Cost-efficient industrial-rated molded case breaker
 A molded case circuit breaker controlled by an electronic trip unit is cost-competitive with electromagnetic circuit interruption devices. A novel contact arm assembly and shield arrangement in combination with a contact arm spacer and operating cradle interface reduces the assembly time and the number of operating components to effect significant cost savings.
