Claim:
1. Electrical current transducer including a primary conductor bar for carrying the current to be measured, a magnetic core comprising a magnetic circuit gap, a magnetic field sensor comprising a circuit board and a magnetic field detector positioned in the magnetic circuit gap, and an insulating housing surrounding the magnetic core and magnetic field sensor, the primary conductor bar comprising connection terminal ends extending outside of the housing configured for connection to an external primary conductor, the primary conductor bar further comprising a core passage section having a reduced width (W1) in comparison to the connection terminal ends extending outside of the housing thereby providing an indent within which the magnetic field detector is positioned such that a central passage of the magnetic core has a width (W3) less than the width (W2) of the primary conductor connection ends, wherein the insulating housing comprises a main housing portion overmolded around the core passage section of the primary conductor bar, the main housing portion comprising a magnetic field sensor receiving slot configured to allow slidable insertion of the magnetic field sensor into the primary conductor bar indent for positioning in the magnetic circuit gap.
