ETU5-T2-40PV Series DC Surge Protective Device is designed for enhanced surge protection on the DC side of solar photovoltaic systems. It is suitable for PV string boxes and inverter DC inputs, helping to improve system reliability by limiting the effects of lightning-induced surges and transient overvoltages.
With higher discharge capability for demanding PV applications, the series is well suited for solar installations requiring robust and dependable DC-side protection.
