The arranged on the magnetic core or on the housing

Secondary winding and / or tertiary winding are connected to electronic components or assemblies within the switch. According to the usual types of such Febleratromschutzschalter the connection to the modules of the residual current circuit breaker by means of the wires which are used for the windings themselves, which are usually relatively thin and flexible, since a large number of windings can be applied to the magnetic core, without this mechanically load. Furthermore, by using thin wires, the ground, the measurements and the cost of a residual current circuit breaker can be kept low.

A disadvantage of such an embodiment of the connection of the secondary winding and / or the tertiary winding with the modules of a residual current circuit breaker that cause problems due to the small diameter and the high flexibility of the wires used in an automated manufacturing. The ends of such thin wires pose for a production machine, due to their insufficient dimensional stability, no defined position dar- Already a slight deviation of the actual position of a wire end of the preprogrammed position causes the machine no longer finds the wire end, creating a compound of Secondary winding and / or tertiary winding with the modules of a residual current circuit breaker is no longer possible. The connection of the secondary winding and / or the tertiary winding with the modules therefore largely takes place manually. This leads to high costs and high failure rates during production.

The Fig. 1 to 9 show different views of particularly preferred embodiments of a housing 20 for a magnet assembly 1, for example, for receiving a, preferably annular, magnetic core 2 of a differential current transformer of a residual current circuit breaker, wherein the housing 20 is formed in several parts and of insulating material, and on the housing 20 at least two conductive contacts. 5 for the connection of the ends 6 of at least one conductor loop 3, such as secondary winding and / or a tertiary winding 4 of the differential current transformer are formed, and wherein the conductive contacts 5 are formed as a connecting conductor 8 at least one electronic component 9. Magnetic arrangements 1 are used in current transformers electrical switching devices, especially residual current circuit breakers. They comprise a magnetic core 2 which in the preferred embodiments is formed by an annular magnetic core 2 with a rectangular cross-section.

The primary windings typically wrap around the cross section of the magnetic core 2 only one to one and a half times. The number of primary windings corresponds to the number of conductors of the network to be protected, usually two or four.

21. A differential current converter according to claim 20, characterized in that the receiving area (55) is provided for receiving at least one electronic component (9), preferably a component assembly (11).
22. A differential current converter according to one of the claims 15 to 21, characterized in that the connecting conductors (8) of the at least one electronic component (10) wired axially or radially are arranged substantially parallel to the outer housing surface (45) which is arranged substantially as a cylinder jacket surface (22).
23. A differential current converter according to one of the claims 15 to 22, characterized in that at least one electronic component (9), preferably a component assembly (11), is arranged in the support (29), with a secondary winding and/or tertiary winding (4) of the differential current converter being arranged via the support (29).
