Dw45-6300 3p Acb Intelligent Drawer Type Air Circuit Breaker

Application
1.CJW1 series intelligent universal circuit breakers could be used fir controlling the low voltage distribution net and keeping it safety. Installing in the
   low voltage distribution panels, it works as master switch to play general safety role. lts technical nature has reached the international advanced
   standard of that kind of products in 1990s. It suits the circuit of AC 50Hz, rated volage is 660V (690V) or below, rated current 400A-6300A.
2.Varied intelligent controller offers various functions. 
3.The breakers comply with the demands of the following standards, IEC 60947-2,GB14048.2-2001.

Classification
1.According to the mounting: fixed and draw-out
2.According to the poles: three poles, four poles
3.According to the operation ways: motor and manual (maintenance and repair)
4.According to the release: inteligent over current controller,under-voltage instantaneous (or delay) release,and shunt release
5.The capability of the intelligent over-current controller:
   a) classification: H type (normal), M type (normal intelligent), L type (economic)
   b) has the function of overload long delay reverse time limit protection
   c) single phase earthed protective function
   d) indication function: setting current indication, action current indication, each wire voltage indication(should mention as you order).
   e)Alarm function
   f) Self- diagnostics function
   g)Test function

Environment condition for operation and installation
1.Ambient temperature: -5ºC ~ 40ºC, and average temperature in 24 hours below +35ºC (except for special orders).
2.Elevation of installation site: ≤2000m
3.Relative humidity: Not exceeding 50% at he maximum ambient temperature of +40ºC. With lower temperature, higher humidity would be permitted,
   but the lowest average temperaure in a montn not exceeding +25ºC during the most moist month, and the maximum monthly average relative
   numiaty not exceeding 90% in that month, and giving consideration to the dews on the goods surface, which would appear due to temperature
   change.
4.Pollution protection: 3 degree.
5.Installing categories: IV for breaker's main circuits, coils of under voltage release and primary circuit of transformers; III for other auxiliary circuits
   and control circuit.
6.The breakers used in ships and in humid tropical area can work normally without influence of humid air,salt fog and mildew.
7.The breakers used in ships can operate reliably under normal vibration.
8.The breaker should be installed according to stipulations in operation manual. For breakers in common use, the vertical gradient is not more than
   50, for that used on ships, the vertical gradient is not morethan 22.50.
9.The breaker should be put in the place where there is not any explosive medium and conductive dustand no gas, which would corrode metal or
    destroy the insulation.
10.The breaker should be installed in compartment of switchboard and doorframe should be fixed additionally,protection grade is up to lP40.
