Product DescriptionZN12 series of indoor high voltage vacuum
circuit breaker is with rated voltage of 40.5kV,three-three phase
A.C.50(60) Hz indoor high voltage switch equipment.The structure of
this kind of circuit breaker is simple but with strong breaking
capability;it is suitable for application in the mining
industry,substations and power transmission and distribution
systems for controlling and protecting the switch.Especially
suitable foe the industry which requires frequently operations like
metallurgy fields,electric arc steel plant to control and protect
the equipment.This kind of vacuum circuit breaker can be assembled
with truck which can be suitable for many kinds of switchgear such
as JYN1,GBC etcModel DescriptionProduct technical parameters and
external dimensionsProduct structure features 1.The operating
mechanism is introduced the technique of operating mechanism from
Siemens 3AF vacuum circuit breaker,the operating mechanism is
integrated with vacuum circuit breaker,with characteristics of
short transmission routes,less chains and high transmission
efficiency.2.This operating mechanism adopts spring type,it can be
operated by AC or DC,also can be operated by manual.Environment
condition1. Ambient air temperature: -5~+40 and the average
temperature should not exceed +35 in 24h.2. Install and use
indoors. Altitude above sea level for operation site should not
exceed 2000M.3. Relative humidity should not exceed 50% at max
temperature +40. Higher relative humidity is allowed at lower
temperature. Ex. 90% at +20. But in view of the temperature change,
it is possible that moderate dews will produce casually.4.
Installation gradient not exceed 5.5. Install in the places without
fierce vibration and shock and the sites insufficient to erode the
electrical components.6. Any specific requirement, consult with
manufactory.Product detailsProducts real shotA corner of the
