Abstract:
A magnet core (1) that is suitable for use in a fault current circuit breaker and that is made of a helically wound, magnetically soft band has a top (4) and a bottom (5), the top (4) and the bottom (5) being formed by side surfaces (16) of the magnetically soft band. The magnet core (1) is fixed in a protective housing (6), and there is a contact cement (11) between the bottom (5) of the magnet core (1) and an inside wall (10) of the housing for fixing the magnet core (1).
