摘要： An integrated protection unit is a circuit breaker which includes basic overcurrent protection facility along with selective electrical accessories. A molded plastic accessory access cover secured to the integrated protection unit cover protects the accessory components from the environment. The accessory cover includes means for cooperating with a load center or panelboard circuit breaker enclosure to prevent access to the accessory components within the load center or panelboard interior.

摘要： A molded case circuit breaker movable contact arm or carrier electrically connects with the circuit breaker trip unit or load terminal without requiring a flexible electrical conducting braid. The contact carrier is pivotally arranged within a contact carrier support to which the trip unit or load terminal lug is attached. The contact carrier pivot pin is supported on a pair of parallel posts extending from the contact carrier and a spring clip is positioned around the parallel posts and the pivoting end of the contact carrier to promote good electric transport without interfering with the rotational movement of the contact carrier.
