Summary:FIELD: electrical engineering. SUBSTANCE: proposed automatic switch incorporates body with cover, free release mechanism with rack, contact system with arc chutes, thermal and electromagnetic maximum current release devices in each pole. Thermal release device is divided into two electrically parallel parts. Electromagnetic maximum current release device includes current conductor coming in the form of flat bus on which magnetic circuit and post with armature, spring and adjustment screw are anchored. EFFECT: increased current-carrying capacity without enlargement of overall dimensions. 2 dwg
