Overview
The ARD 2F intelligent motor protector (hereinafter referred to as the 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.
The product adopts split structure, which is composed of main body, display unit, mutual
inductor and optional communication module, and can adapt to the installation of various cabinets.
Product Implementation standards:
—— GB 14048.4-2010 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.

■ 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 DC 4-20MA 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

LCD display , module size 98 × 60, opening 92 × 55 (unit : mm)
Remarks ：
（1）、 Current measuring and 2 channels of relay output DO4(97 、98) 、DO5(95 、96 、94) are
3
standard for ARD2F.
（2）、 When equipped with starting control, the protector provides no more than 2 starting relay
for the sequence control of the closing/opening of two external contactors to realize different
starting ways of motor (such as
Y-
Δ
transformation starting, positive and negative rotation control,
and self-coupling reduced-voltage starting, etc.)
（3）、 The additional function SU and Q should be chosen together.Additional function SU is
including U(voltage function) and SR(SOE event record).
（4） 、 The current specifications of 100A and below shall be the same type of current transformer.
The transformer is equipped with a secondary line of about 1m. If you need special line length,
please contact the manufacturer.The 250A and 800A current specifications use two other types of
transformers with no secondary wires.See "External Dimensions and Installation" for the
dimensions of the transformer .
（5）、The standard display cable is a network cable with a length of 1.5m. 3 meters and 5 meters
are available for optional configuration.
You
can place an order and remark the corresponding
cable length.
（6）、 For customers who do not need display modules, a batch of optional several display
modules can be used as a programmer, or the configuration software provided by the manufacturer
can be used to configure parameters through computer software.
（7）、 The temperature measurement support sensor type is PTC or NTC. 。
（8）、 After selecting the leakage function (L), each protector shall be equipped with a leakage
transformer. Please refer to the "External Dimensions and Installation" section for the dimensions
of the leakage transformer.The leakage transformer is equipped with a secondary wire of
2m ± 10cm. If other lengths are needed, please contact the manufacturer.
