Product Overview
The ZW20-12 outdoor high-voltage AC vacuum circuit breaker is an outdoor
power distribution device rated at 12 kV and designed for three-phase AC 50
Hz systems. It is primarily used to interrupt and close load currents, overload
currents and short-circuit currents in power systems. It is suitable for use in
substations and the power distribution systems of industrial and mining
enterprises for protection and control purposes, and is particularly well-suited
for rural power grids and locations requiring frequent operation. When used in
conjunction with a controller, this product meets the requirements of
distribution automation systems and can reliably and effectively perform the
functions of a traditional recloser.
