Product details
PROTIME’s N22-ELR senses the Earth leakage current through CBCT. These leakage current if continues, can cause insulation breakdown resulting Earth fault, which results in to loss of life or damage to equipment. PROTIME N22-ELR energises / denergises an internal relay based on Mode of operation selected by user (i.e. Normal or Fail Safe) when Leakage current goes out of the range selected on the dial. PROTIME-Earth Leakage Relays are provided with user selectable two Tripping Ranges, and also two Time delay ranges in one unit. The CBCT is connected externally with the Busbar or cable carrying load current passed through it. For more technical data please refer BROCHURE section (DS N22-ELR)
