Kumwell KZ23.PK16.U*DC is single-phase surge arrester class III according to IEC 61643-11 designed for protection of electronic appliances in L.V.supply systems against impulse surge. They are constructed for mounting on DIN rail 35mm for nominal current of 16A. This complex range is produced for nominal voltage within the range of 12, 24, 48, 60 and 110V DC. The right function of KZ23.PK16.U*DC is indicated by green LED diode.
