CURRENT TRANSDUCER WITH MAGNETIC FIELD DETECTOR MODULE

An electrical current transducer (2) comprising a magnetic core (6) and a magnetic field detector module (8), the magnetic core and magnetic field detector module each forming a single unit separably mountable around a primary conductor (4) and to a circuit board (10), the magnetic core having a general U shape comprising an end branch (14a) and lateral branches (14b) extending the end branch to respective free ends (14c), the magnetic field detector module being positioned between the lateral branches and extending across a whole width of a gap formed between the lateral branches. The magnetic field detector module comprises at least one magnetic field sensing cell (16), a pair of magnetic concentrators (22) arranged in mirror opposition forming a magnetic field gap (26) therebetween in which the at least one sensing cell is positioned, and an insulating body (20) supporting the magnetic concentrators and at least one sensing cell.
