Our faulted circuit indicators are designed to minimize restoration time by providing a visual indication of the affected circuit, reducing the costs of fault locating, crew and equipment time. Edison Controls line-powered faulted circuit indicators are a proven design used by IOU’s, Co-Ops, Munis, and public utilities everywhere. Hundreds of thousands of units are in service worldwide. When a series of EC FCls are installed on a distribution network, they work like this:

Edison Controls Faulted Circuit Indicators are line powered; no routine maintenance is required. Permanently installed, they will operate reliably for twenty years or more. All Edison Controls faulted circuit indicators are individually routine tested before shipment to meet stringent assembly and performance specifications. Overload protection, mechanical, and electrical integrity is built in.
