Electrical current transducer including a housing (5), a magnetic field detector device (3) comprising a magnetic field sensing element (11), and a magnetic circuit comprising a magnetic core (4) with a gap (6) and a bridging device (8) mounted on the magnetic core and spanning across the gap. The bridging device comprises a gap positioning element (26) made of a non-magnetic material inserted in the gap configured to determine a minimum width of the gap. The bridging device comprises at least two parts (8a, 8b), a first part mounted against a first lateral side (14a) of the magnetic core and a second part mounted (8b) mounted against a second lateral side (14b) of the magnetic core opposite the first lateral side, at least one of the first and second parts comprising fixing extensions (30) cooperating with the other of the first and second parts configured for clamping together the first and second parts around a portion of the magnetic core comprising the gap. |
