Intelligent Framework Air Circuit Breaker 1000A 1250A 1600A,Drawer Type DC/AC Air Circuit Breaker 220V/380V 3P/4Phases 

 

 

Application of Intelligent Air Circuit Breaker(ACB)
DW45 series universal circuit breaker(hereinafter referred to as breaker)is suitable
for the circuit of AC 50Hz with rated voltage 400V, 690V and rated current up to 6300A.
It is mainly used to distribute electric energy and protect circuits and power-supply
equipment from overload, under-voltage, short-circuit and single-phase earthing. with
intelligentized and selective protection functions, the breaker can improve the reliability
of power supply, and avoid unnecessary power failure. The breaker is applicable for
power stations, factories, mines(for 690V) and modern high-buildings, especially for the
distribution system of intelligentized building. This breaker conforms to IEC60947-2 and
GB14048.2. The whole series have past CCC certifi cation.

Feature of Intelligent Air Circuit Breaker(ACB)
1. Rated AC current: 630A-6300A
2. Short-circuit breaking capacity: 80KA-120KA
3. Rated Voltage: under AC690V
4. Two Types: draw-out type and fixed type
5. Equipped with many types of intelligent controllers, of different functions.
6. Both the 3 Pole and 4 Pole air circuit breakers are available.
7. Standards: IEC60947-2, GB14048.2

Categories of Intelligent Air Circuit Breaker(ACB)
1. Our air circuit breaker can be of two installation types: fixed type and draw-out type
2. Number of poles: 3 pole and 4 pole
3. Operation type: manual operation, auto operation
4. Trip types: Intelligent controller, under voltage instant ( or time delay type) trip and shunt trip
5. Intelligent controller categories: L type(basic type), M type( Standard type), and H type ( communication type)

Normal Working Conditions of intelligent Air Circuit Breaker(ACB)
1. The ambient temperature of our intelligent circuit breaker should be within -5°Cto +40°C. The average temperature should not be more than +35°C(except for customized designs)
2. The altitude should be below 2000M.
3. The relative humidity should not be more than 50% at +40°C, the upper temperature limit. At lower temperatures, higher humidity is allowed e.g 90% at 20°C. Dew that is formed during temperature variation should be eliminated, to increase its durability.
4. Pollution garde: class 3
5. The following have an installation grade of IV: main circuit, absent voltage release coil, power transformer primary coil. Other auxiliary circuits and controls have a mounting grade of III.
6. The circuit breaker should be installed according to the manual. The vertival tilt angle should not exceed 5 degrees.
7. if the air circuit breaker is installed in a small compartment of the switch board, the protection grade is up to IP40. If it is then fitted with a door frame, the protection grade is up to IP54.
