA Lightning Protection Solar Surge Protection Device Protector
Products Description
Surge Arrester Application
NLDS1 Surge protective device, 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.
Surge Arrester Features:
1. Indicator window is obvious (green is OK, red indicates failure)
2. Fully enclosed terminal
3. The shell is made of PC flame retardant material, fire insulation
4. Replaceable module
