High Voltage Surge Arresters AC 4-44kV - ABB MWK

ABB Power ProductsABB Medium Voltage MV Surge Arresters

ABB MWD High Voltage AC Surge Arresters

Indoor / Outdoor 4kV-44kV 


ABB MWK indoor and outdoor high voltage AC surge arresters protect against multiple atmospheric and switching overvoltages including Very Fast Transients (VFT). ABB MWK surge arresters are suitable for the protection of high voltage transformers, cables, motors and other HV  electrical equipment. ABB MWK surge arresters cover the complete range of continuous operating voltages from 4-44kV(kV rms), including 6.6kV, 11kV, 15kV, 20kV, 24kV, 33kV, 36kV cable networks and systems. Designed and tested according to IEC 60099-4 and fulfills the requirement of ANSI/IEEE C62.11.
