FIELD: supporting structures for mounting electrical devices. SUBSTANCE: proposed supporting structure that can be used for fixing electrical device on assembly duct along the latter, at certain distance from assembly duct, inside assembly duct, or without such duct is disposed, for instance, inside device casing but preferably has at least means in the form of grooves on each of its two opposing sides designed for mounting them on projections of assembly duct base, if necessary; coupled with supporting structure and used as auxiliary locating means is plate with at least two projecting posts each carrying latching means on its top. Supporting structure has hole in flange for each plate, each being provided with additional means for latching on plate posts which makes it possible to secure supporting structure on posts. EFFECT: unified design, facilitated manufacture, reduced cost of supporting structure. 16 cl, 9 dwg
