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.

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 set-tings 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 toler-ances of +0/-50%.
3. If thermal memory is enabled, trip times may be shorter than indicated in this curve.
4. 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.
