S.T.A.R.™ Test Point Reset Type Faulted Circuit Indicators
Reliable Fault Detection in a Small, Easily Applied Package
Description:
Cooper Power Systems’ S.T.A.R. Test Point Reset (TPR) faulted circuit indicators (FCIs) can be used on
all 200 A and 600 A connectors having a voltage test point. Load levels do not effect the reset circuit. The
unit automatically resets to the normal position when circuit voltage is restored.
The remote FISHEYE™ display, with a highly reflective orange target, provides enhanced 180 degree
visibility. This unique display fits a standard remote indicator window used on padmounted
transformers. A smaller remote display is also available. Installation of the small remote display requires
only a single opening in the equipment cabinet. Without the remote display, a highly visible integral orange
fluorescent target is standard. All displays are black under normal conditions.
The selection of a TPR faulted circuit indicator has never been easier! For conventional indicators, trip
ratings are selected based on elbow voltage class, load current and minimum fault current levels. Trip
rating selection for S.T.A.R. faulted circuit indicators has been reduced to two simple choices. For a 200 A
URD circuit, select a “LO” trip rating. For a 600 A distribution system, select a “HI” trip rating. This approach
to trip selection means that one indicator fits all 15, 25 and 35 kV elbows.
With this simplified approach to rating selection:
■ Ordering is easier and faster.
■ Inventory is reduced, eliminating the need to stock multiple designs.
■ Pre-installation load surveys are not needed.
■ FCI changeouts are not necessary as systems grow.
■ Misapplication due to trip selection errors is eliminated.
For SCADA applications, auxiliary contacts (as shown above) can be added. The magnetic latching circuit
that operates the auxiliary contact ensures reliable indication.
Design Features:
These design features are standard on every S.T.A.R. faulted circuit indicator:
■ Inrush Restraint: Eliminates false tripping due to recloser operations
■ Low Pass Filter: Prevents tripping on high frequency transients
■ Temperature Compensation Circuitry: Assures accurate, reliable performance over a wide
temperature range
■ Reliable Open Core CT Design: Eliminates tripping due to adjacent magnetic fields
■ Quick Response Time: Coordinates with all current-limiting fuses
■ Tough, Durable Construction: Corrosion-proof, damage-resistant, display status cannot
mechanically change
■ Exceeds ANSI®/IEEE Standard 495-1986™
■ Quick and Easy Installation: Only one hot stick is required

Because we’ve incorporated so many “custom” features into our standard design, we’ve drastically reduced
the part numbers. This makes ordering easier and delivery faster. Use the diagram below to select the
S.T.A.R. Test Point Reset Type faulted circuit indicator for your application. Contact your local Cooper Power
Systems sales engineer for catalog section 320-40 and additional information.
