ARD3M Motor Protection ControllerThe 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 logic programmable function,
can meet a variety of control methods.Different communication
modules can be selected to meet the needs of fieldParameters
