1 Overview
The ARD2M motor protector (hereinafter referred to as the protector) is suitable for
low-voltage motor circuits with rated voltage up to 380V 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.
The product adopts split structure, which is composed of main body, panel, mutual inductor
and optional communication module, and can adapt to the installation of various cabinets.
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);
——JB/T 10736-2007 Low voltage motor protector.
2 Product Features
■ 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.
■ Protection functions include overload inverse time, overload definite time, grounding, starting
timeout, leakage, underload, locked-rotor, obstruction, short circuit, phase, overflow, imbalance
(current, voltage, power, less power, over voltage, under voltage, phase sequence, temperature,
external fault, tE time, running time alarm, fault alarm.
■ 8 channels programmable DI input, the default use of DC24V power supply, or external active
wet contact can be selected (see the selection table).
■ 5 programmable DO output, to meet the direct starting, star - triangle 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.
■ MODBUS_RTU and PROFIBUS DPV1 communication modules are available for selection.2
MODBUS_RTU communication channels or MODBUS_RTU+PROFIBUS DPV1
communication modules can be chosen.
■ Optional 1 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.
■ The display interface supports Chinese/English LIQUID crystal display

Remarks:
(1)Integrated current transformer is used for integrated protector with current specification of
100A and below；The split current transformer is used for the current specification of 100A and
below;
250A and 800A current specifications use another type of split current transformer. For the
external dimensions of the transformer, please refer to the "external dimensions and installation".
(2)The temperature measurement support sensor type is PTC or NTC or PT100.

(3)After the leakage function (L) is selected, each protector is equipped with a leakage transformer.
The dimensions of the leakage transformer are shown in the section "overall dimensions and
installation". Leakage transformer is equipped with 2m ±10cm secondary line as standard. If
you need other length, please contact the manufacturer.
