Abstract

A converter (1), for example a summing current transformer for earth-leakage current protection circuit breakers, through whose annular winding (2) at least one primary conductor (4) is passed, as a conductor, without being wound. It is provided that the conductor be bent (bend 5) in the form of a knee in the winding region in order that it finds a stop on a first radial rib (6) within the annular winding (2) and, in its straight-line region, rests in a guide trough (7) of a second radial rib (8), which is at an angle with respect to the first rib (6), at least one snapping hook (9) engaging in the bend (5), as a result of which the conductor (4) is secured against rotation and in the axial direction. <IMAGE>
