Abstract
A graphical representation of the current/time trip characteristic displayed on the operator's panel of an electronic trip unit for a circuit interrupter, has different indicia, such as different colors, identifying the representation of independent trip functions from those of dependent trip functions, thereby making the operator aware that adjustment of one of the dependent trip functions will also affect an adjustment of the other dependent portions of the current/time trip characteristic.
