The SUNTREE SUP2H-PV should be installed on a 35mm standard DIN rail. When installing the PV-SPD inside an enclosure, a suitable electrical insulator should be used to maintain a minimum 10mm safety distance between the surge protective device and other grounded parts in the housing.
The SUNTREE SUP2H-PV is designed for DC applications with maximum continuous operating voltages of 500VDC, 600VDC, and 800VDC. The appropriate version should be selected according to the operating voltage of the PV or DC system.
The SUP2H-PV is available with maximum discharge current ratings of 20kA and 40kA, based on the applicable product configuration. The discharge current is specified using the 8/20 μs test waveform.
The SUNTREE SUP2H-PV is a 2-pole (2P) DC surge protective device, designed for DC and photovoltaic electrical protection applications.
The protection level depends on the rated operating voltage. The page specifies 2.8kV for 500VDC, 2.8kV for 600VDC, and 3.0kV for 800VDC applications.
