The EKU5 T1+T2 DC Surge Protector series is designed for use in photovoltaic (PV) applications of up to 1500V. These Surge Protective Devices (SPDs) comply with the PV T1+T2 classification outlined in the IEC 61643-31 standard. The indication front window helps users to know the status of the device and remote-signal port can provide remote indication and alarm. Additionally, the plug-in module design facilitates later maintenance and replacement.
