Abstract

The invention relates to a housing (20) for a magnet assembly (1), e.g. for housing a preferably annular magnetic core (2) of a differential current converter in a residual-current circuit breaker. According to the invention, the housing (20) consists of several parts and is configured from an insulation material. At least two conductive contacts (5) for connecting the ends (6) of at least one conductor loop (3), such as e.g. a secondary winding and / or a tertiary winding (4) of the differential current converter are configured on the housing. To improve the automated production of residual-current circuit breakers, the conductive contacts are configured as connecting conductors (8) of at least one electronic component.

Description

technical field [0001] The invention relates to a differential current converter for a fault current protective switch, comprising a preferably annular magnetic core; at least one conductor coil, such as a secondary winding and / or a tertiary winding; and a multipart , Shell made of insulating material. Background technique [0002] The magnet arrangement is, for example, a component of differential current converters used in fault current protective switches. The magnet core or its housing is surrounded here by the primary winding, which is connected to the terminals and contacts of the drum controller when used in a fault current circuit breaker. The secondary winding and / or the tertiary winding, which are arranged on the magnetic core or its housing, are connected to electronic components or component groups inside the switch. According to the usual configuration of fault current circuit breakers of this type, the connection to the component groups of the fault current c...
