Product Description

Product Description

General
The rated insulation voltage of YCM8YV series electronic liquid crystal molded case circuit breakeris 1000V. It is suitable for the distribution network with AC 50Hz, rated voltage of 400V and below and rated current up to 800A. Under normal circumstances, the  circuit  breaker  can  be  used  for  infrequent  switching  of circuits  and  infrequent starting of motors. It can protect the circuits from overload and short circuit, as well as
over-voltage, under-voltage and phase loss. Standards:IEC60947-2
Operating Conditions
1. The ambient temperature is -5ºC~+40ºC, and the altitude is no more than 2,000m.
2.Atmospheric conditions: the max. temperature is 40ºC, and the relative humidity of air is not more than 50%; higher relative humidity can be allowed at lower
temperature like 90% at 20ºC . Special measures shall betaken for occasional condensation due to temperature change.
3. The external magnetic field of the installation site shall not exceed 5 times of the
geomagnetic field in any direction, avoid large electromagneticinterference (such as  high-power motor or frequency converter) near the product, explosive and corrosive gas, as well as invasion by rain and snow, and keep the place dry and ventilated.
4. Class of pollution: Class 3; installation category: III.
Features
1. Environmental protection, Wide range of application
2. Easy to operate,Maintenance-free, High security
3. Clearly visible real isolation break
4. Single cabinet structure, field-configurable, and expandable as desired
5. Replace SF6 load switch ring main unit
