Motor Circuit Protector ARD2F

Motor Circuit Protector ARD2F

ARD2F smart motor protectors can protect motors from many faults during motor running and display the running state clearly and intuitively through LCD. The protector has an RS485 remote communication interface and DC4-20mA analog output, which makes it convenient to form a network system together with control machines like PLC and PC.

  • RS485 Communication Modbus-RTU
  • LCD Display for U, I, P, Q, etc
  • AC380/660V, Rated current up to 800A
