Novel current mutual inductor

The utility model discloses a novel current mutual inductor which comprises a mutual inductor body. The mutual inductor body comprises a mutual inductor main body and a mutual inductor neck. An iron-core coil is installed inside the mutual inductor main body. A shielding layer is arranged on the outer side of the iron-core coil. A secondary winding and a primary winding are wound around the iron-core coil. The primary winding provides a rated current ranging from 50 A to 2000 A. The secondary winding provides a switching current ranging from 1 A to 5 A. The primary winding is connected with a primary winding wiring terminal through a copper sheet penetrating through the mutual inductor neck, wherein the primary winding wiring terminal is arranged on the mutual inductor neck. The secondary winding is connected with a secondary winding wiring terminal through a wire, wherein the secondary winding wiring terminal is arranged on the mutual inductor main body. A mutual inductor flange plate is arranged at the lowe
