摘要:
A magnet core (1) which is suitable for use in a residual current device and is composed of a spirally wound soft-magnetic strip has an upper face (4) and a lower face (5), wherein the upper face (4) and the lower face (5) are formed by side surfaces (16) of the soft-magnetic strip. The magnet core (1) is fixed in a protective housing (6) and, in order to fix the magnet core (1), an adhesion adhesive (11) is provided between the lower face (5) of the magnet core (1) and a housing inner wall (10).
