Photovoltaic Solar DC Isolation Switch 4P 1000V 32A
PV Switch-disconnector is suitable for rated voltage DC1200V and below, rated current 32A and below power system. The product can be used for infrequent connection and disconnection, which can isolate the disconnection line and disconnect 1~4 MPPT lines at the same time. It is suitable for isolating lines in DC transmission and distribution systems, such as cutting the direct current circuit between solar panels and inverters.
