Overview
The ARD2F 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, 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.

Remarks:
(1).Current measuring and 2 channels of relay output DO4(97.98).DO5(94.96.95) are 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.
