Industrial Motor Control and Protection Relay

low-voltage motor circuits with rated voltage up to 660V and integrates protection, measurement, control, communication, operation, and maintenance. Its perfect protection function ensures the safe operation of the motor, with a logic programmable function, and can meet a variety of control methods. Different communication modules can be selected to meet the needs of field communication. The ARD3M intelligent motor protector (hereinafter referred to as the protector) is suitable for Product Implementation standards: --GB 14048.4-2020 Low-voltage switchgear and controlgear    -- Part 4-1: Contactors and motor starters       -- Electromechanical contactors and motor starters (including motor protectors); --JBT 10736-2007 Low voltage motor protector. The standard switch quantity of ARD3M is 10DI and 6DO, and the switch quantity type Main switch classification Code DI is the dry contact and the external power supply of DO is AC220V K1 DI is the wet contact, the input is DC110V, and the the external power supply of DO is AC220V K2DI is the wet contact, the input is DC220V, and the the external power supply of DO is AC220V K3DI is the wet contact, AC220V input, and DO external the power supply is AC220V K4This correspond to the relation between ARD3M current specification and the rated current and power of the applicable motor Protector current specification (A) Ratio setting Primary side coil number of transformerApplicable scope of motor (kW) Suitable for motor Rated current range (A) 1Support5 circle 0.12-999 0.1-5000 51 circle 25not Support3-11 6.3-25 10015-4525-10025055-13263-250800160-250250-800Additional features of ARD3M  Code Additional function H2-63 harmonic voltages and currents WRWaveform recording SUAnti-electric shock functionRiAnti-electric shock functionLElectric leakage protection SRFault record WIFIWireless function (optional with color dot matrix LIQUID crystal) CP1channel PROFIBUS DPV1communication 2CP2 channel PROFIBUS DPV1communication MCEEthernet communication (MODBUS TCP protocol) PNET1channel Profinet communicationM11channel 4-20mA output M22 channel 4-20mA output   FunctionFunctionItemARD3MApplication occasionsLow Voltage 0.4KV~1.14KV Motor ProtectionRated Current1(ratio)(0.1-5000A)5(ratio)(0.1-5000A)25(6.3-25A)100(25-100A)250(63-250A)800(250-800A)DimensionPanel mm98*60Cut-out mm92*55ProtectionStartup timeoutYesOver-loadYesUnder-loadYesShort CircuitYesStallYesBlockYesCurrent UnbalanceYesVoltage UnbalanceYesExternal FaultYesStructural FailureNoInternal FaultNoOver-voltageYesUnder-voltageYesOver-powerYesUnder-powerYesLack of phaseYesPhase SequenceYesTEYesTemperatureYesMulti-channel temperature protection Overflow protectionYesInsulation monitoringYesNumber of starts alarmYesRunning time alarmYesNumber of fault alarmYesAnti-shakeOptionalAnalog input protectionNoGroundedYesLeakage CurrentOptionalCommunicationModbus-RTUNo2 Channels of Modbus-RTUYesProfibus-DPOptional2 Channels of Profibus-DPOptionalProfinetOptionalModbus-TCPOptionalWIFIOptionalSignalDI10+DO6+Start controlYes4-20mA OutputOptional2 channels of 4-20mA OutputOptionalFault Record8OptionalRunning Record5hOptionalWaveform Record40OptionalDI Displacement Record8YesStart and stop Records8YesRestart Record8YesLogic functionTimerNoCounterNoTruth tableNoLogic diagramNoMeasureThree-phase currentYesLeakage currentOptionalThree-phase voltageYesPositive sequence negative sequence zero-sequence currentYesPositive sequence negative sequence zero-sequence voltageYesActive power, Apparent powerYesReactive powerYesFrequencyYesActive energyYesReactive energyYes2-63st HarmonicOptionalPTC/NTCYes4-20mA InputNoTemperatureNoDisplayLEDNoMonochrome LCDOptionalColor LCDOptionalProduct ParametersTechnical parametersTechnical indicatorsProtector auxiliary power supplySupport two power modules, AC 220V power module (AC85-265V/DC100-300V) default, AC 380V power module (AC/DC100-415V) optionalRated working voltage of the motorAC220V / 380V / 660V,50Hz / 60HzRated operating current of the motor1 (0.1A-5000A)External current transformer5 (0.1A-5000A)25(6.3A-25A)100(25A-100A)250(63A-250A)800(250A-800A)Relay output contact capacityImpedance loadAC250V,10ASwitching input10 channels of passive dry contact (active DC110V, DC220V, and AC220V input can be optional)CommunicationStandard supplied2channel MODBUS RTU communicationOptional(only one can be selected)1-2 channel PROFIBUS DPV1communication,1channel PROFINET communication, Ethernet communication(MODBUS TCP protocol)EnvironmentWorking temperature-10ºC~55ºCStorage temperature-25ºC~70ºCRelative humidity≤95%No condensation, no corrosive gasAltitude≤2000mPollution levelsClass 3Protection gradeMain body IP20, split display module IP54 (installed on the cabinet panel)Installation categoryLevel IIIComposition Dimension   WiringNetworking just feel free to contact me to create a cloud platform experienced accountApplicationCompany ProfileAcrel Co., Ltd.[stock code: 300286.SZ] is a high-tech enterprise that integrates R&
