NOARK Scaricatore di sovratensione 4P Tipo C 2 275V
Surge arresters Ex9UE are designed to protect against overvoltages caused by unsteady fast switching operations or indirect lightning surges.
It is recommended to install the devices at a distance of every 10 - 20 m of the cable length, in main boards and sub-distribution boards.
Tested according to EN standard 61643-11.
The design of the Ex9UE2 limiters is based on varistor elements.Provides low response time.
The built-in auxiliary contact allows for electrical signaling of the insert status.
The modular, insert-replaceable design allows for quick and easy replacement of functional modules if they burn out due to frequent surge peaks.
