Product Description

ZW32-12 Type Outdoor HV Vacuum Circuit Breaker



General Description
ZW32-12 type outdoor high voltage vacuum circuit breaker is three-phase AC,50(60) Hz outdoor power distribution equipment
with the rated voltage of 12kV. It is mainly used to break and close the load current and short circuit current in the electric power system.

It fits to be used to protect and control the circuit in substation, mining and industrial enterprises. It also can be used in the frequently
operation places such as the rural power network. The product is accordance with GB1984-2003 standard.

The ZW32-12G VCB -Isolating switch combination consists of Vacuum circuit breaker body and isolating switch.
