Abstract
The electronic trip device comprises a processing unit comprising protection means, and an initialization device of said processing unit. The initialization device comprises means for initialization after an interruption comprising at least one storage register connected to the protection means to store a value of at least one quantity of a protection function and to supply a value of said at least one quantity when initialization of the processing unit is performed. A back-up power supply circuit supplies the storage register, and means for monitoring the back-up power supply circuit delete the register values when a voltage of the back-up power supply circuit drops below a preset threshold.
