Abstract: An electronic protection device (1) for a LV electric line (100) including at least a phase conductor (P) and a neutral conductor (N), comprising: —input terminals (IN) and output terminals (OUT), at which said electronic protection device is electrically connected respectively with an electric power source (SC) and with an electric load (LD) through said phase and neutral conductors (P, N); —a control unit (3) comprising a controller (31) including data processing resources; —one or more pairs of main contacts (2) electrically connected with corresponding one or more input and output terminals (IN, OUT) and adapted to be mutually coupled or separated; —one or more pairs of auxiliary contacts (4) electrically connected with corresponding one or more input terminals (IN) and with said control unit (3) and adapted to be mutually coupled or separated; —a handle (8) movable in a first position (ON) corresponding to a closed state of said electronic protection device, in a second position (TRIP) corresponding to a tripped state of said electronic protection device or in a third position (OFF) corresponding to an open state of said electronic protection device; —an operating mechanism (5) adapted to operate said main contacts, said auxiliary contacts and said handle; —a tripping unit (6) adapted to actuate said operating mechanism (5) in response to an activation by said control unit. Said main contacts (2) and said auxiliary contacts (4) are coupled when said electronic protection device is in said closed state with said handle (8) in said first position (ON). Said main contacts (2) are separated and said auxiliary contacts (4) are coupled when said electronic protection device is in said tripped state with said handle (8) in said second position (TRIP). Said main contacts (2) and said auxiliary contacts (4) are separated when said electronic protection device is in said open state with said handle (8) in said third position (OFF).
