Manual Reset Type


Eaton's Cooper Power series S.T.A.R. Manual Reset (MR) faulted circuit indicators are designed to quickly and easily locate faulted sections of cable on distribution systems. These faulted circuit indicators (FCIs) can be installed on pad-mounted distribution transformers, sector cabinets, switchgear, and overhead distribution lines. Manual Reset FCIs provide a reliable means of fault location and isolation. In addition, they eliminate fault chasing methods which are costly and time consuming, and very stressful on system components exposed to the fault currents. Manual Reset faulted circuit indicators are designed to operate on overhead uninsulated, unshielded cable and unshielded insulated cable (such as tree wire), as well as concentric neutral and other cable, in underground, pad-mounted and vault applications.

Design Features

  • A low pass filter, a standard feature on the MR FCI, will prevent the S.T.A.R. faulted circuit indicator from tripping on high frequency transients like those caused by capacitive discharges.
  • In addition, the S.T.A.R. faulted circuit indicator is equipped with temperature compensation circuitry to assure the accurate and reliable performance over the entire specified temperature range.
  • The quick response time of the S.T.A.R. manual reset faulted circuit indicator provides easy coordination with current-limiting fuses and other protective devices.
  • This unique combination of standard features makes the S.T.A.R. faulted circuit indicator extremely reliable.
