Notes:

1. Curve accuracy applies from -20 C to +55 C ambient. Temperatures above +88 C cause an overtemperature protection trip. For possible continuous ampere derating for ambient above 40 C,consult Rockwell Automation.

2. Application frequency is 50/60 Hertz.

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 Pick Up = 115% of ). Range is 110% - 120%.

6. Total clearing times shown include the response times of the trip unit, the breaker opening, and theinterruption of the current.

7. The Short Delay Pick Up has 9 settings/positions: 2 - 8 & 10, 14.

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

9. Breakpoint back to FLAT response occurs @ 8x for upper line of the T curve.

10. For high fault current levels an additional fixed instantaneous hardware override is provided at14x ( ).

11. For LD Response & SD with Flat Response curve, see: 40752-622

12. For LD Response & SD with T Response (this curve):

13. For Ground Fault Delay Response curve, see: 40752-623

3. There is a memory effect that can act to shorten the Long Delay. The memory effect comes into playif a current above the circuit breaker itself. A subsequent overload will cause the circuit breaker to tripin shorter time than normal. The amount of time delay reduction is inverse to the amount of time thathas elapsed since the previous overload. Approximately five minutes is required between overloads tocompletely reset memory.

1. Curve accuracy applies from -20 C to +55 C ambient. Temperatures above +88 C cause an over-temperature protection trip. For possible continuous ampere derating for ambient above 40 C, consultRockwell Automation.



5. The left portion of the curve is shown as a multiple of the Long Delay Setting.(Long Delay Pick Up = 115% of ). Range is 110% - 120%.


7. The Short Delay Pick Up has 9 settings/positions, 2 - 8 & 10, 14.

8. For high fault current levels an additional fixed instantaneous hardware override is provided at14x ( ).

9. For LD Response & SD with Flat Response (this curve): 40752-622

Curve accuracy applies from –20° C to +55° C ambient. For possible continuousampere derating for ambient above 40°C, consult Rockwell Automation.

For high fault current levels a fixed instantaneous override is provided at 4000 A.(Tolerance ±15%).

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

For ground fault time/current curve see 40752-636.

NotesElectronic trip units are suitable for functional field testing with test kit.For field testing using primary injection methods, follow NEMA publication AB-4-1991.

There is a memory effect that can act to shorten the long delay. The memory effectcomes into play if a current above the long delay pick up value exists for a time and thenis cleared by the tripping of a down stream device or the circuit breaker itself. Asubsequent overload will 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 elapsedsince the previous overload. Approximately five minutes is required between overloadsto completely reset the memory.

Notes:

1. Curve accuracy applies from -20 C to +55 C ambient. Temperatures above +85 C cause an over-temperature protection trip. For possible continuous ampere derating for ambient above 40 C, refer toRockwell Automation.



5. The left portion of the curve is shown as a multiple of the Long Delay Setting.(Long Delay Pick Up = 115% of ). Range is 110% - 120%.


7. The Short Delay Pick Up has 8 settings/positions, 2 - 8 & 10.

8. For high fault current levels an additional fixed instantaneous hardware override is provided(corresponding to SDPU position 9) at 14x ( ) and designated as 14 . Instantaneous tolerance is 20%.

9. For LD Response & SD with Flat Response (this curve): TC01207004E

10. For LD Response & SD with T Response curve, see: TC01207005E

11. For Ground Fault Delay Response curve, see: TC01207006E

° ° °°

I

3. There is a memory effect that can act to shorten the Long Delay. The memory effect comes into play if acurrent above the circuit breaker itself. A subsequent overload will cause the circuit breaker to trip inshorter time than normal. The amount of time delay reduction is inverse to the amount of time that haselapsed since the previous overload. Approximately five minutes is required between overloads tocompletely reset memory.

Notes:

1. Curve accuracy applies from -20 C to +55 C ambient. Temperatures above +85 C cause an overtemperature protection trip. For possible continuous ampere derating for ambient above 40 C, refer toRockwell Automation.



5. The left portion of the curve is shown as a multiple of the Long Delay Setting(Long Delay Pick Up = 115% of ). Range is 110% - 120%.


7. The Short Delay Pick Up has eight settings/positions: 2 - 8 & 10.

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

9. Breakpoint back to FLAT response occurs @ 8x for upper line of the T curve.

10. For high fault current levels an additional fixed instantaneous hardware override is provided(corresponding to SDPU position 9) at 14x ( ) and designated as 14 Instantaneous tolerance is

20%

Ground Fault Delay Response Notes:

1. Curve accuracy applies from -20 C to +55 C ambient. Temperatures above +85 C cause anover-temperature protection trip. For possible continuous ampere derating for ambient above40 C, refer to Rockwell Automation.

2.Application frequency is 50/60 Hertz.

3. Trip units are suitable for functional field testing with test kit style # 70C1056G52.

NotesElectronic trip units are suitable for functional field testing with test kit.For field testing using primary injection methods, follow NEMA AB4-1991 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.
