摘要： A molded case circuit breaker of the type containing an electronic trip unit and a combined actuator-accessory unit to articulate the circuit breaker operating mechanism employs an optimum cradle configuration within the circuit breaker operating mechanism. The operating cradle is fabricated from a steel composition that is optimized to promote improved hardness properties. The optimized cradle interacts with the circuit breaker latch assembly to substantially reduce the tripping force required to articulate the operating mechanism.

摘要： An integrated protection unit is a circuit interrupter 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 contained within the integrated protection unit cover from the environment. A combined overcurrent trip actuator and multiple accessory unit can be field-installed within the integrated protection unit. The combined actuator-accessory unit includes electronic control circuitry for the accessories along with mechanical trip and reset interface components. One such accessory used with the integrated protection unit is a bell alarm for indicating the status of the circuit interrupter contacts.

摘要： An integrated electronic trip molded case circuit breaker includes a trip unit circuit arranged on a printed wire board contained within the breaker enclosure along with at least one circuit breaker auxiliary accessory. The condition of the integrated circuit breaker contacts is visually ascertained by a color-coded operating handle skirt subjacent indicating windows on the cover of the circuit breaker enclosure. To deter the egress of ionized gas during overload current conditions through the circuit breaker, the handle skirt seals the operating handle opening from the external environment. A groove formed within the external portion of the operating handle cooperates with an edge surface of the enclosure cover to allow the operating handle to rotate between its fully "OFF" and "ON" positions.

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.

摘要： A combined trip actuator and accessory module for molded case circuit breakers is accessible in the field for user selected accessory options. The trip actuator includes a U-shaped stator with a permanent magnet at the end of one leg. A spring-loaded armature member extends across both legs to form a closed-loop magnetic circuit. The over-current trip coil and shunt trip coil are arranged on one leg with the undervoltage coil arranged on the other leg. The accessory module is accessible from the top surface of the breaker cover for field installation of the undervoltage and shunt trip coils to provide the corresponding undervoltage and shunt trip functions.

摘要： A movable contact arm for circuit breakers allows the contact opening characteristics to be determined over an entire range of breaker ratings. The contact arm is provided with a camming surface with the contact closure spring arranged as a cam follower. Under short circuit conditions, the contact repulsion force is sufficient to overcome the bias provided by the contact closure spring and to drive the cam follower along the camming surface so that the resulting spring torque rapidly changes from a high initial torque on the contact arm to zero torque in a very short period of time. The contact arm is linked with the contact operating mechanism to open upon current overload in response to the trip mechanism.

摘要： A shield assembly for isolating line and load stabs within a circuit breaker compartment when the circuit breaker is removed from the compartment. The assembly consists of a pair of separately hinged shields interconnected by a link which terminates in a moveable pin. The pin is captured in a first slot within the assembly actuator arm and in a second slot within a supportive side frame. Movement of the actuator arm in a first direction causes the connecting link pin to move within the first slot to open the shields. Return of the actuator arm in an opposite direction causes the connecting link pin to travel within the second slot in an opposite direction to close the shields. The shield assembly contains actuating mechanisms at both sides of the breaker compartment in order to defeat any attempt by an operator to open the shields with the breaker withdrawn from the compartment.

摘要： A slideably mounted insulating shield is positioned over the terminals of a secondary disconnect attached to the side wall of a circuit breaker compartment. Inserting the circuit breaker into the compartment brings the secondary disconnect terminals on the breaker into engagement with the secondary disconnect terminals in the compartment by displacing the insulating shield. Removal of the breaker from the compartment forces the insulating shield to return to position over the compartment secondary disconnect terminals thereby isolating the disconnect terminals from inadvertent contact with an operator.
