If Thermal Memory is enabled, trip times may be shorterthan indicated in this curve.4. Short Delay pickup settings adjustable from 1.5x - 12x atsteps of 0.1x with 5% tolerance.5. Short delay time settings adjustable from 0.050s – 0.500sat steps of 0.010s with tolerances as follows: time delaysettings 0.500s to 0.200s have tolerances of 0/-20%, timedelay settings between 0.190s to 0.160s have tolerances of 0/-30%, and time delay settings below 0.150s to 0.100shave tolerances of 0/-40% and time delay settings between0.090s to 0.050s have tolerances of 0/-50%.6. If the Long Delay time is projected to be faster than the ShortDelay time, the Long Delay trip time will go no faster thanthe Short Delay time value.7.

Figure 5 (below) shows a B Trip Curve overlaid onto the chart. The three major components of the Trip Curve are: 1. Thermal Trip Curve. This is the trip curve for the bi-metallic strip, which is designed for slower overcurrents to allow for in rush/startup, as described above. 2. Magnetic Trip Curve. This is the trip curve for the coil or solenoid.

Koch middle-one fifth curve (Fig. 8a) and Koch middle one-sixth curve (Fig. 9a) has dimensions 1.113 and 1.086 respectively that are smaller than the conventional Koch curve.

The efficiency curve shows the efficiency of the pump. The efficiency curve is an average curve of all the pump types shown in the chart. The efficiency of pumps with reduced-diameter impellers is approx. 2 % lower than the efficiency curve shown in the chart. Pump type, number of poles and frequency. QH curve

Creating a new design curve from brushing over a French curve is simply a matter of generating a sub-curve [10] from the formula-tion of the digital French curve. Editing design curves using French curves is based on the premise that the section of the design curve being edited has the same general shape and position in space as the
