Clip-on current transducer or current transformer

Electrical current transducer for mounting around an electrical primary conductor comprising a primary conductor receiving aperture, a housing, a magnetic core mounted in the housing, and a secondary coil wound around a branch of the magnetic core, the housing comprising a major portion and a minor portion, the major portion being separable from the minor portion and configured to be mounted and locked around the primary conductor, wherein the housing in a closed position has a primary conductor aperture extending through a central region of the magnetic core such that a primary conductor can be positioned in said aperture while the major portion and the minor portion of the housing are in an opened position, whereby the housing and the magnetic core can be split open to allow mounting and closing of the transducer around a primary conductor, the housing major and minor portions joinable together at joining faces, the magnetic core comprising a major portion mountable in a core receiving cavity of the housing major portion, and a minor portion mountable in a core receiving cavity of the housing minor portion, characterized in that the housing further comprises an electrical component support body comprising a coil support portion around which the secondary coil is mounted, the secondary coil and coil support portion being received in a first branch receiving portion of the core receiving cavity of the housing major portion, the coil support portion comprising a core receiving cavity comprising a first branch receiving portion receiving a first branch of the magnetic core major portion therein, a longitudinal axis (A) of the magnetic core first branch being in a transverse direction to the joining faces, wherein the housing major portion and housing minor portion are coupled together via a pivotable hinge and wherein the housing major portion and minor portion and hinge are integrally formed as a single injection molded part.
