Product Description

General

ZW32-12Y Series outdoor AC vacuum circuit breaker is 12kV distribution equipment of 3 phase,50Hz. According to user requirements, a prepaid circuit breaker's high-voltage metering box can be a three-phase three-wire system(V/V connection) or a three-phase four-wire system(Y/Y connection), and the metering current transformer can be a single ratio or multi ratio. The ratio range is (2.5~1200)/5.
