Time Current Curves TD012030ENEffective September 2015
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; 1600A/2000A - 2, 3, 4, 5, 6, 7, 8, 8, 9 2500A - 2, 2, 2, 3, 4, 5, 6, 6, 6
8 . For high fault current levels, an additional fixed instantaneous hardware override is provided to trip the breaker at 17,500A . Instantaneous tolerance is ± 20% .
9 . Maximum clearing time when using zone selective interlocking is 62ms .

8 . For high fault current levels, an additional fixed instantaneous hardware override is provided to trip the breaker at 17,500A . Instantaneous tolerance is ± 20% .
9 . Short delay I2T band has a tolerance of ±15% .
10 . Breakpoint back to FLAT response occurs at 8 x Ir for upper line of the I2T curve .
11 . Maximum clearing time when using zone selective interlocking is 62ms .
Catalog Types: RGH, RGC circuit breakers, three- and four-pole
Trip Unit Types: 35 (LSG), 36 (LSIG), 39 (ALSIG)
Ground fault delay response 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 . Trip units are suitable for functional field testing with test kit cat no: MTST230V .
4 . For LD Response and SD with Flat Responses curve, see TC01210020E .
5 . For LD Responses and SD with I2T Response curve, see TC01210021E .

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 .
3 . Total clearing times shown include the response times of the trip unit, the breaker opening, and the interruption of the current .
5 . These curves are comprehensive for the complete family of Series G R-Frame electronic breakers, including all frame sizes, ratings, and constructions . The total clearing times shown are conservative and consider the maximum response times of the trip unit, the circuit breaker opening, and the interruption of the current in 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 .
