WIPO Patent Application WO/2024/034323
Kind Code:
A1
Abstract:
A current interruption device 100 comprises a plurality of breakers 1 having different operation temperatures connected in parallel with each other. The breakers 1 comprise: a fixed piece 2 having a fixed contact 21; a movable piece 4 that includes an elastic portion 44 capable of elastic deformation and a movable contact 41, and that presses the movable contact 41 onto the fixed contact 21 to establish a contact therebetween; and a thermally responsive element 5 that deforms in accordance with a temperature change, to thereby cause transition of the state of the movable piece 4 from a conduction state in which the movable contact 41 is in contact with the fixed contact 21 to an interruption state in which the movable contact 41 is separated from the fixed contact 21.
