Claim Text:
1. A circuit breaker comprising a series of inputs designed to be connected to a first microcontroller configured to measure characteristics of an electric current of a power supply line to detect an electric fault of the power supply line, a second microcontroller supplied by said power supply line and presenting a first electricity consumption value, the second micro-controller being configured to analyse data coming from the first microcontroller in order to detect an electric fault of the power supply line, a third microcontroller supplied by said power supply line and connected so as to receive data from the first and second micro-controllers, the third microcontroller being configured to indicate a cause of tripping of the circuit breaker, the third microcontroller presenting a second electricity consumption lower than the first electricity consumption value, a back-up power supply source configured to supply the third microcontroller in case of unavailability of the power supply line.
