Abstract

Selector switches placed on the front panel of the trip device enable first protection parameters to be set. The trip device comprises communication means enabling second protection parameters to be set by remote setting. The trip device compares each first parameter with the corresponding second parameter and determines third protection parameters representative of the lower of the first and second parameters. The third protection parameters are taken into account by the trip device for protection against overloads and short-circuits and are displayed on the front panel of the trip device when setting of the parameters takes place or on request.
