Abstract
L'invention est relative à un dispositif électromagnétique d'ouverture d'un bras de contact permettant d'obtenir un disjoncteur à tenue électrodynamique contrôlée jusqu'à un seuil de surintensité déterminé, et rapidement limiteur au-delà. Le dispositif électromagnétique 44 comporte un circuit magnétique 46 à circuit principal doté d'un premier entrefer E s'étendant transversalement à la direction longitudinale du bras 28, et une zone saturable 66, 68, agencée dans un circuit dérivé de shuntage du premier entrefer E et dont le passage de l'état non saturé à l'état saturé, s'effectue après dépassement dudit seuil de surintensité. Application disjoncteurs multipolaires BT.
