Accessories include:• Ground fault/jam protection module(CEP7-1EF only)• Remote reset solenoid• Anti-tamper shield• Electronic remote indication display CEP7–ERID, with or without reset (CEP7–1EF units only)• External reset adapter • DIN rail/Panel adapterOverload Performance• Current Measurement-based Protection Current measurement-based overload protection more accurately models amotor’s thermal condition. Ambient temperature over the specified temperature operating range does notimpact the performance of current measurement-based designs.• Electronic Design Thermal model-ing is performed electronically withprecision solid-state components, us-ing a state-of-the-art microprocessor.The microprocessor continually pro-cesses motor current data to accurately maintain the time-current status of the motor thermal capacity utilization (%TCU) value.• Thermal Memory A thermal mem-ory design lets the CEP7-1 OverloadRelay model the heating and cooling effects of motor on and off periods. This achieves accurate protection for both hot and cold operation.• Phase Loss Protection Phase loss detection is incorporated into the CEP7-1 Overload Relay, allowing it to respond quickly to this type ofcondition.Direct Mount Mechanicalattachment800A100A 100A 100A3r d G e n C E P 7 O v e r l o a d sB1.3visit /ecatalog for pricing and the most up to date informationVersatile and Expandable• Adjustable Trip Class and Reset Modes The Basic CEP7-1EE relay of-fers Trip Class 10 and 20 with manual reset only. The Advanced CEP7-1EF relay offers Trip Class 10, 15, 20, and 30 with a selectable dial, in manual or automatic reset.• Pass-through Design The CEP7-1 relay Pass-through option consumes less panel space than a standard CEP7-1 relay that is configured with a panel-mount adapter. The pass-through design provides integrated DIN Rail mount and panel mount-ing holes. The CEP7-1 Pass-through Electronic Overload Relay provides the same protection and expandable accessory capabilities as a standard CEP7-1 relay.• External CTs For motor overload protection applications above 100A in current sensing capability, the CEP7–1EF_Z relay offers functionality with external CT configurations up to 800A maximum capacity.Wide current adjustment rangeThermal or bimetallic overload relays typically have a small current adjust-ment range of 1.5:1 meaning that the maximum setting is generally 1.5 times the lower setting. Sprecher + Schuh’s CEP7-1 overload relay is capable of adjustment to a maximum of five times the minimum set current, which dra-matically reduces the number of units required on-hand to cover the full range of current settings up to 100 amperes.Selectable tripping classBoth the CEP7-1 models have standard Class 10 tripping characteristics. The CEP7-1EE Basic model is equipped with dip switches that allow the select ability between Class 10 and Class 20, while the CEP7-1EF Advanced model possesses a selection dial on the face of the overload for trip classes 10/15/20 and 30. This selection feature allows you to closely match the Trip Class with the start-up time of the motor.Adaptive ProtectionRemote Reset CapabilityThe CEP7-1EF relay offers optional remote reset capabilities through the use of an electro-mechanical reset solenoid or an electronic remote reset accessory module.Ground Fault and Jam Protection The CEP7-1EF relay offers optional ground fault and jam protectionthrough the use of an accessory module. The ground fault current detection level is configurable via a mechanical rotary dial from 0.02…5A. Jam protection is configurable via two mechanical rotary dials, current level from 125…600% FLA, and delay from 0.1…10 seconds.Robust designThe CEP7 has been designed to physi-cally extend to the back-pan therefore aligning the mounting of the overload with the corresponding contactor. Further, the mechanical attachment and direct electrical connection to the contactor provides a robust mounting, which means less damage from shipping or during field wire installation. The bipolar latching relay which controls the normally closed trip contacts and nor-mally open alarm circuit contacts have been self-enclosed, therefore insulating the electromagnet and shielding against airborne metal particles and other po-tential environmental debris. The CEP7 has been tested to operate in -20° C. or up to 60° C (140 °F.) and