  • Microprocessor based Din Mount 1-10A

    Model No : PDMMPR-01

    Prok dv’s make Microcontroller Based Motor Protection Relay PD-MMPR-303 uses the state-of-the-art Microcontroller based measurement techniques for providing protection for Motors up-to 75HP. The comprehensive protection features of the relay make it ideal for Motor protection. The heart of the relay is microcontroller based reliable hardware with special algorithms to calculate the tripping time. The relay continuously monitors the Three Phase Currents to build the thermal replica of the Motor. This thermal replica is used to protect the Motor against Thermal over Loads.

  • Microprocessor based Din Mount 10-32A

    Model No : PDMMPR-02

The comprehensive protection features of the relay make it ideal for Motor protection. The heart of the relay is microcontroller based reliable hardware with special algorithms to calculate the tripping time. The relay continuously monitors the Three Phase Currents to build the thermal replica of the Motor. This thermal replica is used to protect the Motor against Thermal over Loads.
    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.

  • Microprocessor based Din Mount 20-64A

    Model No : PDMMPR-03

    Prok dv’s make Microcontroller Based Motor Protection Relay continuously monitoring Real Time Motor Current of all the Three Phases. When the Motor Current exceeds the set value Im, the relay issues a trip command after the calculated time elapse (Based on selection of trip Class). The relay visually indicating the fault trip status by means of LED’s.
    Two Set of potential free output changeover contact is provided in the relay C& NC and C& NO for trip circuit .The relay continuously monitors the Currents and using this data it builds Thermal replica of the Motor and monitoring the Thermal status of the Motor. This information is used to protect the Motor against Thermal over Loading.

  • 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.
