FIELD: electrical engineering.
SUBSTANCE: invention relates to a residual current device, used for protection from failure current, made with a tripping device, which has a tripping arm (3), which can rotate, for tripping the switching device, and an actuating device for moving the tripping arm (3) from hold position to tripping position with an actuating element in form of a push rod (5). Angular position of the tripping lever (32) of the tripping arm (3) relative half-shaft (7), which clicks with the energy accumulator (1), can be varied about a common axis of rotation. Variation of this angle is preferably done using a fixing mechanism (33, 37).
EFFECT: increased accuracy of adjusting distance between the push rod (5) and the tripping part (34) of the tripping arm without special tools.
