Table 5. Curve notes

1. These curves apply for 50Hz and 60Hz applications

2. The maximum voltage rating for the frame style is stated in Table 4.

3. These curves are comprehensive for Power Defense style circuit breakers including frame sizes, ratings and constructions stated.

4. The total clearing times shown include the response time for the trip unit, the breaker opening and the interruption of the current. The bottom of the time band is the minimum commit to trip time.

5. The end of the curve is determined by the application or the interrupting rating of the circuit breaker.

8. All electronic trip units have an over temperature protection feature that will trip the breaker when the internal temperature of the ETU is over 105ºC

9 All time current data based on 3 phase testing.

Notes: 1. Long delay pickup is 110% of the Ir setting with

±5% tolerance. Ir is set from min to max at steps of 10 A.

2. Long delay time settings adjustable from 0.5s - 14s at steps of 0.1s with +0%/-30% toler-ance.

3. If thermal memory is enabled, trip times may be shorter than indicated in this curve.

4. Short delay pickup settings adjustable from 1.5x - 12x at steps of 0.1x with ±5% tolerance.

5. Short delay time settings adjustable from 0.050s – 0.500s at steps of 0.010s with tolerances as follows: time delay settings 0.500s to 0.200s have tolerances of +0/-20%, time delay settings between 0.190s to 0.160s have tolerances of +0/-30%, and time delay settings between 0.150s to 0.100s have tolerances of +0/-40% and time delay settings between 0.090s to 0.050s have tolerances of +20%/-50%.

6. If the long delay time is projected to be faster than the short delay time, the long delay trip time will go no faster than the short delay time value.

7. With ZSI enabled and no auxiliary power, tripping times for 3-phase faults will be a maximum of 60ms for 60Hz and 63ms for 50Hz.

Notes: 1. Long delay pickup is 110% of the Ir set-

ting with ±5% tolerance.2. Long delay time settings as shown have

+0% /-30% tolerance.3. If thermal memory is enabled, trip times

may be shorter than indicated in this curve.

4. Short delay pickup settings as shown have ±5% tolerance.

5. Short delay I2t slope time settings are as follows: I2t slope time delay setting 0.300s has a tolerance of +0/-30%, time delay setting 0.150s has a tolerance of +0/-40% and time delay setting 0.067s has a tolerance of +0/-50%. After approximately 8x the I2t slope will go flat and those times have tolerances as follows: time delay setting 0.300s has a tolerance of +0/-20%, time delay setting 0.150s has a tolerance of +0/-40% and time delay setting 0.067s has a tolerance of +0/-50%.
