Abstract

1. Method for the adaptation of surfaces (3, 4) forming interferric gaps of a trip device, in particular for fault current safety switches, which comprises a low-retentivity pole piece (2), having one or more parts, with a trip coil, an armature (1) and a permanent magnet (7) for generating the armature keeping flux and a spring for storing a trip force acting against the armature keeping flux, characterised in that after the surfaces (3, 4) forming interferric gaps between the armature (1) and the pole piece (2) have been finely machined in the conventional manner by cutting shaping, and the parts of the trip device mounted, the pole pieces (2) and armature (1) are adapted to one another by ultrasonics.
