1769-PB41769-PB41769-PB4结构图中触点2有三对，串联在被保护的三相主电路中。手动扳动按钮为“合”位置（图中未画出），这时触点2由锁键3保持在闭合状态，锁键3由搭钩4支持着。要使开关分断时，扳动按钮为“分”位置（图中未画出），搭钩4被杠杆7顶开（搭钩可绕轴5转动），触点2就被弹簧1拉开，电路分断。自动开关的自动分断，是由电磁脱扣器6、欠压脱扣器11和热脱扣器12使搭钩4被杠杆7顶开而完成的。电磁脱扣器6的线圈和主电路串联，当线路工作正常时，所产生的电磁吸力不能将衔铁8吸合，只有当电路发生短路或产生很大的过电流时，电磁吸力才能将衔铁8吸合,撞击杠杆7，顶开搭钩4，使触点2断开，从而将电路分断。欠压脱扣器11的线圈并联在主电路上，当线路电压正常时，欠压脱扣器产生的电磁吸力能够克服弹簧9的拉力而将衔铁10吸合，如果线路电压降到某一值以下，电磁吸力小于弹簧9的拉力，衔铁10被弹簧9拉开，衔铁撞击杠杆7使搭钩顶开，则触点2分断电路。当线路发生过载时，过载电流通过热脱扣器的发热元件13而使双金属片12受热弯曲，于是撞杆7顶开搭钩，使触点断开，从而起到过载保护作用。根据不同的用途，自动开关可配备不同的脱扣器。备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！————————————————————————————————AEGModiconPC-E984-255,CpuModule24vdc-PCE984255Tech-motivetool49-4100-01C5,ToolControlModule,REVTech-motivetool49-4100-01C5,ToolControlModule,REVAEGMM-PM22400CPN:92-01203-01.TestedABB3HAB4249-1/07RobotFlexableCableHarnessABB3HAB4248-1/6RobotFlexableCableHarnessBrotherB52J026-1PCBBoard,9204026BoschRexroth0608830160TighteningController,5V-1ModiconAS-P484-600,PowerSupply,MissingKey,RefurbiFanucA16B-2200-0141/09DBase2withSubCPUSICKPLS101-312PhotoElectricLaserScanner.UnithasbTechMotiveT066I020SSP3ElectricFasteningToolAllenBradleyACServoMotor1326AB-A3G-11-A4SchneiderTSXCCY11281Ch.ElectronicCamModule.AEGM327-T70A-YY01-1U,GettysPermanentMagneticServoSiemens6SN1227-2ED10-0HA0SimodriveFMStepdrive-6SNHeidenhainLS40389cmLinearScale,RefurbishedAllenBradley20AD8P0A3AYNNRNNPowerFlex70UnitModiconM462-GAS0-0N0C,PN:S62G-A00-P0V0,SevroMotorRModiconCyberline1000DServoDriveDR-D020-001Siemens1FK7040-5AK71-1EG0,3~BrushlessServoMotor-StiMiniSafeMS4300SafetyCurtainTran***itterMS4356BXSiemens1FK7080-5AF71-1EH0ServoMotor-StiMiniSafeMS4300LightCurtainReceiver56"MS4356TRKollmorgen/IndustrialDrivesBDS4-206J-204B2AmplifierIndramatDKC04.3-040-7-FW,279771ServoDrive,DKC04304BergerLahrTwinLineServoDrive-TLC512PSFCTCModel2600AutomationController-2600XM-10TelemecaniqueATV66U72N4,ACDrivePhoenixContactDV-OPC5515-016-BC/A.00,Rev585A.BC.00PKS-DIGIPLAN1073-808DigiDrive1073CB/204/1TypeCBPKS-DIGIPLAN1073-800DigiDrive1073-1073CA/208/CH+FCompumotorSR1015B62DYNASERVDDServoActuatorModiconAS-52P-111,RevA5MemoryBoardModiconAS-521P-011,RevC35,PCB&PromAssy,IOPBoarAtlasCopcoQMR62-32-RT&QRT62200&4230175080RexrothMKD041B-144-KG0-KN3-PhasePermanentMagnetMotYaskawaACServoMotorUTMAH-B15BSB,Type:USAMED-03MS1RexrothMKD041B-144-KG1-KNPermanentMagnetMotorPN:RSquareDI-LineBusswayUnitPQ3620GRA-SEWMDV60A0055-5A3-