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, 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.
