An electronic, fault-current circuit interrupter having a predetermined, but adjustable time-current characteristic includes means (e.g. 112-118) enabling an operator to enter and adjust parameter values defining said time-current characteristics, and means (e.g. 80) providing a substantially real-time numeric display for each parameter value as it is being entered or adjusted. After entry, a continuous sequential display of the entered parameter values is provided but is temporarily interrupted during subsequent adjustment in order for said real-time display of the parameter value being adjusted to occur. A hysteresis feature is provided requiring a significant adjustment by the operator to be made before a different parameter setting is selected. <IMAGE> |
