General:

ZW32-12 outdoor high-voltage vacuum circuit breaker is used in three-phase power systems with 50HZ and rated voltage of 12kV to break and close load current, overload current and short-circuit current in power systems. The circuit breaker is equipped with a controller to achieve overcurrent tripping, inrush current delay and short-circuit quick-break protection; after configuring the reclosing controller as needed, it can automatically identify the fault type, complete reclosing or locking, quickly isolate the fault and reduce the power outage area; cooperate with the prepayment device or the on-site service terminal for electricity consumption to automatically and remotely manage the circuit breaker; it can also cooperate with FTU to implement line status monitoring, which can meet the needs of various urban distribution network automation. It is widely used in urban power grids as disconnecting and connecting switches, outdoor substations in rural power distribution systems as outgoing line switches or line switches, and places where industrial and mining enterprises' distribution systems and power grids are frequently operated.
