W1-2000 Series ACB Intelligent Air Circuit Breaker

Normal working and installation condition

◎Ambient air humidity

The upper limit value shall not exceed+40°℃,the lower limit value shall not be lessthan-5°℃,and the 24-hour average value shall not exceed+35℃:

Note:For working condition with lower limit of-10℃or-25℃,the user should declare to ourfactory;

For working condition where the upper limit value exceeds+40°℃ orthe lower limit value is below-10℃or-25°℃,the user should consult with our factory.

◎The altitude of the installation site shall not exceed 2000m

◎Atmospheric  condition

The relative humidity ofthe atmosphere does not exceed50%when the ambient airtemperatureis+40°℃.Atlowertemperature, there can be higher relative humidity.The average maximum relative humidity in the wettest month is 90%,and the average minimum temperature in that month is+25℃,and the condensation on the product surface due to temperature change should  be considered.The usershould consult with ourfactory for condition beyond the regulation.

◎Protection level:IP30

◎Utilization category:Category A or B

◎Installation   category

Forthe circuit breaker and undervoltage release with rated working voltage of 660V(690V)and below,theinstallation category of primary coil of powertransformer is IV;and the installation category of auxiliary and control circuitisII.

◎Installation   condition

The circuit breaker should be installed according to the requirement of this manual,and the verticalinclination of the circuit breakershould not exceed 5°(the inclination of mining circuit breaker should not exceed 15°).

Technical data and performance

◎1.The rated current of the circuit breaker is shownin Table1                                                   Table1

◎2.The rated short-circuit breaking capacity and short-term withstand current of the circuit breaker are shown

in Table2,and the arc distance of the circuit breakeris "zero"(i.e.there is no arc outside the circuit breaker)              Table2

Note:The breaking capacity in the table is the same forthe upperand lowerincoming lines.

◎3.The maximum power consumption of the circuit breakeris 360W.The variation of the rated continuous

current of the circuit breakerunder different ambient temperatures is shownin Table3                    Table3

HW8 series universal circuit breaker(Hereinafter referred to as circuit breaker). rated current 200-1600A, rated working voltage AC 400V、690v. apply to AC 50Hz, It is mainly used for power distribution network. Used for distributing power. Protecting circuit and power supply equipment, be freed from overload, owe voltage, short circuit, the harm of single-phase grounded fault. This circuit breaker has artistic appearance, high breaking capacity, zero flash over. have a variety of intelligent protection function. Can be used as selective protection, action accurate, avoid unnecessary power outages.

enhance the reliability of power supply. This circuit breaker can be widely used in power stations. factories. mines and modern high-rise buildings.
Especially the power distribution system in the intelligent building, In wind power. solar power and other green project also has a wide range of applications.
Product can adopt upper wiring pattern or lower wiring pattern; draw-out type circuit breaker has isolation function.
Conform to the standard: GB14082.2、 IEC60947-2.
Ambient air temperature is-5℃~+40℃, the average temperature in 24h less than+35℃.
Noted: upper limit exceed+40℃ or lower limit below-5'℃ working conditions. the user should be negotiated with the factory.

♦The altitude of the installation site does not exceed 2000m.
♦Atmosphere relative humidity in the ambient air temperature is +40'℃ not exceed 50%: At lower temperature can have higher relative humidity; For example the wettest month average maximum relative humidity is 90%, meanwhile, the month average minimum temperature is 20℃+, Due to temperature change occasionally produce condensation special measures should be taken.
♦Polution levels for level3.

The circuit breaker's Main circuit of installation category is V. When the main circuit of rated working voltage is less than or equal to AC400V. control circuit and auxiliary circuit of installation category except the Undervoltage tripping coil and intelligent controller of power supply transformer primary coil same as circuit breaker. The rest are all ll: When the main circuit of rated voltage is more than AC400V and less than or equal to AC690V. Control circuit and auxiliary circuit need isolation transformer to insulate with primary loop. And the maximum working voltage for control circuit and auxiliary circuit is AC400V. The installation category of control circuit and auxiliary circuit is ll.
