ZW32C-12 Outdoor High Voltage Vacuum Circuit Breaker / Deep Integration

Detail

Overview

ZW32C-12 Outdoor High Voltage Vacuum Circuit Breaker / Deeply integrated using the vacuum arc extinguishing principle, permanent magnet operating mechanism (spring operating mechanism), integrating microprocessor technology, modern network communication technology, and new switch manufacturing materials. It is an outdoor distribution device with a rated voltage of 12kV and 50Hz three-phase AC. This product is widely used in urban power grids as a breaking or tie switch, or in rural power distribution systems. As an outgoing switch in outdoor substations, it can effectively perform the functions of traditional reclosers, including making and breaking load current and short-circuit current.
