Abstract: The present invention relates to a display device for a digital trip device associated with a current breaking device. The trip device comprises apparatus for entering operating parameters and apparatus for measuring the current in the breaking device, these two apparatuses being coupled with a first microprocessor comprising memory areas in which the parameters and measurement data are entered. The display device is of the portable type, able to be coupled temporarily with the trip device, and comprises: an alphanumerical display, a second microprocessor comprising memory areas, apparatus associable with complementary apparatus in the trip device to transfer the contents of the memory areas of the trip device to the memory areas of the display device, these contents then being able to be displayed selectively by the reader during or after the temporary coupling.
