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.
