Ex9IR50 DC Rotary Switch Disconnector is an electrical safety device that manually disconnects itself from applications in such as Photovoltaic and energy storage systems. In PV applications this disconnector is used for manually isolate solar panels for maintenance, installation or repair purposes. Utilization category is DC-PV2, that means connecting and disconnecting PV circuits where signifi cant over-currents may prevail and where current fl ow can be in both directions; for example, where several strings are connected in parallel and to the same inverter, or, one or more strings with a battery. Rated current is up to 50A for 1100V DC and 26A for 1500V DC in solutions from 2 layers up to 8 layers.
