Product Description

ARD3M Motor Protector Relay with Profibus, Profinet, Ethernet, Modbus

The ARD3M 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 a logic programmable function, and 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 controlgear
    -- Part 4-1: Contactors and motor starters
       -- Electromechanical contactors and motor starters (including motor protectors); 

--JBT 10736-2007 Low voltage motor protector.
