Kumwell KZ23.P3K.*.ds is a three-phase surge arrester type 3 according to EN 61643-11 and Class III according to IEC 61643-11 suitable for use in TNS, TNC and TT systems.

These are parallel devices intended for protection of electronic appliances against impulse surge. All varistors in KZ23.P3K device are titted with thermal fuses to prevent short and also permanent overloading.

The function failure of KZ23.P3K.UN230.ds and KZ23.P3K.UN400.ds devices is indicated by target disconnection of mechanical thermal fuses which react to varistors overheating above c. 120°c. If one of the three thermal fuses reacts, the non-potential contact FAILURE disconnects at the same time.
