Note:Time/Current characteristic curves for Series C M-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.

Breaker Type 240V 480V 600V

Notes:

1 Curve accuracy applies from 20C to +55C ambient . For possible continuous ampere

derating for ambient above 40C, refer to Eaton . Temperatures above +88C cause an

over-temperature protection trip.

2 Application frequency is 50/60 Hertz.

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 right portion of the curve is determined by the interrupting rating of the circuit breaker.

5 The left portion of the curve is shown as a multiple of the Long Delay Setting.

(Long Delay Pickup = 115% of Ir). Range is 110%120%.

6 Total clearing times shown include the response times of the trip unit, the breaker opening,

and the interruption of the current.

7 The Short Delay Pick Up has 7 settings/positions, 28 Ir

8 Short Delay I2T band has a tolerance of 15%.

9 Breakpoint back to FLAT response occurs at 8x IRfor upper line of the I2T curve.

10 For high fault current levels, an additional fixed instantaneous hardware override is providedat 6800A (Tolerance 15%).

Notes:

1 The Maintenance Mode feature must be ENABLED via application of

24 Vdc for these curves to apply. The blue LED is lit when in Maintenance Mode.

2 The end of the curve is determined by the interrupting rating of the circuit breaker.

3 Total clearing times shown include the response times of the trip unit,

the breaker opening, and the interruption of the current.

4 Nominal Values (Pickup) (Tolerance is 15%) 2.5 x In.

5 The total clearing times shown are conservative and consider the maximum response

time of the trip unit, the circuit breaker opening, and the interruption of the current in the worst case conditions such as: maximum rated voltages, single-phase interruption,

and minimum power factor. Faster clearing times are possible depending on the specific

system conditions.

Notes:

Digitrip RMS 310 trip units are suitable for functional field testing with test kit Cat. No. STK2.For field testing using primary injection methods, follow NEMA AB4 publications.

Calibration response in short delay pick-up range is same for 1, 2 or 3 poles in series.

There is a memory effect that can act to shorten the long delay. The memory effect comesinto play if a current above the long delay pick-up value exists for a time and then is clearedby the tripping of a downstream device or the circuit breaker itself. A subsequent overloadwill cause the circuit breaker to trip in shorter time than normal. The amount of time delay

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.

1 Curve accuracy applies from 20C to +55C ambient. For possible continuous ampere derating for ambient above 40C, refer to Eaton.

2 For high fault current levels a fixed instantaneous override is provided at 6800A. (Tolerance 15%).

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

4 Long delay pickup is 115% of In, +/- 15%.

Notes:

Digitrip RMS 310 trip units are suitable for functional field testing with test kit Cat. No. STK2.For field testing using primary injection methods, follow NEMA AB4 publications.

Calibration response in short delay pick-up range is same for 1, 2 or 3 poles in series.

There is a memory effect that can act to shorten the long delay. The memory effect comesinto play if a current above the long delay pick-up value exists for a time and then is clearedby the tripping of a downstream device or the circuit breaker itself. A subsequent overloadwill cause the circuit breaker to trip in shorter time than normal. The amount of time delayreduction 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.

1 Curve accuracy applies from 20C to +55C ambient. For possible continuous ampere derating for ambient above 40C, refer to Eaton.

2 For high fault current levels a fixed instantaneous override is provided at 6800A. (Tolerance 15%).

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

4 Long delay pickup is 115% of In, +/- 5%.
