초록

A circuit interruption device includes a support, a set of separable contacts, a first member movable between an OFF position and an ON position, a second member, and a transport mechanism that includes a shape memory alloy element. When the first member is in the OFF position, the second member is in an extended position, the shape memory alloy element is in its first shape, and the first surface and the another first surface are engaged with one another and resist movement of the first member away from the OFF position. Responsive to an electrical puls...
