Description:SKW1 DW45 series Air Circuit Breaker(hereinafter
referred to as circuit breaker) is applied in distribution network
with AC 50HZ ,rated voltage 690V(or below),and rated current
200A-6300A.It is used to distribute electric energy, protect
circuit and power supply from damage of defaults,such as
overload,under voltage,short circuit,single-phase grounding.Circuit
breaker has intelligent protection function,and its selective
protection is accurate.Besides,it can improve the reliability of
power supply and avoid unnecessary blackout.At the same time ,it
possesses open-type communication interface to realize four-remote
function,namely remote control,remote regulating,remote measurement
and remote communication,in order to meet the requirement of
control center and automatic system.This circuit breaker has
isolation function.Product detail1)rated voltage 660(690)V,rated
current 400-6300A 2)with
telecontrol,teleadjustment,telesignalization and telemetering
interface 3)according to standards: IEC60947-2,GB14048.2
4)controllers H communication/M ordinary intelligent/L economic
type can be available 5)overload for long-time inverse time 6)each
kind of material and specification can be custom-made 7)Protection
Degree:IP30Classify:1. Accord to install:Fix type,Drawer type.2.
Accord to pole:3P,4P3. Accord to operation:Electric
operation,Manual operation(Repair,maintenance)Release:Intelligence
controller,under-voltage instant(or delayed)release,shunt
release.Intelligence controller function:1. intelligence
controller:H(intelligence type),M(Standard type),L(Economy type)2.
Have overload long delayed inverse time limit,short delayed inverse
time limit,constant time-lag and instant function,it can according
to user require to set protect.3. Single ground protect function.4.
Display function:setting current display,action current display and
each line voltage main display(voltage display need ask us when
give me the order)5. Alarm function:overload alarm.6. Self test
function:overheating self test,microcomputer self diagnosis.7. Test
function:intelligent controller of operating characteristic.
Normal use and installation condition:1. Ambient air
temperature:upper limit value not exceeding+40ºC,lower limiting
value not exceeding -5ºC,average value not exceeding +35ºC.Special
orders expected.2. Install address of altitude not exceeding
2000m.3. Atmospheric conditions:Atmosphere relative humidity not
exceeding 50% when ambient air is +40ºC,it can have higher of
relative humidity in the lower temperature ,the average max
relative humidity is 90% in the max wet month,this month average
max temperature is +25ºC at the same time ,it need to think about
condensation of product's surface which will a[[ear with the change
of temperature.It need consult with my company when it exceed
regulated requirements.4. Level of protection:IP30.5. Class of
pollution:3 class.6. Use classes:B classes or A classes.7.
Installation condition:Breaker need according to this instruction
require to install,breaker of vertical gradient not
exceeding5°(mine breaker of vertical gradient not exceeding 15°)/*
