EKU6-T2-40S is a group of Type 2, Class C Surge Protective Devices with a modular design featuring plug-in modules. These devices are designed to protect against transient overvoltage caused by fast switching operations or indirect lightning strikes (residual effects). They are multi-pole compact surge protectors that allow for easy installation and retrofitting due to their narrow design, requiring minimal space (width of 18mm).
