Abstract

An electrical breaker responsive to a fault condition is disclosed. A thermally-activated switch can be disposed between a first terminal and second and third terminals of the breaker. The switch can have a normal operating condition in which the first terminal is electrically connected to the second terminal. The switch can have a fault condition in which the first terminal is electrically connected to both the second terminal and the third terminal, causing a majority of the current to flow between the first terminal and the third terminal and a minority of the current to flow between the first terminal and the second terminal. The breaker can include a positive temperature coefficient (PTC) resistor between the first terminal and one of the second and third terminals. The thermally-activated switch can be integrated into a variety of structures, for example, a battery pack which can house one or more cells.
