- Protect electrical appliances (800V Photovoltaic accessories)
- DC surge protective device, protect against lightning surge voltages in solar system (PV 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), ely if the line routing is external and long High energy Movs equpped with specific thermal disconnectors and related failure indicators .
This AC Surge Arrester – Type 1 – 3 Phase combined lightning current and surge arrester is for three phase systems. This 4 rail mounted type 1 and 2 combined lightning and surge arrester is for grid AC connections. It is to be used when the installation has a fitted lightning protection system. It will need to be fitted at the origin of the supply with type 2 SPD closer to the inverter.
