Product description

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.

This product accourding to IEC66143-1/EN61643-11.
