An electronic protection device for a LV electric line including one or more conductors (P, N), comprising: - one or more pairs of electric contacts electrically connectable with corresponding conductors of said electric line and adapted to be mutually coupled or decoupled, said electric contacts being coupled when said protection device is in a closed state and being decoupled when said protection device is in a tripped state or open state; - a control unit comprising a controller including data processing resources, said controller being capable of testing the operating conditions of said electronic protection device; - a signalling arrangement including one or more signalling devices driven by said controller; wherein said signalling arrangement comprises a first signalling device adapted to provide light signals (L1, L2, L3) indicative of the operating conditions for said electronic protection device, when said electronic protection device is in a closed state, wherein said controller drives said first signalling device in a non-alarm state, if said controller determines normal operating conditions for said electronic protection device, said first signalling device providing a first light signal indicative of normal operating conditions for said electronic protection device, when said first signalling device is driven in said non-alarm state, wherein said controller drives said first signalling device in a first alarm state, if said controller determines first recoverable fault conditions for said electronic protection device, characterised in that said controller continues to test the operating conditions of said electronic protection device after having driven said first signalling device in said first alarm state and drives said first signalling device from said first alarm state to said non-alarm state, if said controller determines normal operating conditions for said electronic protection device again. - one or more pairs of electric contacts electrically connectable with corresponding conductors of said electric line and adapted to be mutually coupled or decoupled, said electric contacts being coupled when said protection device is in a closed state and being decoupled when said protection device is in a tripped state or open state; - a control unit comprising a controller including data processing resources, said controller being capable of testing the operating conditions of said electronic protection device; - a signalling arrangement including one or more signalling devices driven by said controller; wherein said signalling arrangement comprises a first signalling device adapted to provide light signals (L1, L2, L3) indicative of the operating conditions for said electronic protection device, when said electronic protection device is in a closed state, wherein said controller drives said first signalling device in a non-alarm state, if said controller determines normal operating conditions for said electronic protection device, said first signalling device providing a first light signal indicative of normal operating conditions for said electronic protection device, when said first signalling device is driven in said non-alarm state, wherein said controller drives said first signalling device in a first alarm state, if said controller determines first recoverable fault conditions for said electronic protection device, characterised in that said controller continues to test the operating conditions of said electronic protection device after having driven said first signalling device in said first alarm state and drives said first signalling device from said first alarm state to said non-alarm state, if said controller determines normal operating conditions for said electronic protection device again.
