Ex9UE surge arresters are designed to protect against surges caused by transient fast switching operations or indirect lightning surges. It is recommended to install the devices every 10 - 20 m of cable length, in main switchboards as well as sub-distribution boards.
The design of Ex9UE2 arresters is based on varistor elements. It provides low response time. Built-in auxiliary contact allows for electrical signaling of the status of the insert.
Modular design with interchangeable inserts allows quick and easy replacement of functional modules in case they burn out, due to the frequent occurrence of surge peaks. They are tested in accordance with EN 61643-11.
