With INCOM interface, DT 3000 can realize data sharing and remote control with remote upstream host computer. Its protection feature generally provides phase components and ground components with: inverse time overcurrent protection, short delay time protection, and instantaneous overcurrent protection, overload alarming, regional interlocking. Complete self-inspection function ensures the device to provide reliable protection for primary equipments. Thismicroprocessor-based protection relay can display intuitively graphic operating characteristic curve types on the panel, with dual-window indication of fault information. Besides, it has a special indicator light for indication in case of remote tripping control. With DIP dial switch configuration on the back panel of the device, an even superior protection solution can be offered as well.Testing functionThis mode can be used in regular inspection of relay’s protective function (can select tripping or no-tripping). But when its single phase or ground current is inspected to be 0.1 times higher than primary rating current of CT, the device will automatically set back to testing mode with indication of “ERR” information.Other special functionsAutomatic reset function: additional automatic reset function can be provided for protective operating signals (condition is when the current falls below 0.5*In)Programmable protection output relay: same output relay can allocate different protection function outputs.Withdrawable structure: when relay basic device is withdrawn from its housing frame, the device will automatically be short connected to CT circuit and automatically switch off I/O and power supply circuit, ensuring safety of personnel and equipments.Each protection function is independent from each other. They can meet requirements for all kinds of systems, when used in combination with other functions.Regional interlocking functionCan quickly remove regional protection of inverse time and short delay time as a response, replacing expensive busbar differential protection Communication functionDT3000 provides function for communication with PowerNet system, monitoring remotely the operation status of primary equipments. Real-time operation parameters can be viewed on the panel and transmitted to PowerNet via INCOM interface:Real-time operating information inquiryGive remote command for switching circuit breakers Reset relay devices after closing Download protection set pointsInverse time overcurrent protection Short delay time overcurrent protection Instantaneous overcurrent protection Overload alarming and node output Tripping protection for discriminatorRegional interlocking protection for hierarchy switchesSingle phase current Ground currentMaximum ground and phase currents since the last reset Current level and phase position causing tripping Tripping causesCurrent transformer ratioSetup values for each current setup options Software versionStatus of circuit breakersRemote control functionBased on PowerNet protocol, INCOM interface allows remote monitoring system to control operations for local primary equipments, including:I 4t ItFLAT I 2t3Dual power supply: when normal power supply voltage for the device falls down to 75% of voltage rating, the device will start CT circuit for power supply. Even in the case of normal power supply faults, theprotection function can still work, providing reliable protection constantly for operating equipments.Introduction of protection functionDT 3000 provides 11 types of protection characteristic curves for primary equipment in medium voltage power distribution system, as shown below.DT3000 Microprocessor-based feeder, transformer backup protective relay Key featureCharacteristic curve diagram of DT 3000 overcurrent protective relay’s phase components and ground componentsExplanation ：In the characteristic curves of ANSI and IEC ，the unit for horizontal axis is Ipu (CT primary operate value),while in short delay time and instantaneous curves, the horizontal axis unit is In(primary current value when CT secondary current at 5A).In the case of thermal tripping curve, horizontal axis units are In for all the threecircumstances, which shall be distinguished in coordination and programming.Inverse time overcurrent protectionInverse time overcurrent protection is set up ， including curve types, operate values, set up of inverse-time time-factor. Operate value setup item sets up current level when inverse time current tripping function begins timing. If after the pre-setup time, overcurrent conditions still exist, then tripping relay of the device will operate.The picture on the right shows how the inverse time overcurrentThe above is a typical short delay operate-value setup. The dashed line section is shown when users select different operate-values; thesame short delay time setup is the dashed line combination vertical to time axis, as shown belowShort delay time overcurrent protectionShort delay time overcurrent protection is responding to short circuit condition faults. The set-up items include current operate value setup and delay setup. The former is the current level of the overcurrentwhen this protection begins timing. The latter is the time size from the beginning of timing till operating tripping.operate value passes operate value set-up and make horizontal movement along time-current coordinate system.