General
Technical Parameter

ZW43- 12(G)/M630- -20 type outdoor high voltage permanent magnet vacuum circuit breaker (Hereinafter called permanent magnet switch) is suitable for the power system with three-phase AC 50 Hz and rated voltage of 12KV. The permanent magnet switch is mainly used as a substation 10KV outlet switch and a line protection switch for closing and opening load current, breaking overload current and short circuit current in 10KV three- -phase AC power system. The circuit breaker complies with GB1984- -2003 "High Voltage AC Circuit Breaker'", DL/T402 -2007 "High Voltage AC Circuit Breaker Ordering Technical Conditions", DL/T403- -2000 "12KV~40.5KV High Voltage Vacuum Circuit Breaker Ordering Technical Conditions" and other technical standards.
