Abstract

L’invention concerne un contacteur (1A), comprenant un actionneur (30) équipé d’un générateur de gaz (31) et d'un mécanisme de commande à gaz (32). Le générateur de gaz (31) génère un gaz à haute pression en faisant réagir un agent générateur de gaz dans le cas où un contacteur mobile (13) et un contacteur fixe (12) sont fusionnés l’un à l’autre. Le mécanisme de commande à gaz (32) est entraîné par le gaz à haute pression qui est généré par le générateur de gaz (31) et sépare le contacteur mobile (13) du contacteur fixe (12).
