ELECTRIC CURRENT TRANSDUCER MODULE

摘要

Electric current transducer module comprising a magnetic circuit with a magnetic core (2) and an air gap (20), the magnetic core having a central passage (18) configured to receive a primary conductor (14) carrying a primary current to be measured. The electric current transducer module further comprises a signal processing circuit (8) including a circuit board (17) and contact terminals (32) for connection to external circuitry, and a magnetic field detector (4) arranged at least partially in the air gap (20) of the magnetic circuit. The electric current transducer module further comprises a magnetic core mounting support (6) comprising a molded support (15) and a grounding and fixing mechanism (12) configured to hold and rigidly fix the magnetic core (2) to the molded base to form a magnetic circuit unit (3). The magnetic circuit unit (3) is configured to be fixedly assembled to the printed circuit board.
