Porduct Overview

Description

EKU5-T1+T2-7 is a series of Class I+II Iimp 7kA 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.
