Product Details

  • Microprocessor Based Static ELR, 30-3000mA

    Model No : EL-05

    Prok dv's make Static Earth Leakage Relay (ELR) with Core Balance Current Transformer ( CBCT
    / ZCT) are used to detect the leakage current in an Electrical Power System. Static Earth
    Leakage Relay (ELR) Transmits a signal to activate the trip coil of the MCCB/ACB/OCB
    CONTACTOR in the event of Earth leakage, resulting in automatic isolation of the electrical
    power system. Static earth leakage relay (ELR) and core balance current transformer (CBCT /
    ZCT) have been widely used and accepted because these have field adaptability and are


    • Frame Leakage protection for L.T. Control Panels and switch boards.
    • Earth Leakage protection for Feeders / Motors / Generators / Transformers / Mobile Operating Equipments.
    • Protection for hazardous sensitive environments like Oil Refineries/ Cement Plant/Steel Plant /Chemical Platforms/Pulp industries and General Electrical Distribution.
    • Protection for Mining & Control Engineering
    • Test & Reset Facility for testing healthiness of the relay
