Electrical current transducer including a magnetic core (6) comprising a magnetic circuit gap (22), a magnetic field detector (8) comprising a sensing portion positioned in the magnetic circuit gap, an insulating support body (10) comprising a coil support portion (26) and a coil terminal connection portion (28), and a secondary coil (12) formed from a wire wound around the coil support portion. The coil support portion has a generally U-shaped cross-sectional profile comprising a base wall (74a), a radially inner wall (74b) extending from the base wall and a radially outer wall (74c) extending from the base wall, the radially inner and outer walls (74b, 74c) having a height configured such that open end edges (80b, 80c) thereof extend slightly beyond an axial thickness of the magnetic core (6) including any manufacturing tolerances such that the open end edges (80b, 80c) are folded inwards around corners of the magnetic core by the coil wound around the magnetic core housing. |
