The invention relates to an electric installation arrangement (1) for the operation of an electric consumer network (2), having at least one first sw itch (3) for disconnecting at least one first consumer (4) and/or one partia l network (30) from the consumer network (2), at least one first sensor (5) for detecting at least one first physical variable that is induced, or can b e influenced, by the consumer network (2), and at least one first tripping u nit (6), which switches off the first switch (3) within a first tripping tim e if a first tripping threshold value that can be predetermined is exceeded by a first measured variable proportional to the first variable, and thereby disconnects the consumer (4) and/or the partial network (30) from the consu mer network (2). In order to prevent unnecessary disconnections from the net work and guarantee high network availability, according to the invention the electric installation arrangement (1) has at least one first regulating and control unit (7) for the definable and automatic adjustment of the first tr ipping threshold value and/or of the first tripping time as a function of at least one control parameter.
