ZW8-12 outdoor high-voltage vacuum circuit breaker

ZW8-12 electronic PT type outdoor high-voltage vacuum circuit breaker is used in three-phase power systems with AC 50Hz and voltage of 10~12KV. It is used to disconnect and close load current. It has automatic energy storage function, adjustable inrush current control, overcurrent and quick-break protection functions, and can store energy and disconnect and close multiple times under 10KV power failure, realizing local remote control and remote wired control and distribution network automation. It can also be used as a station inlet and outlet line and a power-free scattered point switch outside the station to realize ring network power supply. It is an intelligent switch integrating power protection control and communication.