withstand 3G of vibration or 30G of shock on a mountain up to an altitude of 2000m or in a jungle at 95% humidity. Reliability under every conceivable environmen-tal condition is a quality built into the design of the CEP7 electronic overload relay.Increased accuracy and improved motor protectionMicroelectronics provide flexible and ac-curate motor overload protection. Unlike traditional overload relays that simulate heat build-up in the motor by passing current through a heater element, CEP7 solid state overload relays measure motor current directly through integrated cur-rent transformers. The transformers, in turn, create a magnetic field that induces DC voltage onto the ASIC board. The electronics identify excessive current or loss of phase more accurately, and react to the condition with greater speed and reliability than traditional overload re-lays. In addition, CEP7 solid state relays offer setting accuracies from 2.5 – 5% and repeat accuracy of 1%.Dramatically lowered energy requirement saves money, reduces panel spaceBecause traditional overload relays work on the principle of “modeling” the heat generated in the motor (recreating the heat in the bimetal elements or heaters), a significant amount of energy is wasted. In traditional bimetallic overload relays, as many as six watts of heat are dissipat-ed to perform the protective function. Because the CEP7 uses sampling tech-niques to actually measure the current flowing in the circuit, very little heat is dissipated in the device…as little as 0.5 watts. This not only reduces the total amount of electrical energy consumed in an application, but it can also have a dra-matic impact on the design and layout of control panels. The density of motor starters can be much greater because less heat is generated by each of the individ-ual components. Higher density results in smaller control panels. In addition, special ventilation or air conditioning that might have been required to protect sensitive electronic equipment such as PLC’s can now be reduced or eliminat-ed. CEP7 overload relays dramatically reduced energy requirement saves moneyand reduces panel space.CEP7-1EF Selectable Dial for • Manual vs. automatic• Trip class 10, 15, 20 or 30)CEP7-1EE SwitchSelection for Trip class (10 or 20)3r d G e n C E P 7 O v e r l o a d sB1.4visit /ecatalog for pricing and the most up to date information➊ This reference is not intended to be a guide for selecting contactors.

If all the current to the motor returns through the lines in the sensor window, no significant current will be induced in the sensor secondary. If, however, ground fault current returns via a path external to the sensor, such as via the conduit walls, a current will be induced in the sensor secondary. This current will be sensed and amplified by solid state circuits. If the ground fault current is larger than the selected ground fault trip level of the overload relay, the overload relay will trip.➊ For a three phase system with one cable per phase.➋ For a three phase system with two cables per phase.CEP7-1 Ground Fault Sensor InstallationGround Fault Sensor Control WiringMotorL2L3L1GroundFault SensorBCEP7Overloadsvisit /ecatalog for pricing and the most up to date informationT2T31314A1A2659798Specifications - CEP7 Electronic Overload RelayThis section contains specifications, wiring diagrams, andcertification information for the CEP7 Electronic OverloadWiring DiagramsThe figures in this section illustrate various wiringconfigurations for the CEP7 Electronic Overload Relay and95T2T3T19697Connection must beShort-circuit Protection Deviceonnection must be tted by the userShort-circuit Protection Device Transformer Overload Relay Application and Installation Instructions, publication193-IN084.Current TrShort-circuiProtection DT1/2For more inBulletin 19InstructionTransforme193-IN0843r d G e n C E P 7 O v e r l o a d sB1.8visit /ecatalog for pricing and the most up to date informationAttributeRatingCEP7-1EE..CEP7-1EF..Type of Relay Ambient Compensated Time-DelayPhase Loss SensitiveNature of Relay Solid-state FLA Setting Rotary Dial Trip Rating 120% FLATrip Class 10, 2010, 15, 20, 30Reset ModeManualAutomatic or ManualOverload ResetLevelAuto Reset occurs at 70% TCU when accessory powered, after 2 minutes when self powered.Manual Reset can occur anytime by pressing themanual reset button.

