摘要： A circuit breaker housing includes a base having a main portion and a separate subbase portion. The line contact arms for the breaker are mounted on the subbase portion and attached to the main portion which includes the load contact arms. The main portion of the base includes a bottom wall which insulates the load contact arms from the line contact arms along a portion of their lengths. In addition, the bottom wall forms a structural member which rigidly ties the two sidewalls of the main portion of the base. The bottom wall of the main portion of the base includes an opening through which line contacts coupled to the line contact arm make contact with load arm contacts coupled to the load contact arms. Adjacent to the opening, the main portion of the base includes vertical ribs directly tied to the bottom wall which strengthen internal and external side walls in the main portion of the base and reinforce the structural member formed by the bottom wall of the main portion of the base. The subbase may be attached to the base with screws, adhesives, a combination of screws and adhesives or by other methods.

摘要： A circuit breaker includes a cam assembly which holds the load blade in contact with the line strap during normal operation. The cam assembly includes a cam surface on a cam which can slide along the load blade and a bearing surface on the load blade. In normal operation, the cam is biased on the load blade so that the cam surface engages the bearing surface. The force applied by the cam surface to the bearing surface in normal operation is approximately parallel to the force applied by the load blade to the line strap, thus, the cam surface does not tend to slide along the bearing surface during normal operation. When a high overcurrent fault occurs, blow-open forces exerted between the load blade and the line strap cause the cam to pivot to a position where the cam surface no longer engages the bearing surface, allowing the load blade to swing free of the cam and break the contact between the load blade and the line strap. As the load blade swings free of the cam, it engages a further cam surface of the cam which reduces the biasing force essentially to zero, thereby increasing the opening speed of the blade. In addition, the frictional force of the further cam surface against the load blade prevents the load blade from reestablishing contact with the line strap until the mechanism trips, keeping the load blade in the open position.
摘要翻译：断路器包括凸轮组件，其在正常操作期间保持负载叶片与线束条接触。凸轮组件包括在凸轮上的凸轮表面，该凸轮能够沿着负载刀片滑动并且在负载刀片上具有支承表面。在正常操作中，凸轮被偏置在负载刀片上，使得凸轮表面接合支承表面。在正常操作中由凸轮表面施加到轴承表面的力大致平行于由负载刀片施加到线束带的力，因此，在正常操作期间，凸轮表面不会沿轴承表面滑动。当发生高过电流故障时，施加在负载叶片和线束带之间的吹开力使得凸轮枢转到凸轮表面不再与轴承表面接合的位置，允许负载刀片摆动而不受凸轮的影响，打破负载刀片和线束带之间的接触。当负载片摆动而不摆动凸轮时，它与凸轮的另一个凸轮表面接合，该凸轮的偏置力基本上减小到零，从而增加了叶片的打开速度。此外，另外的凸轮表面抵靠负载刀片的摩擦力防止负载刀片重新建立与线束带的接触，直到机构跳闸，保持负载刀片处于打开位置。

摘要： A remote tripping mechanism for use with a spring loaded safety switch. In a preferred embodiment, the mechanism is made up of two cams with a compression type trip spring anchored between them. The two cams are held in the "normal position" (the spring compressed) by a latch. In this position, the switch operates in the same manner as a conventional safety switch. A trip lever connected to a solenoid is positioned such that it is unobtrusive when the switch is turned ON and OFF. When the switch is in the ON position and power is applied to the solenoid, the trip lever unlatches the latch and the two cams separate. The first cam engages and lifts the bail, turning the switch OFF. The cams are reset by turning the handle to the OFF position. This compresses the trip spring and resets the latch.

摘要： A circuit breaker including a contact operating mechanism configured to prevent the switch handle of the circuit breaker from being placed in an OFF position when the contacts are not separable. In addition to the switch handle, the mechanism is operable with a tripping circuit which actuates the mechanism to urge the contacts apart when the current flowing through the circuit breaker exceeds the preset limits of the circuit breaker. When the contacts are not separable and the tripping circuit actuates the mechanism, the operating handle is restricted from being placed in the OFF position, thereby avoiding the possibility of indicating an incorrect position of the contacts.

摘要： A method for adjusting the calibration of a circuit breaker trip mechanism including a terminal element, a bimetal element connected thereto, and a trip bar. Laser energy is applied to lanced or pre-bent surfaces of the terminal element to thermally induce displacement thereof and thereby modify a trip distance between the bimetal element and the trip bar. Where a laser beam is directed to fall on a middle leg of a lanced or pre-bent section of the terminal element, the bimetal element moves in one direction relative to the trip bar. Conversely, where a laser beam is directed to fall on lateral legs of the lanced or pre-bent section of the terminal element, the bimetal element moves in an opposite direction relative to the trip bar. Thus, laser energy may be applied from the same direction, or to the same side of the trip structure, regardless of whether the trip time is to be increased or decreased.

摘要： A contact assembly (22) is adapted for use with a circuit breaker (12) that is set to open a circuit above a predetermined current load. The contact assembly (22) is adapted to reciprocate between a closed position to permit the flow of current through the circuit and an open position to prevent the flow of current. The contact assembly (22) is further adapted to resist unintended reciprocation from the closed position to the open position at current loads up to or exceeding the predetermined current load. The contact assembly includes a line side conductor (38) and a load side conductor (54). When in the closed position, a surface (42) of the line side conductor (38) extends proximal to a surface (56) of the load side conductor (54) and current flows in substantially the same direction along the line side and load side surfaces (42 and 56) to generate an electromagnetic attraction between the conductors (38 and 54) in order to resist unintended reciprocation of the contact assembly (22) from the closed position to the open position due to inherent repulsion forces present across the contact points (contact constriction forces). A circuit breaker assembly (10) and an automated control system (300) are also described.

摘要： A molded case circuit breaker includes a generally "Z" shaped intermediate latch structure which has upper and lower substantially planar sections that are each bent at an angle with respect to a center pivot section. The upper portion of the intermediate latch includes one or two latch surfaces. One of these latch surfaces engages the cradle of the operating mechanism of the circuit breaker, to latch the operating mechanism when the circuit breaker is closed. The other latch surface engages a trip bar or an intermediate latch bar, which is rotated by the trip unit when an overcurrent condition occurs. The lower portion of the intermediate latch structure also includes a latch surface which may engage a trip bar. This latch surface is sloped such that when the latch surface of the trip bar is moved along this sloped latch surface, the trip bar rotates. This rotation of the trip bar adjusts the spacing between the trip bar and a bimetallic strip or magnetic armature of a thermal and magnetic trip unit to allow the rating of the circuit breaker to be changed in the field. The pivot portion of the intermediate latch structure includes two mounting tabs, one on either side of the latch. The mounting tabs have a generally rectangular cross-section and, due to the angled relationship between the pivot portion and the upper and lower portions of the intermediate latch, the latch pivots on an edge of the mounting tabs. This edge is aligned with an angular opening in the mechanical frame to mount the intermediate latch. The mounting tabs also retain a biasing spring which biases the intermediate latch toward the cradle and biases the trip bar or latch bar toward the intermediate latch.