4-00EurodriveMovidrive8.7kVAIndramatMAC112C-0-ED-3-C/130-B-1MotorFanucA06B-0128-B675#7008,ServoMotor,ReconditionedSiemens6SE9210-7CA40MicroMasterDriveInput230vac-1.CiscoWS-C2955S-12CatalystSwitch-BoschLTE45-2.5KVA,ServoAmplifier-BergerLahrTwinLineServoDrive-TLC511PSFMitsubishiMR-S11-103-E01CNCServoDrive,MainBoardRMitsubishiMR-S11-300-E01CNCServoDriveMainBoardRSiemens6ES7156-0AA01-0XA0DP/ASInterfaceLink,6ES71ModcionPremiumTSXETY4103,TSX5710/1000TCP/IPModuleAllenBradley1386-AA15ServoAmplifierinsealedanti-Horyu4019-100DCNCBoardAllenBradley1391-DES22-DIACServoControllerABBDSQC335,3HAB6182-1,CPUUnitABBDSQC335,3HAB6181-1,CPUUnitModiconDR-D010-001,Cyberline1000DServoDrivePN:AS-SquareD1400570-004PowerModule4809v1300a,14005700BergerLahrVRDM31122/50LWCServo/StepperMotorIGFanucA06B-6058-H331ServoAmplifierTripleAxisA06B6Tech-motivetool49-4100-03C5ToolControlModuleExlarGS30-0302-0EA-LV-KM1LinearServoActuatorXycom4800-E1,PN:90441-001TerminalExpansionModuleFanucPCUBoard-A16B-3200-0040/05DModiconAS-521P-002,RevC8,IOPControllerBoard.SellModiconAS-506P-008,ASSYM506-000RevC,MemoryBoardFanucA06B-6079-H106ServoAmplifier-A06B6079H106-RParkElectricCo.PBP6455BuswaySystemBusPlugFanucA06B-6079-H104ServoAmplifierModule-A06B6079HCincinnatiMilacron3-700-0146APowerSupplyDVTFL24BK-BDIO8/8HDDSUB,PN:CON-EBC,EthernetI/OFanucA06B-0512-***1#0008Model5ACServoMotor-ParkerDigiplanBLX75BrushlessServoDriveFanucIC660ELB922MDualChannelPCIMModule(UnopenedBAutotechSAC-M1451-0ABProgrammableLimitSwitchWithIAutotechSAC-M1450-LT0ProgrammableLimitSwitchWithCRobotron503-7-0324-01Series400CascadeModuleAllenBradley1326AB-A3E-11-ACServoMotorHofman/McLeanM33-0426-G009HElectronicEnclosureAirCAllenBradley440L-R4K1120YD/AGua***hieldReceiverSerSICKFGSS1350-11LightCurtainSenderFECAXIS103AAFC1100AxisController,Type103ComprehensiveCVC-RGBHV/HR1000ft,PremiumHighResoluBelden89729,2pr24awgstranded(7x32)TCconductors,GrayhillMicroDAC72-MDC-32ADCDataAcquisitionandCoYamazakiMV4-200WIndexTableDrivewithBoardZTU-DRIVParkerCTCPA10T-133IndustrialComputerw/TouchscreenTelemecaniqueXUSLTQ6B0260SafetyLightScreenSet-NERexrothConnectingCable0608750103-PD14APowerSupplyACGeneralElectric193X256AAG01AmplifierCardBoschRexroth0608830162,KE300CommunicationUnit,AB1389-AA045-A01Bulletin1389ServoAmplifierCincinnatiMilacron3-700-0135APowerSupplyKollmorgenB-204-B-39-016ServoMotorFanucIC660ELB922MDualChannelPCIMModule(OpenBox))
