Abstract

Selon cette invention, un élément de résistivité à coefficient de température positif (PTC) présente une résistivité qui augmente au fur et à mesure que la température augmente. Des disjoncteurs comportant ces éléments PTC peuvent permettre d'atteindre une meilleure protection contre la surcharge et les courts-circuits par rapport à des produits existants. Ce type de disjoncteur est également conçu comme dispositif de limitation courant pour appareils à tensions basse, moyenne et haute dans lesquels la formation d'arcs est réduite et l'arc soufflé par interposition d'un corps isolant entre les contacts.
