Abstract
Design for an automatic electrical interrupter with at least two nominal currents, comprising a bimetallic plate which has one end secured to a conductor support and its other free end situated in proximity of a mechanism for opening the contacts of the interrupter, characterised in that the different nominal currents are obtained by arranging for a more or less large fraction of the bimetallic plate being bypassed via a contact which can be controlled by closing means: in this way, the quantity of thermal energy absorbed by the bimetallic plate can remain the same, by making an appropriately larger current (= higher nominal current) flow through a smaller segment of the bimetallic plate. <IMAGE>