① Curve refernce standard: ANSI C37.112② Curve refernce standard ：IEC 255-3current Thermal trip curveZ SI f52The circuit breaker charged负荷DT3000With DSPSac power supplyLoadDT-3000带DSPSV 0≌CurrentANSI curve ①Current IEC curve ②InstantaneousFixed extreme Severe Exteme InstantaneousCurve graphicCurve graphic SevereShort delayShort delayc u r r e n t时间Dashed range composed by short delay operate valuesCurrentt i m ec u r r e n tI nc u r r e n tRated current muliplesInverse timeMinimum operate valueDT3000 Microprocessor-based feeder, transformer backup protective relay Aug-2011505150G 51G4DT3000 Microprocessor-based feeder, transformer backup protective relayKey featuresCurrentCurrent3 phase overcurrent protection3 phase quick-break ground overcurrent protection Ground overcurrent protection Regional interlockingPhase component regional interlocking terminal: TB1-13,14，Ground component regional interlocking terminal: TB1-11,12，When this function is not used, they should be short connected separately.Protection function list and respective ANS I standard codest i m eDashed range composed by short delay operate valuesInstantaneous fixed valueOverload alarmingWhen load current reaches 85% of phase component inverse time overcurrent operate-value, overload function starts timing, with “High load” LED flicking in red. If the current is below 85%, the timer will reset. Only when the current reaches 85% again, the timer will restart. When there are 3 times of timer overtime:：1、”High Load”LED on relay’s panel keeps in red.2、Alarming signal transmitting to the whole communication network3、If DIP-5 is in “0N” position, closed terminals TB2-4 and TB2-5conduct overload signal node output. When the current is below 85%, the relay returns.Regional interlocking functionWhen subordinate protection device sends out tripping signal, it will generate a 175ms-delay regional interlocking signal to superiorprotection device. Before the superior protection device responds to the fault, the subordinate protection device clears faults during this period. When the signal ends, if the current does not fall down below the fixed value, then the superior protection device will operate immediately for tripping.Please be noted that in the case of coordination of short delay and inverse time curves, the minimum tripping time of inverse time shall not be lower than short delay time operate-value, otherwise it will cause protection chaos.Instantaneous overcurrent protectionInstantaneous operating protection reacts to big fault current condition with two cycles as responding time to faults. When instantaneous protection is set as “NONE”, the device provides discriminatorprotection function. That is, if and only if during the first 10 cycles after closing the circuit breaker, if the load current exceeds 11*In, the discriminator export will operate instantaneously. If it’s more than 10 cycles, then it will operate when next time the circuit breaker closes from its opening position.Ground fault protectionGround fault protection has below three protection set-up ：1、Inverse time overcurrent curve, operate-value, time setup ；2、Short delay overcurrent protection operating value and time setup ；3、Instantaneous operating protection operate-value. Ground curve shape is independent from phase component curve shape.In addition, below are other differences between them: in thermal curves, when the inverse time overcurrent time factor to ground is 1*In;n, time factor to phase is 3*In;When ground instantaneous protection is set as “NONE”, ground instantaneous protection will be shielded completely, without providing discriminator distinction protection.DT3000 Microprocessor-based feeder, transformer backup protective relay Aug-20115DT3000 Microprocessor-based feeder, transformer backup protective relay T echnical dataTechnical dataTesting standardsCertification ：Current inputCUL ／UL ，recognized (file# E154882)CAN ／CSAC22.2 14.M91UL 1053(6#，1999 version) ANSI C37.90(1989)EN 61010-1(1993)-limited to DT303* EN 55011(1991)Radiation testsEN 55011(1991) Class A, Type 1FCC47 CFR~ Chapter 1, Part15, Class A Immunity testANSI C37.90.1 (1989) surge capacity 2.5kV OSWC 4kV FTSWCANSI C37.90.1 (1995)-RFRadiation capacity 35V ／M- all modes EN61000-4-2(1995)-ESD immunity 8kV IEC255-22-2(1989)-ESD immunity 8kVEN61000-4-3(1995) frequency radiation immunity 10V/m IEC255-22-3(1989) frequency radiation immunity1 0V/m EN61000-4-3(1995) fast transient 10V/m IEC255-22-4(1995) fast transient 10V/mEN61000-4-5(1995) surge immunity2/1kV C/DMEN61000-4-6(1995) frequency carrying immunity 10Vo EN61000-4-11(1994) voltage dip\ fluctuation\ intermittent interferenceInsulation strengthCurrent input end: 3000V 1m, phase to phase Seismic testIn accordance with UCB requirements and California lawOutput tripping node(Tripping OC ／Comm ，Trip Inst&CommColse) Instantaneous 30A ac ／dc 0.25 second