ZW32 Outdoor Permanent Magnet High Voltage Ac Vacuum Circuit Breaker

Overview

ZW32ABG-12 outdoor high-voltage permanent magnet vacuum circuit breaker (hereinafter referred to as permanent magnet switch) is an outdoor high-voltage switchgear with three-phase AC 50Hz and rated voltage of 12kV. The permanent magnet switch is mainly used as a 10kV outgoing switch in a substation and a 10kV three-phase AC power system as a line protection switch for splitting and combining load current, breaking overload current and short-circuit current.
The circuit breaker conforms to the technical standards such as GB1984-2003 “High Voltage AC Circuit Breaker”, DL/T402-2007 “High Voltage AC Circuit Breaker Ordering Technical Conditions” and DL/T403-2000 “12kV-40.5 High Voltage Vacuum Circuit Breaker Ordering Technical Conditions”.

Normal Use Conditions
