  • Microprocessor Based Digital ELR, 300mA-12A

    Model No : MPEL-01

    Earth Leakage Current give rise to generation of heat and result in progressive failure of
    insulation, which leads to earth faults sparking flashovers, deterioration of earthing and finally
    results into catastrophic fires which destroys costly equipments, gadgets and precious lives.
    It is therefore essential to detect earth leakage current well before they cross the threshold
    limits and isolate the circuit in the event of leakages.

    Prok dv's make Digital microprocessor/microcontroller based Earth Leakage Relays (ELR) with
    Core Balance Current Transformer (CBCT / ZCT) are used to detect leakage currents in
    electrical power systems. 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 load. ELR have been widely used and accepted because of field adaptability and
    are economic.
