Digitrip 310+ Circuit Breaker Time/Current Curves (Phase Current)

Series G N-Frame Circuit Breakers

Long Delay Response and Short Delay with Flat Response and Override

Catalog Types: NGS, NGH, NGC, NGU, GNS, GNH, GNC, and GNU circuit breakers, three- and four-pole

Trip Unit Type: 32 (LSI), 36 (LSIG), 38 (ALSI), 39 (ALSIG)

Notes:

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

2. Application frequency is 50/60 Hz.

3. There is a memory effect that can act to shorten the Long Delay. If the breaker trips on a Long Delay overload and is quickly reset, the memory capacitor will still have charge and a subsequent overload will cause the breaker to trip in a 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 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 Pickup has nine settings/positions, 2–8; the last two switch positions are the same: 9X.

8. For high fault current levels, an additional fixed instantaneous hardware override is provided to trip the breaker at 14400A. Instantaneous tolerance is +/- 20%. For the 1600A frame only, if Ir is set to the maximum (position H) and SDPU is set to the maximum (position 9), then the SDPU setting and the Instantaneous Override are set to the same value. The Instantaneous Override has precedence over SDPU. Therefore, the breaker will trip on Instantaneous Override.

Figure 3. Digitrip 310+ Long Delay Response and Short delay with I2T Response Curve (LS, LSG) - Curve Number TC01210011E, March 2012






Notes:

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


3 . There is a memory effect that can act to shorten the Long Delay . If the breaker trips on a Long Delay overload and is quickly reset, the memory capacitor will still have charge and a subsequent overload will cause the breaker to trip in a 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 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% .


7 . The Short Delay Pickup has nine settings/positions, 2–8; the last two switch positions are the same: 9X .

8 . Short Delay I2 T band has a tolerance of +15% .

9 . Breakpoint back to FLAT response occurs @ 8x Ir for upper line of the I2 T curve .

10 . For high fault current levels, an additional fixed instantaneous hardware override is provided to trip the breaker at 14400A . Instantaneous tolerance is +/- 20% . For the 1600A frame only, if Ir is set to the maximum (position H) and SDPU is set to the maximum (position 9), then the SDPU setting and the Instantaneous Override are set to the same value . The Instantaneous Override has precedence over SDPU . Therefore, the breaker will trip on Instantaneous Override .

11 . Maximum clearing time when using zone selective interlocking is 62ms .

Notes:

1 . The maintenance mode feature must be ENABLED for these curves to apply . The LED indicator is blue when in maintenance mode .

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


4 . Available pickup settings ( x In) (tolerance is ±15%) 2 .5, 4, 6, 7, 8, 10 .

5 . The Maintenance Mode consists of the two lowest settings of the INST switch: 2 .5x and 4 .0x . 6 . The Remote Maintenance Mode is enabled by applying 24 VDC to the two wire cable that exists the left side of the breaker . The wires are color coded as follows: Yellow = +24 V and Black = common ground . A blue colored LED, on the left side of the breaker is the Maintenance Mode section of the trip unit, will light . The lighted blue LED indicates that the lowest setting of the Maintenance Mode is enabled . This setting corresponds to 2 .5x of In . Turning the adjustable switch on the trip unit has no affect on either the Maintenance Mode or the INST Mode settings while the blue LED is lit . In addition to the blue colored LED, a relay contact (C, NO) is available . The wires for this contact exit the left hand side of the breaker and are color coded as follows: Blue = C, and Red = NO .

7 . Contact Eaton for additional information .

1. For field testing primary injection methods, follow NEMA� AB4 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 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 Interrupting ��rating table above.

5. The Long Delay and Short Delay Pickup tolerances are � 6. For additional curve tolerances, contact Eaton.

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

Notes:

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

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 publication AB-4 .

1 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 pick up 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 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 .

2 For high fault current levels a fixed instantaneous override is provided at 14000A (Tolerance ±15%) .

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

4 Not UL/CSA Listed .

5 Long Delay Pickup is 115% of In, +/- 5% .

Figure 15. Long Delay I2T, Short Delay I2T - Curver Number SC-6331-96, October 2006


Series C N - Frame Circuit Breakers

Equipped With Digitrip Optim Trip Units

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 .


5 This curve is shown as a multiple of the Long Delay Pick-up 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 Pick-up 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 .
