产品原理分析断路器与接触器区别断路器（英文名称：circuit-breaker，circuitbreaker）是指能够关合、承载和开断正常回路条件下的电流并能关合、在规定的时间内承载和开断异常回路条件下的电流的开关装置。断路器按其使用范围分为高压断路器与低压断路器，高低压界线划分比较模糊，一般将3kV以上的称为高压电器。断路器可用来分配电能，不频繁地启动异步电动机，对电源线路及电动机等实行保护，当它们发生严重的过载或者短路及欠压等故障时能自动切断电路，其功能相当于熔断器式开关与过欠热继电器等的组合。而且在分断故障电流后一般不需要变更零部件。目前，已获得了广泛的应用。电的产生、输送、使用中，配电是一个极其重要的环节。配电系统包括变压器和各种高低压电器设备，低压断路器则是一种使用量大面广的电器。http:///Home/News/data_detail/id/ml接触器分为交流接触器（电压AC）和直流接触器（电压DC），它应用于电力、配电与用电。接触器广义上是指工业电中利用线圈流过电***生磁场，使触头闭合，以达到控制负载的电器。AllenBradleyPanelView5502711-B5A2XSerBModuleALLENBRADLEY2711-T5A15L1PANELVIEW550"NOB"TOUCHAllenBradley2711-K5A2/H|PanelView550AllenBradley2711-B5A5/B|PanelView550AllenBradleyPanelView5502711-K5A2AllenBradley2711-T5A20L1Panelview550ALLENBRADLEYPANELVIEW5502711-K5A1AllenBradley2711-B5A1L1/F|PanelView550AllenBradley2711-B5A20L1/HPanelview5502711B5A20L1AllenBradley2711-K5A1/H|PanelView550AllenBradleyPanelview5502711-K5A5SerFRevJUsedAllenBradley2711-B5A2/H|PanelView550ALLENBRADLEYPANELVIEW550MAINBOARDTOUCHSCREENAllenBradley2711-T5A8L1|PanelView550AllenBradleyPanelView5502711-B5A2SerBModuleAllenBradley2711-T5A2L1|PanelView550AllenBradley2711-B5A2/E|PanelView550AllenBradleyPanelView5502711-B5A1USEDAllenBradleyPanelView550GoodAsSealed.BNIBAllenBradleyPanelView5502711B5A5NEWAllen-BradleyPanelView550W/Keypad2711-B5A8NICEAllenBradleyPanelView550,2711-B5A1,GoodConditionRemoteI/OCommunicationandRS-232PrinterPortAllenBradley2711-B5A8/F|PanelView550AllenBradley2711-B5A8/F|PanelView550Allen-Bradleypanelview550model2711-B5A2AllenBradley2711-K5A5/C|PanelView550AllenBradley2711-K5A5/B|PanelView550AllenBradley2711-B5A2/H|PanelView550AllenBradleyPanelView5502711-K5A2SERFModuleAllenBradley2711-K5A10/H|PanelView550AllenBradley2711-B5A3/G|PanelView550ALLENBRADLEYPANELVIEW550REPAIRPART77131-103-01AllenBradley2711-K5A8/E|PanelView550*REM*AllenBradley2711-B5A2/G|PanelView550NIBALLENBRADLEYPANELVIEW550KEYPAD#2711-B5A1AllenBradley2711-K5A5/BPanelview5502711K5A5/BAllenBradley2711-B5A1/C|PanelView550EK-503ALLENBRADLEY2711-K5A2PANELVIEW550AllenBradley2711-B5A8/F|PanelView550AllenBradley2711-T5A16L1/B|PanelView550AllenBradley2711-K5A2/E|PanelView550#1AllenBradley2711-K5A9/H|PanelView550AllenBradley2711-K5A2/F|PanelView550#2ALLENBRADLEY2711-B5A1SERIESFREVGPANELVIEW550AllenBradley2711-K5A2/F|PanelView550#3AllenBradley2711-K5A2/F|PanelView550#4AllenBradley2711-T5A1L1|PanelView550AllenBradley2711-K5A2/F|PanelView550#5AllenBradley2711-K5A8/H|PanelView550AllenBradleyPanelview5502711-B5A5Ser.EIntefaceAllenBradley2711-K5A8/G|PanelView550AllenBradley2711-B5A8/H|PanelView550AllenBradley2711-T5A5L1/B|PanelView550AllenBradleyCat#2711-K5A1PanelView550AllenBradleyCAT#2711-B5A2Panelview550AllenBradley2711-T5A8L1PanelView550DH+AllenBradley2711-B5A2/H|PanelView550#3ALLENBRADLEY2711-B5A1SERIESFREVGPANELVIEW550AllenBradley2711-B5A8/G|PanelView550AllenBradley2711-K5A8/G|PanelView550AllenBradley2711-K5A2/E|PanelView550#2AllenBradley2711-B5A8/H|PanelView550AllenBradley2711-K5A1L1/H|PanelView550AllenBradley2711-B5A2/E|PanelView550#4AllenBradley2711-K5A8/H|PanelView550*NNB*NiceABAllenBradleyPanelView5502711-T5A20L1SerBAllenBradley2711-B5A2/H|PanelView550#2AllenBradleyPanelview550Cat#2711-K5A5SerEUSEDAllenBradleyPanelview5502711-K5A5InEnclosureUsed*NEW*AllenBradley2711-K5A5/F2711K5A5PanelView550ALLENBRADLEYPANELVIEW550M/N2711-K5A2,2711K5A2ALLEN-BRADLEY2711-K5A5PANELVIEW550INTERFACEDISPLAYAllenBradleyPanelview5502711-B5A2AllenBradley2711-K5A2/E|PanelView550#3AllenBradley2711-K5A2/F|PanelView550#9*NEW*AllenBradleyAB2711-T5A5L1/BPanelView550AllenBradley2711-K5A8L1/G|PanelView550AllenBradley2711-K5A2/B|PanelView550#2NEW!!!AllenBradleyPanelview5502711-K5A5SERGAllenBradley2711-B5A3Panelview5502711B5A3ALLEN-BRADLEY2711-T5A8L1PanelView550Allen-BradleyPanelview550SeriesF2711-K5A2AllenBradley2711-K5A3/EPanelView5502711-K5A3/ENIBALLENBRADLEY2711-T5A2L1PANELVIEW550Allen-BradleyPanelview550SeriesF2711-B5A8!WOWALLENBRADLEYPANELVIEW5502711-K5A2CREVB1.07USEDAllen-BradleyPanelView550Keypad2711-B5A8AllenBradleyPanelView5502711-K5A10SerFWorkingAllenBradleyPanelview5502711-B5A1SerCRevCAllenBradleyPanelView550,2711-B5A3,ExcellentDH-485CommunicationandRS-232PrinterPortAllenBradleyPanelView5502711-B5A2InterfacePanelBAllen-Bradley2711-B5A5,SERE,Panelview550AllenBradleyPanelView550,2711-B5A5,GoodConditionTouchScreenandKeypadwithRS-232(DH-485)CommPort)
