Prok dvs Earth Leakage Relays
Product Code : 06
Product Description

Prok dv's make Earth Leakage Relays (ELR) with Core Balance Current Transformer (CBCT) 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.
