Figure 5–56: STANDARD MOTOR CURVES
During the interval of discontinuity, the longer of the two trip times is used to reduce the chance of nui-
sance tripping during motor starts.
In some applications, the shape of the motor thermal damage curve substantially deviates from the standard. Further-
more, the characteristics of the starting (locked rotor and acceleration) and running thermal damage curves may not
correspond smoothly. In these cases, it may be necessary to use a custom curve so the motor can be started success-
fully and used to its full potential without compromising protection. For these conditions, it is recommended that the
