Microprocessor Based Digital ELR,30mA-3A

Model No : DMPEL-02 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. More Details