Only qualified personnel should perform this installation. For additional information regarding installation, wiring and operation of this device, refer to the appropri-ate document listed in Table 2. If you require further information regarding a particular installation, application, or maintenance activ-ity, please contact your Eaton representative or Eaton’s Technical Resource Center at 1-800-809-2772, Option 4, sub-option 2. This Quick Start Guide is not intended to cover all details, variations or combinations of the device’s storage, delivery, installation, operation or maintenance.1.1 Safety precautionsWARNINGWARNING – SHOCK HAZARD – DO NOT OPEN.AVERTISSEMENT – RISQUE DE CHOC – NE PAS OUVRIR.WARNING NO SERVICEABLE PARTS.ATTENTION : AUCUNE PIÈCE REMPLACABLE OU RÉPARABLE.A LICENSED/QUALIFIED ELECTRICIAN MUST COMPLETE ALL INSTRUCTIONS IN THIS GUIDE IN ACCORDANCE WITH THE NATIONAL ELECTRIC CODE (NEC), CANADIAN ELECTRIC CODE (CEC), STATE, COUNTY AND LOCAL SAFETY RATINGS, OR OTHER APPLICABLE COUNTRY CODES. ALL APPLICABLE LOCAL ELECTRICAL CODES SUPERSEDE THESE INSTRUCTIONS.IMPROPER WIRING COULD CAUSE DEATH, INJURY AND/OR EQUIPMENT DAMAGE. ONLY LICENSED/QUALIFIED ELECTRICIANS WHO ARE TRAINED IN THE INSTALLATION AND SERVICE OF ELECTRICAL SERVICES ARE TO INSTALL AND SERVICE THIS EQUIPMENT.CHECK THE VOLTAGE-RATING LABEL LOCATED ON THE SIDE OF THE SPDTO VERIFY THAT THE ELECTRICAL SYSTEM’S VOLTAGE AND WIRING CONFIGURATION ARE THE SAME AS THE SPD.CONDUCTING DIELECTRIC, MEGGAR, OR HI-POTENTIAL TESTING WITH THE SPD INSTALLED WILL CAUSE INTERNAL DAMAGE TO THE SPD. THE SPD WILL CAUSE THE TEST TO FAIL.IMPROPER INSTALLATION COULD CAUSE DEATH, INJURY AND EQUIPMENT DAMAGE. FOLLOW ALL WARNINGS AND CAUTIONS. COMPLETELY READ AND UNDERSTAND THE INFORMATION IN THIS GUIDE BEFORE ATTEMPTING TO INSTALL OR OPERATE THIS EQUIPMENT.ARC FLASH DURING INSTALLATION COULD CAUSE INJURY OR DEATH.USE APPROPRIATE SAFETY PRECAUTIONS AND PERSONAL PROTECTION EQUIPMENT FOR ARC FLASH PROTECTION.CHECK THE FACILITY’S GROUNDING SYSTEM. ALL GROUNDING, BONDING AND EARTHING PRACTICES MUST MEET NEC, CEC AND LOCAL APPROVED PRACTICES. A POOR GROUND, OR A GROUNDING / BONDING VIOLATION WILL SERIOUSLY AFFECT THE SPD’S ABILITY TO FUNCTION AS SPECIFIED. INSTALLING AN SPD THAT IS IMPROPERLY RATED FOR THE ELECTRICAL SYSTEM VOLTAGE COULD CREATE A POTENTIALLY HAZARDOUS CONDITION, RESULTING IN INJURY OR EQUIPMENT DAMAGE.WHEN MOUNTING THE SPD OUTDOORS, USE WEATHERPROOF CONDUIT AND FITTINGS TO MAINTAIN THE ENCLOSURE’S NEMA RATING.FOR USE ON CIRCUITS DELIVERING UP TO 5000 RMS AMPS.CONVIENT Á DES CIRCUITS PRODUCISANT AU PLUS 5000 A