ZW32-12 Series outdoor high voltage vacuum breaker is produced by Zhejiang Fuladi Power Technology Co., Ltd., used in AC 50Hz ,rated voltage 12kV three-phase power system for closing/breaking load current,overcurrent and short-circuit current.the breaker can equip with reclosing controller to identiy break current characteristics and achieve multiple automatic reclosing or fault isolation.Self-provided PT as a power source,it becomes a smart circuit breake able to controlr with signal output of voltage and current.The electronic PT provides power supply and can complete three-stage composite protection of overcurrent delay, inrush current delay, and short-circuit and quick-break.
Ambient condition:
1. Ambient air temperature:Upper limit of +40ºC,lower limit of -45ºC;
2. Alititude: no more than altitude of 3000 meters(if need higher altitude its rated level accordingly).
3. Wind speed:no more than 34 m/s;
4. Air pollution levels:no more than IV;
