OUTDOOR HIGH VOLTAGE INTELLIGENT BOUNDARY
VACUUM CIRCUIT BREAKER (WATCHDOG)

Overview
ZW32-24F outdoor high voltage intelligent boundary vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution
equipment with rated voltage of 24kV and 50H three-phase AC. It is mainly used to break and close the load current, overload current and short circuit
current in the power system of the distribution network. It is suitable for protection and control in the distribution system of substations and industrial
and mining enterprises. It is more suitable for rural power grids and places with frequent operations, especially suitable for the needs of urban and rural
power grids.