EFF. 1.2 Enclosure dimensionsRefer to the appropriate document listed in Table 2 for unit size and dimensions.1.3 Directly mounted to electrical panel – preferred method The preferred installation of the SPD is to mount it directly to the electrical panel. For Type 4X applications use the supplied mounting feet to secure the device.Figure 1. Preferred Installation.1.4 Directly mounted to electrical panel with conduit – alternate methodAn alternate installation method is to install the SPD with a pieceof short, straight conduit. Avoid using 90° conduit elbows and keep the conduit run as short and straight as possible. In this application, install the SPD as close as possible to the electrical panel. For Type 4X applications use the supplied mounting feet to secure the device.Figure 2. Alternate Installation.2 Wiring installationLocate the electrical system’s applicable wiring schematic from Section 3. Wiring diagrams and refer to it while wiring the SPD. TURN OFF power to the electrical equipment being connectedto the SPD in accordance with NEC, CEC, state, county and local codes for all safety ratings.Eaton SPD’s covered in this guide are designed with internal overcur-rent protection and do not require an external overcurrent protection device (OCPD) unless otherwise required by NEC, UL, and local electrical requirements to protect electrical conductors. NEC Article 310.15 (B) (16) defines the maximum rating of the OCPD required to protect the electrical conductors. NEC shows #10 AWG conductors at 60°C typically requiring a 1-pole (for single phase systems), 2-pole (for split-phase systems) or 3 pole (for 3-phase systems) 30A branch circuit breaker to protect SPD conductors.Twist and bind the wires of the SPD tightly together. Minimize over-all lead length to optimize SPD performance. To maximize the SPD’s performance, phase wire length should be less than 14” (35cm) twisted and bound together. For wire lengths longer than four inch-es, phase wires should be twisted once for each four inches of wire length to maximize performance.If the SPD is configured for remote monitoring (not available on all models), connect the Form C relay contact wiring to an alarm or building monitoring system. Refer to the appropriate document listed in Table 2 for Form C relay ratings.otee:N Utilization of Form C contacts is optional. Connection of Form C wiresis not required for the proper operation of the SPD.Eaton1000 Eaton Boulevard Cleveland, OH 44122United States © 2016 EatonAll Rights Reserved Printed in USAPublication No. IL158001EN / TBG001324August 2016Eaton is a registered trademark.All other trademarks are property of their respective owners.Eaton SPC series surge protective devicequick start guideInstruction Leaflet IL158001ENEffective August 2016Tighten and recheck all connections and mounting before proceeding to Section 4.

