Product Details

  • Numerical Draw-out 2 Over Current & 1 Earth Fault

    Model No : PNA422-D


    Relay has modbus protocol with RS 485 port with baud rate 9600bps. Another
    model is established for special applications with baud rate115kbps.Relay records 99 faults
    with date and time. Relay rating (In) is field selectable- either 1A/5A.The output relays are
    configurable Configurable options for enabling & disabling of high-set in both Phase &
    earth.
