DefinitionsIn is the maximum value of continuous current for which the trip unit can be set.In is the basis (or reference) for both the Instantaneous and the Ground protection currentsettings.The value of the rating plug is printed on the Rating Plug.
Ir is the basis for both the Long Delay and the Short Delay (if provided) protection currentsettings.The value of Ir is the Long Delay Current Setting x In.

With zone interlocking on ground fault utilized and no restraining signal, the minimum timeband applies – regardless of setting.Except as noted tolerances on current levels are ± 10% of values shown in chart.The rating plug is for 50 Hz and 60 Hz, applications.All tabulated values are based on the use of a residual sensing scheme with the samerated current sensor in all phase and neutral conductors.For Testing Purposes Only: When using an external single phase current source to checklow level ground fault current settings, it is advisable to use the Auxiliary Power Module(APM). See TEST PROCEDURES in Instruction Leaflet.

Notes1) For field testing primary injection methods, follow NEMA AB4-1991 publications.2) Calibration response in short delay pickup range is the same for 1, 2, or 3 poles in series.3) There is a memory effect that can act to shorten the long delay. The memory effect
comes into play if a current above the long delay pickup value exists for a time and thenis cleared by the tripping of a downstream device or the circuit breaker itself. Asubsequent overload will cause the circuit breaker to trip in shorter time than normal.The amount of time reduction is inverse to the amount of time that has elapsed since theprevious overload. Approximately five minutes is required between overloads tocompletely reset the memory.
4) The end of the curve is determined by the interrupting rating of the circuit breaker.See above tabulation.
5) For ground fault time / current curves see SC-6345-96 (1600A), SC-6346-96 (2000A), andSC-6347-96 (2500A)
6) This curve is shown as a multiple of the Long Delay Pickup Setting, (Iprogrammed in primary value amperes via a Breaker Interface Module, or OPTIMizer,or a Remote PC (IMPACC System).
7) The Long Delay Pickup Point (indicated by a flashing LED on the product) nominally occursat 116% of the I current, with a +/- 5% tolerance. The short delay settings have conventional100%, +/- 5% as the pickup points.

Notes1) For field testing primary injection methods, follow NEMA AB4-1991 publications.2) Calibration response in short delay pickup range is the same for 1, 2, or 3 poles in series.3) There is a memory effect that can act to shorten the long delay. The memory effect
comes into play if a current above the long delay pickup value exists for a time and thenis cleared by the tripping of a downstream device or the circuit breaker itself. Asubsequent overload will cause the circuit breaker to trip in shorter time than normal.The amount of time reduction is inverse to the amount of time that has elapsed since theprevious overload.

Notes1) For field testing primary injection methods, follow NEMA AB4-1991 publications.2) Calibration response in short delay pickup range is the same for 1, 2, or 3 poles in series.3) There is a memory effect that can act to shorten the long delay. The memory effect
comes into play if a current above the long delay pickup value exists for a time and thenis cleared by the tripping of a downstream device or the circuit breaker itself. Asubsequent overload will cause the circuit breaker to trip in shorter time than normal.The amount of time reduction is inverse to the amount of time that has elapsed since theprevious overload. Approximately five minutes is required between overloads tocompletely reset the memory.
4) The end of the curve is determined by the interrupting rating of the circuit breaker.See above tabulation.
5) For ground fault time / current curves see SC-6345-96 (1600A), SC-6346-96 (2000A), andSC-6347-96 (2500A)
6) The instantaneous settings have conventional 100%, +/- 10% as the pickup points.
