Overview
The ZW32ABG-12 outdoor vacuum circuit breaker adopts the vacuum arc-extinguishing principle and a permanent-magnet operating mechanism, integrating microprocessor technology, modern network communication technology and new switchgear manufacturing materials. It is an outdoor distribution device with a rated voltage of 12 kV and 50 Hz three-phase AC. This ZW32ABG-12 outdoor vacuum circuit breaker is widely used in urban distribution networks as a sectionalizing or tie switch, or in rural distribution systems. As an outgoing switch of outdoor substations, the ZW32ABG-12 outdoor vacuum circuit breaker can effectively perform the work of a traditional recloser, breaking and making load current and The ZW32ABG-12 is designed for pole-mounted installation and offers reliable, maintenance-free operation in outdoor distribution networks.
