Product Description
ZN63-24 is a series of indoor high-voltage vacuum circuit breakers for three-phase AC power systems with a rated voltage of 24kV and a frequency of 50Hz .
It serves as an indoor switching device for power grid equipment and industrial and mining power equipment, providing protection and control. The circuit breaker is suitable for frequent operations at the rated current or for multiple interruptions of short-circuit currents. It features an
operating mechanism and a dedicated propulsion mechanism, forming a trolley unit for specific applications .
