Abstract

A circuit breaker having a monolithic structure and method of making is disclosed. The monolithic structure includes an arm portion having copper and a contact portion having a composite material. The composite material has a metallic matrix and a second phase disposed in the metallic matrix. The method of making the monolithic structure includes introducing a first powder into a first region of a mold, introducing a second powder into a second region of the mold, and consolidating the first powder and the second powder together. The first region of the mold corresponds to a contact portion, and the second region corresponds to an arm portion of the monolithic structure of the circuit breaker. FIG. 2.
