Intelligent MCCB Dam1-250 3p Molded Case Circuit Breaker

Intelligent MCCB Dam1-250 3p Molded Case Circuit BreakerIntroductionCircuit Breakers with Electronic Over Current Release:The feature discriminating electronic circuit breakers from thermal-magneticbreakers is to control the over current releases with electronic is circuit. Electronic iscontrol is performed via microprocessor.During design of the electronic circuit,worst possibilities to encounter in operation have been taken into consideration. In high circuit currents, direct opening has been ensured without operating electronic circuit. In this way, possibility of failure in the electronic circuit has been eliminated.-Maximum, minimum, average etc. Values of the drawn current at various time intervals (day-night) can be taken.Rated and Instant opening current adjustment areas of electronic circuit breakers are quite wide. This feature allows wide use opportunity to the breaker Furthermore, electronic circuit breakers are not affected from ambient temperatures.Advantages°Wide range:125A to 320A(AC)°Compact dimensions°Adjustable thermal setting(40-100%)In.°Adjustable magnetic setting(1.5-12times)In.°Push to trip button provision.°Separate main and arcing contacts°Wide range of accessories.  Electronic Circuit Breakers  ModelDAM1-250Breaking Capacity CodeNSHGRated Current of Frame size- Inm                                                                    (A)250ARated Current-In(40,50 or 55ºC)                                                                      (A)125 - 160(180) -  200(225) - 250 -320ARated İnsulation Voltage -Ui(a.c.) 50-60Hz                                                    (V)750VRated operation Voltage  -Ue(a.c.) 50-60Hz                                                    (V)400/415VNumber of Pole3P Rated ultimate short Circuit breaking Capacity  kA  Icu AC400V/50Hz O-CO          (KA)35506585Rated service short Circuit breaking Capacity  kA  Ics AC400V/50Hz O-CO-CO     (KA)26.2537.548.7551Rated short-circuit breaking capacity Icm(peak)/cos ф AC400V/50HZ O-CO         (KA)77/0.25114/0.25143/0.2178/0.2Rated impulse withstand Voltage -Uimp                                                                            (V)8000Dielectric Propery (V)3000lonization distance                                                                                                              (mm)≤30/0EnduranceTotal Cycles8000Electrical Life1000Mechanical Life7000Over Current tripThermal release adjustable  (0,4-0,5-0,6-0,7-0,8-0,9-1)x1InMagnetic release adjustable  (1,5-2-4-6-8-10-12)xInOperating Curve at 6Ir3S-6S-12S-18SCategory (EN 60947-2/IEC 60947-2)Main circuitA/BAuxiliary circuitAC-15Under Voltage Release √Shunt Release√Auxiliary Contact√Alarm Contact√Auxiliary Contact and Alarm Contact√Handle Operation Mechanism√Electrical Operastion Mechanism √DIN clips-Terminal cover  √Phase seperator  √Extention Handle  √ W (mm)3P1054P-L (mm)3P212.54P-H (mm)3P103.54P-WeightFixed version 3P/4P2.7/3.541.5/5.5Plug-in version 3P/4P3.2/4.24.6/6Draw out version 3P/4P3.6/4.65/6.4Electrical parameters of DAM1 MCCB adjustable type molded case circuit breakerTable1 PR211 typeS.No.FunctionSettingsTypePR211PR211PR211PR211Factroy resetPoles3P3P3P3PRating (A)25040080016001LOverload Current Setting (A)(0.4,0.5,0.6,0.7,0.8,0.9,0.95,1.0)xIn(0.4,0.5,0.6,0.7,0.8,0.9,0.95,1.0)xIn(0.4,0.5,0.6,0.7,0.8,0.9,0.95,1.0)xIn(0.4,0.5,0.6,0.7,0.8,0.9,0.95,1.0)xIn1.0In2Time Delay at Overload Current Setting 3S,6S,12S,18S3S,6S,12S,18S3S,6S,12S,18S3S,6S,12S,18S3S3IInstantaneous Current Setting(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn10InTable2 PR212 typeS.No.FunctionSettingsTypePR212PR212PR212PR212Factroy resetPoles3P3P3P3PRating (A)250400/63080016001LOverload Current Setting (A)(0.4,0.5,0.55,0.6,0.65,0.7,0.75,0.8)xIn(0.4,0.5,0.55,0.6,0.65,0.7,0.75,0.8)xIn(0.4,0.5,0.55,0.6,0.65,0.7,0.75,0.8)xIn(0.4,0.5,0.55,0.6,0.65,0.7,0.75,0.8)xIn1.0In2Time Delay at Overload Current Setting 3S,6S,12S,18S3S,6S,12S,18S3S,6S,12S,18S3S,6S,12S,18S3S3SShort - Circuit Current Setting (A)(1, 2, 3, 4, 6, 8, 10,OFF)xIn(1, 2, 3, 4, 6, 8, 10,OFF)xIn(1, 2, 3, 4, 6, 8, 10,OFF)xIn(1, 2, 3, 4, 6, 8, 10,OFF)xIn6In4Time Delay at Short Circuit Current Setting 0.05,  0.1, 0.25, 0.50.05,  0.1, 0.25, 0.50.05,  0.1, 0.25, 0.50.05,  0.1, 0.25, 0.50.1S5IInstantaneous Current Setting(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn(1.5, 2, 4, 6, 8, 10, 12,OFF)xIn10In6GGround Fault Current Setting (A)(0.2,0.3,0.4, 0.6,0.8,0.9,1.0, OFF)xIn(0.2,0.3,0.4, 0.6,0.8,0.9,1.0, OFF)xIn(0.2,0.3,0.4, 0.6,0.8,0.9,1.0, OFF)xIn(0.2,0.3,0.4, 0.6,0.8,0.9,1.0, OFF)xIn1.0In7Time Delay at Ground Fault Setting 0.1, 0.2, 0.4, 0.80.1, 0.2, 0.4, 0.80.1, 0.2, 0.4, 0.80.1, 0.2, 0.4, 0.80.4S8 Selection of electric or electronic parameters setFunction SET (switch ELT/MAN)9 Used for setting parameters of dip switch of zero lineInN=%In,switch 50/10010 Socket for connection measuring devic
