PK2 is a single-phase surge arrester type 3 according to EN 61643-11 suitable for TNS and TNC systems. It is designed for universal application for protection of all electrical appliances connected to L.V. supply system against impulse surge effects. It is possible to supply this arrester for different nominal voltage (different from 230 V/50 Hz) on a special demand.
The function failure of varistor is indicated by target disconnection of mechanical thermal fuse which react to varistor overheating above c. 120°C.
Details could be found in the Producer`s catalogue.
