KRETSBRYTARANORDNING MED FJERRMANOVRERAT OPPNANDE OCH SLUTANDE AV DESS KRETSAR

摘要

A circuit breaking apparatus with remote controlled opening and closing of its circuits is provided in which the supports of the fixed and mobile contacts are adapted so as to develop repulsion forces which produce an excellent limitation of the short circuit currents because no parasite mass is connected to the mobile contact despite the presence of an electromagnet which must actuate it through a pusher or a slide.
