ZW32-24 outdoor AC high-voltage vacuum circuit breaker (hereinafter
referred to as circuit breaker) is rated voltage of 24kV, 50Hz
three-phase AC outdoor power distribution equipment. It is mainly
used to open and close the load current, overload current and short
circuit current in the power system. Overload current and
short-circuit current. Suitable for substations and industrial and
mining enterprises in the distribution system for protection and
control purposes, more It is suitable for the rural grid and the
place of frequent operation. Structure schematic Product