Breaking 0.25A 250Vdc Breaking 5A 120／240Vac Continous 5A@ 120／240VacReference ANSI C37.90 Chapter 6.7Control power supplyCT secondary rating CT loadSaturation value28*InInstantaneous value Ct thermal parameter5A<0.04 Ohm<0.1VA @ rated current (5A)30 *In(Chicago version) 100*In 1second 10A continuous 500A 1secondRatingOperating ValueConsumption power48V-250Vdc 120-240Vac 24V-48Vdc28V-280Vdc 66-264Vac 19V-56VdcDT3000DT3030DT3000 (DC)48V 125V 250V 120V 240V 10VA 10VA 10VA 10VA 10VADT3100(DC)48V 125V 250V 120V 240V 10VA 10VA 10VA 10VA 10VADT3030 10VA MaximumPhase components and ground components time current curveThermal modeANSIANSI C37.112 1996IECIEC255-31989(moderate inverse time)(very inverse time) (extreme inverse time) (fixed time)(moderate inverse time)(very inverse time)(extreme inverse time)(moderate inverse time)(very inverse time)(extreme inverse time)(fixed time)It I2t I4t FLATIEC-A IEC-B IEC-C IEC-DDT3000 Microprocessor-based feeder, transformer backup protective relay Aug-2011DT3000 Microprocessor-based feeder, transformer backup protective relayT echnical dataCT ratio (primary)set range：Phase ＆ ground components10/25/50/75/100/150/200/250/300/400/500/600/630/800/1000/1200/1250/1500/1600/20002400/2500/3000/3200/4000/5000Phase ＆ ground components (Chicago version)5/10/25/50/75/100/150/200/250/300/400/500/600/630/800/1000/1200/1250/1500/1600/2000/2400/2500/3000/3200/4000/5000Time precision：Counter delay overcurrent time ±10％ 1.5IpuShort delay time±50msTime delay setCounter delay overcurrent time factor：IT 12T 14T Curve：0.2~40148 alternative values]IT 12T 14T Curve：0.2~40[48 alternative values]( Chicago version)Fixed time：0.2-2.0[2 1 alternative values]ANSI(all)：0.1-5.0[50 alternative values]IEC(all)：0.025-1.0[40 alternative values]IEC(all)：0.05-1.0[20 alternative values]( Chicago version)Short delay：O.05-1.5[22 alternative values]Auxiliary relayContinuous 5A@120／240Vac5A@30Vdc5A continuous (Chicago version)Communication function：Compatible to PowerNet／via INCOMBaud rate：1200bps or 9600bpsAddress：INCOM setting up from the front panelNote 1： When the device sets overcurrent value of phase components, there is no “NONE“ option.

Installation Instructions for Undervoltage Release Mechanism (Handle Reset) for NDB, ND, NDC, NW, HNW, and NWC Circuit Breakers, Series C Molded Case Switches, and Motor Circuit Protectors (HMCP)The user is cautioned to observe all recommendations,warnings, and cautions relating to the safety of personnel and equipment as well as all general and local health and safety laws, codes, and procedures.The recommendations and information contained herein are based on Eaton experience and judgement, but should not be considered to be all-inclusive or covering every applica-tion or circumstance which may arise. If any questions arise, contact Eaton for further information or instructions.1. INTRODUCTION General InformationThe undervoltage release mechanism (UVR)(Fig. 1-1) moni-tors a voltage (typically a line voltage) and trips the circuit breaker when the voltage falls to between 70 and 35 per-cent of the UVR rating. The UVR consists of a continuous rated solenoid with a plunger and reset lever assembled to a plug-in module. The plug-in module is mounted in slots in the top of the trip unit and occupies the accessory cavity in the circuit breaker frame. The reset lever resets the UVR when normal voltage is restored and the circuit breaker handle is moved to the reset (extreme OFF) position. With no volt-age applied to the UVR, the circuit breaker contacts will not touch when a closing operation is attempted.The UVR is available with several voltage ratings for most AC and DC requirements. Table 1-1 and 1-2 list application and electrical rating data for the UVR.For this publication, the term circuit breaker shall also include molded case switch and motor circuit protector. Depending on the model ordered, connections for the UVR are in one of four forms. The standard wiring configu-ration is pigtail leads exiting the rear of the base directly behind the UVR. Optional configurations include a terminal block mounted on the same side of the base as the acces-sory, leads exiting the side of the base where the acces-sory is mounted, and leads exiting Ihe rear of the base on the side opposite the accessory. The 18-inch long pigtail leads are color coded for identificaion: identification labelsare provided for pigtail leads and terminal block points.CONTACT WITH ENERGIZED EQUIPMENT CAN RESULT IN DEATH, SEVERE PERSONAL IN-JURY , OR SUBSTANTIAL PROPERTY DAMAGE.

If any questions arise, contact Ea ton for further informa-tion or instructions.1. INTRODUCTIONGeneral InformationThe auxiliary switch (Fig. 1-1) indicates circuit breaker contacts status, and is used for remote signaling and system interlocking purposes. The switch consists of one or two single-pole double- throw (SPDT) switches assembled to a plug-in module. The plug- in module is mounted in slots in the top of the trip unit; it occupi- es the accessory cavity in the circuit breaker frame, and is positio- ned so that the switch actuator arm rests against the molded crossbar.
