Product Details

  • Microprocessor based Din Mount 30-96A

    Model No : PDMMPR-04


    The Microcontroller Based Motor Protection Relay does not require external Current Transformer (CT) for its operation for within the bandwidth of Im ranges. The three phase R, Y and B cables are made to pass through the CT hole which is in the relay. The built in CT’s takes care of stepping down of the Currents to the required level. The stepped down three phase Currents are continuously monitored by the relay to detect any abnormal behavior of the Motor and to make tripping decision.
