ZW32M(T)-12 outdoor high voltage vacuum circuit breaker / primary and secondary fusion (with directional judgment)

Overview

ZW32M(T)-12 outdoor high-voltage AC vacuum circuit breaker adopts the principle of vacuum arc extinguishing, permanent magnet operating mechanism (spring operating mechanism), and integrates micro-processing technology, modern network communication technology and switch manufacturing materials. Outdoor power distribution equipment with a rated voltage of 12kV, 50Hz three-phase AC. This product is widely used in urban power grids as breaking or tie switches, or in rural power distribution systems. Outdoor substation outlet switch can effectively complete the work of traditional recloser, divide and combine load current and short-circuit current.
