Abstract

A fault current relay, consisting of a magnet system which is arranged in a housing (4) and has a spring-loaded hinged armature (2) whose tripping movement is transmitted to a plunger (3) which is arranged above the armature (2) on the housing (4), the magnet system being formed from a U-shaped yoke (J) on whose pole limb (11') remote from the armature bearing the coil former (1) is seated, with the fault current connection (12). According to the invention, the U-shaped yoke (J) is formed from an L-shaped yoke part (11), whose longer limb forms a pole limb (11'), and of a yoke part (7) which is bent twice into a shape similar to a S, rests with its one end limb (7') underneath the coil former (1) on the pole limb (11') of the L-shaped yoke part (11) with a non-magnetic film (10) placed in between, and, with its second end limb, forms a second pole limb (7''), and such that the permanent magnet (9) of the magnet system is arranged between the shorter limb (11'') of the L-shaped yoke part (11) and the connecting web, which forms the base web (7"') of the U-shaped yoke (J), of both end limbs of the yoke part (7) having approximately the shape of a S. <IMAGE>
