Abstract

See full text

A circuit breaker for automatically interrupting the flow of an electric current from a power supply to a load such as a microcomputer before the load malfunctions so as to avoid an unexpected accident such as a fire. The circuit breaker includes a wire subject to erosion upon exposure to an acid atmosphere which will separate prior to the malfunction of the load to interrupt the flow of current to the load. Alternatively, the circuit breaker could include a mass of powdery material which expands upon exposure to an acid atmosphere to operate a switch to interrupt the flow of current.