Switch main panel power to ON and then switch SPD branch circuit breaker(s) to ON, if applicable. One LED should light for each phase voltage being monitored. Single phase electrical systems will light only one LED, split phase systems light two LEDs, and threephase systems will light all three LEDs.If the connected LEDs do not light, remove power, re-check connec-tions, and test again. If the LEDs still do not light, contact your local authorized distributor or the Eaton Technical Resource Center, as the SPD may be damaged.4.2 LED color statesWhen properly installed, only green status LED’s should be ener-gized. Refer to the appropriate document listed in Table 2 for more information regarding SPD LED color states.5 MaintenanceThe Eaton SPD devices covered in this guide are self-contained devices that do not require maintenance or contain serviceable parts. If any LED changes state, the unit has lost surge protection and must be replaced.

1.1电保持型断路器控制分合闸的功能1.1.1电保持型断路器通过旁路断路器线圈Q的电阻R来合闸,在合闸后只需流过很小的电流即可使断路器保持在合闸位置。
)其合闸顺序为:SEPCOS输出1s脉冲,使电阻R旁路继电器K1得电,旁路电阻R。
500ms后SEPCOS发出合闸脉冲并保持,断路器合闸线圈得电合闸。
)其分闸顺序为:使合闸保持线圈Q失电,断路器分闸。
1.1.2监视断路器状态1.2磁保持型断路器控制分合闸的功能1.2.1磁保持型断路器的合闸线圈为短时通电型。
)其合闸顺序为:SEPCOS输出1s脉冲,接通合闸继电器K1,合闸线圈Q得电,断路器合闸,合闸后合闸线圈Q失电。
线圈失电后,断路器通过永磁机构保持合闸状态;)其分闸顺序为:SEPCOS输出1s脉冲,接通分闸继电器K2,使合闸线圈Q流过反磁极电流,给永磁机构消磁,断路器分闸,分闸后合闸线圈Q失电。
1.2.2监视断路器的状态。
1.3联跳功能当SEPCOS检测到一个故障(保护故障或大电流脱扣),跳开断路器并发送联跳输出信号。
同时使给该段线路或该段网络供电的所有断路器跳闸并锁定。
)在远方模式,自动重合闸功能投入,联跳输出信号是持续保持的,直到SEPCOS收到分闸,复位命令或合位信号。
)在远方或就地模式,自动重合闸功能没有投入,联跳输出信号持续2秒。
跳闸并闭锁同一段网络供电的所有断路器。
断路器重合闸后,SEPCOS取消联跳输出信号,其它被联跳的断路器则被允许重合闸。
SEPCOS接受到联跳输入信号,跳开断路器,然后等待联跳输入信号消失,从而继续执行本柜控制程序。
)在就地模式,保持跳闸状态,直到联跳输入信号消失或SEPCOS收到合闸命令。
)在远方模式,保持跳闸状态,直到联跳输入信号消失并自动合闸断路器。
联跳顺序:当馈线柜A附近线路产生故障,SEPCOS A打开故障保护检测,发出联跳输出信号给SEPCOS B,SEPCOS B接受到联跳输入信号并跳闸。
两种可能性:)在就地模式:没有自动重合闸功能,SEPCOS A发出2秒联跳输出信号。
)在远方模式:有自动重合闸功能,SEPCOS A接受到断路器(A)合位信号时,停止发送联跳信号。
这时SEPCOS B停止接受SEPCOS A的联跳信号,并开始自动重合闸和线路测试。
SEPCOS在从联跳信号发出到信号消失过程中不响应联跳输入信号;SEPCOS接收到联跳输入信号到信号消失过程中不发送联跳输出信号。
相邻变电所间的双边联跳:当本变电所一台断路器跳闸时,必须使相邻变电所内向同一区间供电的断路器同时跳闸;其功能可通过联跳电缆及两侧直流开关柜中的联跳继电器来实现,每条馈线SEPCOS数字式保护监控单元的联跳接收与发送采用独立的回路。
其具体实现过程为:首先,当故障发生于某一区间时,变电所A内馈线柜的SEPCOS专用微机型继电保护和控制综合装置检测到故障,发出信号使馈线柜断路器跳闸,并发出联跳发送信号。
然后,经相邻变电所之间的联跳电缆,将此联跳信号发送到相邻变电所B内的向同一区间供电的馈线柜内。
最后,经邻所馈线柜的联跳接收继电器进入SEPCOS专用微机型继电保护和控制综合装置,使邻所馈线断路器跳闸。
如A所内馈线断路器未启动自动重合闸功能,联跳信号维持2秒;如重合闸功能投入,在A所馈线断路器经重合闸过程处于合位时停止联跳信号的发送,从而使B所的馈线断路器能重合闸(如重合功能投入)。
