Dehn Surge Arrester
The Dehn DGS275 is a single pole high discharge capacity surge arrestor designed for DIN rail mounting in a consumer switchboard. It meets the international standards recommended by microinverter manufacturers and will provide a reasonable level of protection against grid spikes and surges.
The unit has a replaceable cartridge with a visual status indicator indicating when it needs to be changed.
The installation of an appropriate surge arrester is strongly recommended for all microinverter (and conventional string inverter) installations and failure to install one can affect future warranty claims.
