Battery disconnect device

A battery disconnect device comprising:

• a breaker having a pivot portion and an actuation portion, the actuation portion having an actuation face, the pivot portion having an axis of rotation about which the breaker is pivotable;
• a housing defining a chamber, the chamber being in fluid communication with a gas generator via an inlet defined by an inlet wall of the housing;
• and
• a bus bar extending through the housing and the chamber,
• wherein the breaker is disposed within the chamber in a first position in which the actuation face is adjacent the inlet and inlet wall and combustion gas from the gas generator pushes on the actuation face to cause the breaker to pivot about the axis of rotation of the pivot portion to a second position, wherein in the second position, the actuation face is spaced apart from the inlet and inlet wall, and the pivoting movement of the pivot portion causes the breaker to break the bus bar, and
• wherein the bus bar extends through a groove defined in the pivot portion of the breaker, and the pivoting movement of the pivot portion causes the pivot portion to break the bus bar at a first recessed portion and a second recessed portion.
