Product description:
ZW32-12 series outdoor AC high-voltage vacuum circuit breaker is a three-phase AC 50 Hz outdoor high-voltage switchgear, applicable to three-phase power system with rated voltage of 12kV, for making/breaking load current, overcurrent and short-circuit current. The circuit breaker can be configured with a reclosing controller to identify the breaking current characteristics and realize multiple automatic reclosing or fault quarantine. With PT (voltage transformer) as power supply, it can become an intelligent circuit breaker with voltage and current signal output control function. Electronic PT power supply and can complete three sections of overcurrent delay, inrush current delay, short circuit and quick-break differential composite protection.
Normal service conditions:
1. The altitude does not exceed 2000 meters.
2.Ambient air temperature: maximum + 40 ° C, minimum -40 ° C in general area; minimum -40 ° C in Paramo area.
3. Installation site: free of fire, explosion hazard, pollution, chemical corrosion and frequent violent vibration.
Special service conditions: if the circuit breaker is required to operate in an environment beyond the above normal service conditions, the user shall consult with the manufacturer and put forward specific requirements, which can be implemented after both parties reach an agreement.
