NOARK 2P AC 20 kA 1F surge arrester 


This line of surge arresters is made up of class 2 devices. They are designed to protect against overvoltages caused by transient, fast switching operations or indirect lightning strikes.

It is recommended to install the devices at every 10–20 m of cable length, in main boards and switching substations. Ex9UE2 20 440 devices are designed to coordinate with class 1 of the Ex9UE1 35 line, in the case of Ex9UE2 20 275, the coordination with Ex9UE1 35 is done with a 10 m cable.

The design of Ex9UE2 arresters is based on varistor elements. It provides a low response time. The modular design with replaceable inserts allows for quick and easy replacement of functional modules in case of burnout, due to the frequent occurrence of surge peaks.
