Acrel Ard2f-25/L+90L Smart DIN Rail Motor Overload Leakage Current Protector Motor Protection Relay

Product DescriptionARD2F Smart Motor ProtectorGeneralARD series intelligent motor protector (hereinafter referred to as protector) can perform various conditions such as starttimeout, overload, phase failure, unbalance, underload, ground/leakage, blockage, short circuit and external fault during motor operation. Protection, and SOE fault event recording function, convenient for on-site maintenance personnel to find the cause of the fault. Suitable for coal, petrochemical, smelting, electric power, ships, and civil construction. The protector has RS485 remote communication interface, DC 4 ~ 20mA analog output, and PLC, PC and other control machines form a network system. Remote monitoring of motor operation.Features1.Measurement functions are divided into basic measurement (current parameter) and co-selection measurement (voltage, power, phase sequence, residual current (leakage current);2.Start timeout, overload, stall, block, underload, phase failure, unbalance, residual current (ground/leakage), temperature,3.external fault, phase sequence, overvoltage, undervoltage, underpower, overpower, tE time Motor comprehensive protection function;4. 9-channels DI passive dry node input, signal power supply with built-in DC24V power supply;5.5-channels DO output, which can meet the direct start, star-delta start, autotransformer start, soft start and other starting modes. Real-time remote control "start/stop" operation of the remote master station can be realized through the communication bus;6.It has standard RS485 communication interface and adopts Modbus-RTU and Profibus-DP communication protocol to ensure fast and reliable communication of the host computer;7.It has a DC4-20mA analog output interface and is directly connected to the DCS system to monitor the field devices.Technical ParametersTechnical data of motor protector ARD2F-25Auxiliary power supply of protectorAC85V~265V/DC100V~350V, power consumption ≤7VARated working voltage of motorAC380V/AC660V, 50H/60HzRated working current of motor1A(0.1 ~9999)Small specific current transformer5A(0.1 ~9999)1.6A(0.4A-1.6A)6.3A(1.6A~6.3A)25A(6.3A~25A)100A(25A~100A)250A(63A-250A)Specific current transformer800A(250A~800A)Relay output contactor, rated load capacity4-way,AC250V, 3A, DC30V, 3ASwitching input2-way, optical isolationCommunicationRS485 ModbusVolume of SOE event recorder8 eventsEnvironmentWorking temperature-10ºC-55ºCStorage temperature-20ºC-65ºCRelative humidity5%-95%, no dewAltitude≤2000mClass of pollution2Protection levelIP20Rated current of motor protector(A)current ratio settingTransformer primary side turnsSetting current Is range(A)Motor Power(kW)1able to set50.1~99990.12~440510.1~99990.12~4401.6unable to set10.4~1.60.12~0.556.311.6~6.30.75~2.22516.3~253~11100125~10015~45250163~25055~1328001250~800160~440FunctionWiringTypical ConnectionQuotationCertification/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
