Abstract
The communication circuit of the self-powered trip device is disabled by the trip device microprocessor when the values of the measured currents are lower than preset values. The microprocessor sends a bit, called the power saving bit, before disabling the communication circuit so as to inform a monitoring device connected to the trip device of the cause of the interruption of transmission from the trip device.
