Microprocessor Based Static ELR, 300mA-3000mA

Model No : EL-03 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. Conventional over current and short circuit protection device are not designed detect earth leakage currents. Prok dv’s make Earth Leakage Relay (ELR) with Core Balance Current Transformer ( CBCT / ZCT) are used to detect the leakage current in an Electrical Power System. 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. Earth leakage relay (ELR) and core balance current transformer (CBCT / ZCT) have been widely used and accepted because these have field adaptability and are economic. More Details
