Abstract: Electrical current transducer for measuring an electric current in a primary conductor, including a housing (4), a magnetic core (6) surrounding a central aperture (9) through which the primary conductor extends, and a magnetic field sensing device (8) comprising connection terminals (18). The housing comprises a magnetic core receiving cavity (22) in which the magnetic core is lodged and a connecting interface portion (25) in which the magnetic field sensing is lodged, the connecting interface projecting outwardly from the magnetic core receiving cavity and comprising latching elements complementary to latching elements of a separate connector interface element (11) selectively mountable to the connecting interface portion. The connector interface element comprises a connector shroud (14) forming with the connection terminals a pluggable connector interface for pluggable connection to an external pluggable connector, the current transducer adapted for mounting on an external circuit board without connector shroud.
