Product Details:

ZW43(A)-12 11kV 12kV High Voltage Outdoor Vacuum Circuit Breaker

 

General Introduction

ZW43-12 model outdoor AC vacuum circuit breaker is used to make and break load current, overload current and short-circuit current in12kV, 50/60Hz power system. It is applicable for substations, industry and mining, urban and rural electricity power networks, especially applicable in occasions with frequent operation and automatic power distribution network. It accords with the standard of IEC62271-100 & GB1984: AC high voltage cir cuit breaker, IEC60694 & GB/T11022: HV general technical requirement of switch and control apparatus.
