Note:Time/Current characteristic curves for Series C R-frame circuit breakers--voltages shown in curve headings aremaximum at which the breaker may be applied . Interrupting capacity of inidvidual breaker is tabulated on each curve .

Note:The following curves are UL489 Listed for use in North America .The following circuit breakers are derived from Eaton, Westinghouse, or Cutler-Hammer history .

Time Current Curves are engineering reference documents for application and coordination purposes only. For field testing molded case circuit breakers, refer to NEMA AB 4 guidelines.

notes:

1 With zone interlocking on ground fault utilized and no restraining signal, the minimum time band GDM applies – regardless of setting .

2 Except as noted tolerances on current levels are ± 10% of values shown in chart .

3 The rating plug is for 50 Hz and 60 Hz, applications .

4 All tabulated values are based on the use of a residual sensing scheme with the same rated current sensor in all phase and neutral conductors .

5 For Testing Purposes Only: When using an external single phase current source to check low level ground fault current settings, it is advisable to use the Auxiliary Power Module (APM) . See TEST PROCEDURES in Instruction Leaflet .

Response: LonG DeLaY I2t, SHoRt DeLaY I2t

notes:

1 . For field testing primary injection methods, follow NEMA AB4 guidelines .

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 then is cleared by the tripping of a downstream device or the circuit breaker itself . A subsequent 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 the previous overload . Approximately five minutes is required between overloads to completely reset the memory .

4 . The end of the curve is determined by the interrupting rating of the circuit breaker . See above tabulation .

5 . This curve is shown as a multiple of the Long Delay Pickup Setting, (Ir) . This Ir setting is programmed in primary value amperes via a Breaker Interface Module, or OPTIMizer, or a Remote PC (IMPACC System) .

6 . The Long Delay Pickup Point (indicated by a flashing LED on the product) nominally occurs above 115% of the Ir current, with a +/- 5% tolerance . The short delay settings have conventional 100%, +/- 5% as the pickup points .

7 . For additional curve tolerances contact Eaton .

8 . Total clearing times shown include the response times of the trip unit, the breaker opening, and the quenching of the arcing current .

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 Pick-up Setting, (I ). This I setting isprogrammed in primary value amperes via a Breaker Interface Module, or OPTIMizer,or a Remote PC (IMPACC System).

7) The Long Delay Pick-up Point (indicated by a flashing LED on the product) nominally occurs

8) For additional curve tolerances contact Cutler-Hammer.9) Total clearing times shown include the response times of the trip unit, the breaker opening, and the extinction of the arcing current.

at 116% of the I current, with a +/- 5% tolerance. The short delay settings have conventional100%, +/- 5% as the pickup points.

6) This curve is shown as a multiple of the Long Delay Pick-up Setting, (I ). This I setting isprogrammed in primary value amperes via a Breaker Interface Module, or OPTIMizer,or a Remote PC (IMPACC System).

7) The Long Delay Pick-up 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.
