<P>PROBLEM TO BE SOLVED: To break contact between a movable contact arm and a stationary contact arm when a current path between the movable contact arm and the stationary contact arm has a current with not less than a predetermined amplitude. <P>SOLUTION: A circuit interruption device (100) comprises: a conductive element (218) configured to be coupled to a circuit; a contact arm (214) configured to move with respect to the conductive element (218) between a first position and a second position; and a biasing element (216) configured to apply biasing force on the contact arm (214) to maintain contact between the contact arm (214) and the conductive element (218) when the contact arm (214) is in the first position. The contact arm (214) is configured such that a current flow through the contact arm (214) causes electromagnetic repulsive force to act on the contact arm (214) in a second direction that is opposite a first direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
