Product Description
ZW32-12 series owtdoor high-volage vacuum circuit breakers (hereinafitr referred to as " circuit breakers " are outdoor distribution swithgear with ratedvoltage of 12k V and three-phase AC of 50Hz.Cireuit breaker is mainmly used for opening and closing Load current, overload curent and short-eircuit currentin power lines have overload and short-circuit protection functions, meet the requirements of control and measurement. and can alsorealize remote controland monitoring functions, which are widely used in l is used for control and operation in distributio systems of substations and industrial and miningenterprises.and is especially suitable for places requiring frequcnt opcration.
Cireuit breakers meet technical standards such asGB1984-2003,DL/T402-2007 and IEC60056.
