Product Description:

ZW8-12 electronic PT type outdoor high-voltage vacuum circuit breaker is used in the three-phase power system with AC 50Hz and voltage 10~12kV. It is used for segmenting and closing load current. Control, over-current and quick-break protection functions, can store energy and switch on and off multiple times in the case of 10kV power failure, realize local remote control and remote wired control and distribution network automation. It can also be used as a scattered point switch for incoming and outgoing lines in the station and non-power supply outside the station to realize ring network power supply. It is a functional switch integrating power protection control and communication.
