EKU4 Type 2 AC SPD, Imax 40kA, Class II AC Surge Protection Device
Inquire
● Standard: IEC/EN 61643-31
● Surge Rating: Iimp=6.25kA (10/350 µs), Imax=40kA (8/20 µs)
● IEC/EN Category: Class I+II / Type 1+2
● Max. continuous operating voltage (Ucpv): 500, 1000,1500V
● Housing: Pluggable Design
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.
