    摘要： This breaker device includes: a holder including a first internal space and a second internal space located below the first internal space; a conductor located between the first internal space and the second internal space and held on the holder; a pusher disposed in the first internal space; and a drive source that moves the pusher from the first internal space toward the second internal space. The conductor includes: a first embedded portion held on the holder; a second embedded portion held on the holder; and a partition portion disposed between the first embedded portion and the second embedded portion. The pusher is located above the partition portion. The first embedded portion includes: a thin portion connected to the partition portion; and a thick portion located opposite the partition portion across the thin portion. The thickness of the thick portion in the up-down direction is greater than the thickness of the thin portion in the up-down direction.

    摘要： The present invention relates to a contactor device (100), which is capable of changing a connection state of at least two battery modules (502(1), 502(2)) of a high voltage energy storage system (10) between a series connection and a parallel connection, and to an energy storage system (10) comprising the contactor device (100). The contactor device (100) comprises two first terminals (102, 104) for electrically connecting at least one of a load and a charger, two second terminals (106, 108) for electrically connecting a first battery module (502(1)), and two third terminals (110, 112) for electrically connecting a second battery module (502(2)). The contactor device (100) further comprises two first bus bars (128, 129), which each are electrically connected to one of the first terminals (102, 104), and two second bus bars (138, 139; 238, 239), wherein one of the second bus bars (138; 238) is electrically connected to one of the second terminals (106), and the other one of the second bus bars (139; 239) is electrically connected to one of the third terminals (112), and a connection bus bar (144), which is electrically isolated from the two first bus bars(128, 129). At least one actuation element is configured to change a state of the contactor de-vice (100) at least to and from a series connection state, in which the two second bus bars (138, 139; 238, 239) are conductively coupled to the connection bus bar (144), and to and from a parallel connection state, in which one of the second bus bars (138; 238) is conductively coupled to one of the first bus bars (128) and the other one of the second bus bars (139; 239) is conductively coupled to the other one of the first bus bars (129).
