Description
GENERAL INFORMATION
●Varistor photovoltaic surge protective device (PV DC SPD)
●Visual indication and optional remote contact signaling(S) for use in the DC side of PV systems.
●The Prewired complete unit consisting of a base part and replaceable plug-in protection modules.
●In case of insulation faults in the generator circuit, a raliable and tested fault-resistant Y MOV circuit prevents damage to the surge protective devices.
●DIN rail installation.
