ZW32 Series Medii voltage circa ruptor

Overview
Suspendisse Products

The ZW32-12 outdoor high-voltage vacuum circuit breaker is an outdoor power distribution switching device with rated voltages of 12kV, 24kV, 40.5kV and a three-phase alternating current of 50Hz or 60Hz.

The circuit breaker is mainly used for breaking and closing the load current, overload current,and shor-circuit current in the power line.

It has the functions of overload and short-circuit protection.

It meets the requirements of control and measurement.

It can also realize the functions of remote control and monitoring.

It is widely applied in the power distribution systems of substations, industrial and mining enterprises for control and operation purposes.

It is especially suitable for places where frequent operations are required.
