Photovoltaïc installation surge arrester DPVN1 series

DC powerMOVDIN rail

Overview
The DPVN1 series by CITEL is a range of Type 1+2+3 surge protective devices specifically designed for photovoltaic installations. Based on CITEL's patented CTC technology, the DPVN1 integrates a thermosensitive separation point at the core of the SPD to ensure the safest disconnection available. Devices are DIN-rail mountable, compact and fitted with a visual failure indicator for straightforward installation and maintenance.
