Abstract
Interruttore magnetotermico con taratura meccanica di protezione termica in cui l'involucro è provvisto di una apertura per rilevare con un sensore introdotto nella apertura la posizione di riposo relativa all'involucro della estremità libera di un elemento bimetallico di attuazione di protezione termica, incastrato su un supporto a sbalzo regolabile, così consentendo di regolare il supporto a sbalzo fino a far assumere all'estremità libera dell'elemento bimetallico una posizione di riposo predeterminata relativa all'involucro.Magnetothermic switch with mechanical calibration of thermal protection in which the casing is provided with an opening to detect with a sensor inserted in the opening the rest position relative to the casing of the free end of a bimetallic thermal protection actuation element, embedded on a adjustable cantilever support, thus allowing to adjust the cantilever support until the free end of the bimetallic element assumes a predetermined resting position relative to the casing.
