Abstract
An arc plate for a circuit breaker includes a body and a magnetic coating that covers an exterior of the body. The magnetic coating is a metal matrix composite including from 80 to 92 volume percentage of a metal that is magnetic, and from 8 to 20 volume percentage of particles. The particles have a higher melting temperature than the metal.