1.4自动重合闸功能/防跳自动重合闸是指在线路出现故障断路器分闸后,经过一定延时Delay[s]后,SEPCOS发出重合闸命令,经线路测试,使断路器自动重合闸。
如果断路器在防跳功能中设定的时间间隔T[s]内又被跳开,则计数一次,若被跳开的次数达到预先设定的次数N,则断路器被闭锁。
重合闸延时Delay[s]、防跳设定次数N和防跳的时间间隔T均可调参数说明:Delay:(自动重合闸)两次成功合闸间隔的最小长时间。
N:(防跳) 防跳设定次数。
允许断路器按防跳间隔时间T连续分合闸的最高次数。
T:(防跳)防跳的时间间隔。
重合闸成功开始计时,直到断路器调整计时结束。
T*:自动重合闸最大允许延时=正常操作的最坏的事件中重合闸必须的延时=线路测试最大持续时间+自动重合闸持续时间+4s(安全时间)。
参数设定:参数单位范围Delay[S] 1~30SN [-]1~5次T [S] 3~20S1.5线路测试功能在断路器合闸前,对线路进行测试,以防止断路器合闸于故障线路上。
典型的测试线路原理图如下图所示,通过旁路来测试线路状况。
整个测试回路由电阻,熔断器,接触器和采样模块组成,将母线电压通过测试回路加到馈线回路,测量回路电阻来判断是否可以合闸。
线路测试次数N、两次测试的间隔D、每次测试的时间T均可调。
下面就几种情况分别加以阐述。
1.测量馈线电压U f,如果馈线电压U f≥U f Low(此时线路已由另一断路器供电),直接合闸本所断路器。
2.测量馈线电压U f,如果馈线电压U f Low> U f>U f Residue,)在“就地”模式下,线路测试停止,断路器不能合闸并闭锁;)在“遥控”模式下,则连续进行线路测试N次,每次时间间隔D,若线路中故障仍存在,线路测试停止,断路器不能合闸并闭锁。
3.测量馈线电压U f,如果馈线电压U f<U f Residue,且U r >U f Low,闭合线路测试用接触器T秒,将U r加到线路上,测量线路的回路电阻R。
如果电阻R > R min,则断路器合闸。
如果电阻R min > R:)在“就地”模式下,线路测试停止并闭锁断路器;)在“遥控”模式下,连续进行线路测试N次,每次时间间隔D,若线路故障存在,线路测试停止,断路器不能合闸并闭锁。
4.测量馈线电压U f,如果馈线电压U f < U f Residue,且U r < U f Low,)在“就地”模式下,断路器不能合闸并闭锁;)在“遥控”模式下,则连续进行线路测试N次,每次时间间隔D,若线路中故障存在,线路测试停止,断路器不能合闸并闭锁。
参数说明:T:母线电压施加的时间。
N:线路测试次数。
R min:回路最小允许阻抗。
U f Residue:残压,线路最小电压,在此电压下,线路测试必要时,时间不再有效。
U f Low:最小允许车辆运行电压D:两次线路测试成功的时间间隔。
参数设定:参数单位范围N [-] 1~10次D [s]10~120ST [s]1~4SR min[mΩ] 300~10000 mΩU f Residue[V] 0~500VU f Low [V] 300~2000V2.保护功能2.1 电流测量2.1.1 Imax+保护有时线路中的故障电流(过载电流或短路电流)小于断路器的大电流脱扣整定值,通过测量、分析馈电回路的正向电流If,可检测出低于断路器整定值的短路电流和过载电流。
测量正向电流If,如果If >设定的I max+,SEPCOS开始计时,如果当计时t >设定的T Imax+,则发出跳闸指令。
参数说明:I max+:相应线路上的车辆启动或运行时,在定义的T Imax+期间可容纳的最大电流值。
I max+ <I cc min (末端短路电流)。
T Imax+:T Imax+ > T start(机车启动的时间)。
参数设定:参数单位范围I max+ [A]0~8000AT Imax+ [ms]0~65000 ms2.1.2 Imax-保护通过分析馈电回路的反向电流If,检测低于断路器大电流脱扣整定值的故障电流。
测量反向电流If,如果If<设定的Imax-,开始计时,如果t>设定的T-,发出跳闸指令。
参数设定:参数单位范围I max-[A]0~8000 AT Imax-[ms]0~65000 ms2.1.3 DDL+保护此保护功能用来监测在线断路器的远方故障(短路故障),通过分析电流上升率di/dt与两个可调整的参数Slope E和Slope F来比较实现的。
通过分析馈电电流上升率di/dt、电流增加的时间t及电流增量∆I,检测中远距离短路故障,其故障电流值低于断路器的整定值。
测量馈电电流及其di/dt,将测量di/dt与设定值Slope E和Slope F比较。
)如果测量di/dt > Slope E,则开始测量电流增量(∆I)并计时(t),1.如果测量值∆I >∆I max,且时间t >t ∆I max,则发出跳闸信号;2.如果计时时间t > T max,且电流的增量∆I > 设定值∆I min,则发出跳闸信号。
)如果在检测到∆I max或T max之前,di/dt< Slope F,且经一定时间延迟后,∆I和t复零。
参数说明:Slope E:斜率E。
此参数用于启动DDL保护功能的条件,起始斜率根据(di/dt)t=0来计算。
如果在短路电流产生时已有牵引电流(在t=0 , I=I traction > 0 ),起始斜率低于在I=0,t=0极限情况下的计算值。
因此,为使在有牵引电流时正常检测,Solpe E设定为在( di/dt ) t=0时计算值的0.5倍。
如果牵引电流较高(这时初始斜率较低),为了能够识别短路电流,此设定值可以设定的更低一些,但是不能太低以防与牵引电流混淆。
Slope F:斜率F此参数作为DDL保护功能分析结束的条件,此斜率表示短路电流结束。
为了使DDL的参数T的值测量精确,可以将此值设置得低一些。
换句话讲是为识别更多发生在线路末端的短路情况,但检测时间将迅速增加。
现在有两个条件来判断保护分析是否结束:)Sepcos在电流曲线上取连续四个点的平均值与Slope F比较(此平均值只取自F)当此平均值大于等于Slope F延迟2秒,停止DDL分析。
