  • Microprocessor Based Static ELR, 30mA-300mA

    Model No : EL-02

    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


    • Consistent reliability with accuracy.
    • Fixed or variable current sensitivity by Dip Switch selection
    • LED’s for visual indication of fault.
    • High Barrier connector at rear for easy termination and safety standards.
    • Tamper proof polycarbonate cover in the front.
    • Test & Reset Facility for testing healthiness of the relay
