When adjustable rating plugs are used, short delay pickup settingstrack the selected position of the adjustable rating plug. Forexample, with an adjustable 250 amp rating plug set at 50% andthe short delay pickup set at 4X, the short delay pickup is250 X 50% X 4 - 500 amps.
The threshold point changes with the ampere value of the ratingplug.
