A three-phase current sensor for measuring currents (I<SUB>PH</SUB> 1 , I<SUB>PH</SUB> 2 , I<SUB>PH</SUB> 3 ) running in three conductors of a three-phase conductor system comprises a first magnetic measuring device (D 1 ) and a second magnetic measuring device (D 3 ). Each magnetic measuring device comprises a magnetic circuit provided with at least two interleaf gaps and a magnetic field sensor arranged in each interleaf gap. The magnetic measuring devices (D 1 , D 3 ) are positioned on both sides of a central conductor or cavity, thereby enabling a central conductor to be inserted in such a way that one of three phases of the conductor system is formed.
