Intelligent Motor Protector, ARD3M

The ARD3M intelligent motor protector is suitable for 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 logic programmable function, can meet a variety of control methods. Different communication modules can be selected to meet the needs of field communication.

Product Implementation standards

GB 14048.4-2020 Low-voltage switchgear and control gear
Part 4-1: Contactors and motor starters
Electromechanical contactors and motor starters (including motor protectors);
JBT 10736-2007 Low voltage motor protector

Features

The auxiliary power type is optional. The AC220V power module supports the power range of AC85-265V/DC100-300V and the AC380V power module supports the power range of AC/DC100-415V.
Support fundamental and full-wave power parameter measurement (U, I, P, Q, S, PF, F, EP, EQ), voltage and current imbalance degree, voltage and current positive sequence, negative sequence, zero sequence component, three-phase voltage phase angle, residual current, voltage and current 2-63 sub-harmonic measurement, sub-harmonic inclusion rate and total harmonic distortion rate.
Protection functions include overload inverse time, overload definite time, grounding, starting a timeout, leakage, under load, locked-rotor, obstruction, short circuit, phase, overflow, imbalance (current, voltage, power, less power, overvoltage, undervoltage, phase sequence, temperature, time, external fault, tE starting number, running time, alarm, fault alarm.
10 channels programmable DI input, the default use of DC24V power supply, or external active wet contact can be selected (see the selection table).
6 channels programmable DO output, to meet the direct starting, Y- △ starting, auto-transformer starting, and other starting modes, can be through the communication bus to achieve the master station to the motor remote control "start/stop".
Optional anti-shaking function: support immediate restart of shaking power and restart of voltage loss.
2 MODBUS_RTU communication channels are standard, and PROFIBUS DPV1, Ethernet and Profinet communication modules are available for selection.
Optional 2 channels DC4-20mA analog output interface, connected with DCS system, can realize the monitoring of field equipment.
With fault record, start record, stop record, DI displacement record, restart record and other records of various events, you can view a number of motor operation and maintenance information, and can record the motor operation record for 1-5 hours at the same time.
The display interface supports Chinese/English liquid crystal display
It supports exporting waveform record and event record data on USB flash disk, and can open exporting event record file with EXCEL.
WIFI function can be added when color LCD is optional, and relevant data of motor protector can be viewed and set by connecting the WIFI via mobile phone or computer.
