Product Description
The relay senses the Earth leakage current for any equipments like L. T. Panels, Switch boards, Generators, Transformers, Motors etc. These Leakage current if continues can cause insulation breakdown resulting Earth fault, which results in to loss of life or damage to equipment. The PROTIME Earth leakage relay senses leakage current through CBCT & energies relay when current goes out of the range selected on the dip switches. The Relays are provided with user settable (0-10 Sec) time delay. The CBCT is connected externally with the Busbar or cable carrying load current passed through it. The Relay has facility to show fault current indication on pressing STATUS Button. Thus this feature helps user to identify the point of fault & find out the value of fault current passing through it.
