Table 6. Curve notes
1. These curves apply for 50Hz and 60Hz applications
2. The maximum voltage rating for the frame style is stated in Table 5.
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.
6. Thermal Magnetic trip unit calibration based on 40°C ambient, cold start. Tested with 4 feet of rated wire (75°C) per terminal. Tested in open air with current in all poles.
7. Thermal Magnetic trip unit instantaneous calibration based on single pole testing.
8 All time current data for PXR is based on 3 phase testing. For ground testing refer to Instruction Leaflet IL012125EN..

Notes:1. Ground pickup settings adjustable from 0.2x - 1.0x
at steps of 0.010x for residual sensing with a toler-ance of± 10%.
2. Ground time delay settings adjustable from 0.100s - 1.00s at steps of 0.010s with tolerances as follows: time delay settings 1.00s 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 +20/-40%.
3. If thermal memory is enabled, trip times may be shorter than indicated in this curve.
4. With ZSI enabled, tripping times for 3-phase faults, no aux. power will be a maximum of 60ms for 60Hz and 63ms for 50Hz.

Notes:1. Ground pickup settings adjustable from 0.2x - 1.0x
at steps of 0.01x are for residual sensing with a tolerance of ± 10%.
2. Ground I2t slope time settings are adjustable from 0.067s - 0.300s at steps of 0.010s with tolerances as follows: I2t slope time delay settings 0.300s to 0.200s have tolerances of +0/-30%, 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 0.067s have tolerances of +20%/-50%. After approximately 1x the I2t slope will go flat and those times have tolerances as follows: time delay settings 0.300s 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%.
3. If thermal memory is enabled, trip times may be shorter than indicated in this curve.
4. With ZSI enabled, tripping times for 3-phase faults, no aux. power will be a maximum of 60ms for 60Hz and 63ms for 50Hz.

Notes: 1. Long delay pickup is 110% of the Ir setting with ±5% toler-
ance.2. Long delay time setting has +0%/-30% tolerance. It is fixed
at a 10s time band.3. Instantaneous pickup settings have ±10% tolerance.4. Short delay pickup settings as shown have ±5% toler-
ance.5. If thermal memory is enabled, trip times may be shorter than
indicated in this curve.6. Setting J in the table is the default value but can be pro-
grammed from a minimum of 2x to a maximum of 10x in steps 0.5x and a time delay of 50ms to 300ms in steps of 50ms using the Power Xpert Protection Manager software (PXPM).
7. When Profile K is selected, PXR 10 LI style curve should be used.

tolerance.3. Instantaneous pickup settings have ±10%
tolerance.4. For high fault current levels a fixed instantaneous
override is provided at 2100A and has a ±15% tolerance.
5. If thermal memory is enabled, trip times may be shorter than indicated in this curve.
