EKU5 Type 2 DC SPD, Imax 40kA, Class II PV Surge Protective Device
Inquire
● Standard: IEC/EN 61643-11
● Surge Rating: Iimp=up to 12.5 kA (10/350 µs), In=up to 30kA (8/20 µs)
● IEC/EN Category: Class I+II / Type 1+2
● Max. continuous operating voltage: from 150V up to 385V AC
● Housing: Pluggable Design
The EKU5-T1+T2-12 is a series of Class I+II Iimp 12.5kA AC Surge Protective Devices designed to protect against indirect and low-intensity direct lightning strikes. These SPDs are equipped with high-energy Metal Oxide Varistors, ensuring low response time and characteristics suitable for both Class I and II protection. The modular design with plug-in inserts allows for easy and quick replacement of function modules in case the MOV reaches the end of its lifespan due to high intensity or frequent overvoltage peaks.
