The control circuit (46) has a frame (74, 76) and is configured to receive the sense signal and to provide a trip signal on a first terminal (68). The actuator (42) is external to the control circuit frame (74, 76) and has a second terminal (98) coupleable to the first terminal (68). The actuator (42) is configured to receive the trip signal on the second terminal (98).

摘要： The circuit breaker (10) of the present invention is a molded case circuit breaker and includes a molded case (12) having a main cover (20), a first terminal (16) and a second terminal (16) mounted inside the case (12) with a stationary contact (44) electrically coupled to the first terminal (18) and a movable contact (42) electrically coupled to the second terminal (16). The movable contact (42) is coupled to an operating mechanism (40) which has a pivoting member (13) moveable between an ON position, an OFF position and a TRIPPED position. An intermediate latching mechanism (52) also is mounted in the housing (12) and is coupled to the operating mechanism (40). The intermediate latching mechanism (52) is selectively operated by a trip unit (60) which comprises a magnetic short circuit release and a thermal overload release. The trip unit (60) can be reconfigured by the addition of an inner yoke (67) nested between the flanges (71) of an outer yoke (66) and a second magnetic shield (70) can be attached to the outer yoke (66) to change the sensitivity of the trip unit (60) to the currents experienced by the circuit breaker. A particular embodiment of the circuit breaker (10) includes an interchangeable bi-metal (62) member of a copper alloy having a chemical composition of CDA #19400 and with an electrical conductivity of not more than 40% IACS.

摘要： A circuit breaker (10) has a housing (12). A crossbar (114) is pivotally connected to the housing to pivot about an axis (117) between open and closed positions. A load contact arm (110) is pivotally connected to the crossbar (114). The load contact arm (110) is capable of pivoting about the axis (117). A cam mechanism (140) is mechanically coupled to the load contact arm (110). The cam mechanism (140) is slideably mounted within the crossbar (114) for movement between first and second positions. In the first position of the cam mechanism (140), the load contact arm (110) pivots through an angle (.beta.) about the axis, relative to the crossbar (114) between the "touch" and closed positions, and the load contact arm (110) pivots together with the crossbar (114) through an angle (.alpha.) about the axis (117) between the open and "touch" positions. (2) In the second position of the cam mechanism (140), the load contact arm (110) is free to pivot about the axis (117) through the angle .alpha. to the open position while the crossbar (114) is in the closed position. A biasing spring (160) applies a biasing force to bias the cam mechanism (140) towards the first position.

摘要： A drawout and interlock assembly for manually inserting a low-voltage molded case circuit breaker into positive electrical engagement with the plug-in power terminals of a distribution switchboard panel and then withdraw the breaker into a disconnected-test position is disclosed. The drawout position of the assembly comprises a pair of guide rails and a pair of drive rails that are secured to the back of the circuit breaker housing and cooperate with a pair of support rails and a drive mechanism that are secured to the stationary power blocks of the switchboard panel to effect a sliding telescopic interfitting of parts that permits the circuit breaker to be manually racked into connected and disconnected-test positions in an efficient reliable manner with a minimum number of parts. Automatic tripping of the breaker before it is connected to or disconnected from the switchboard panel is achieved by a toggle-actuated interlock lever that engages a depressable interlock button on the back of the circuit breaker housing when the drive mechanism is moved by an operating handle.

摘要： A thermal and magnetic trip unit for a multi-pole circuit breaker includes a thermal structure having a bimetallic element and one or more heater elements. Each of the heater elements and a portion of the bimetallic element is generally "U" shaped defining a conductive path which extends from one leg of the U to the other leg. The heater elements and bimetallic element may be configured in parallel to reduce the level of current flowing through the bimetallic element and thus increase the current level at which the bimetallic element will trip the breaker. Alternatively, the heater elements may be configured in series with the bimetallic element, by inserting electrical insulators between the bimetallic element and each of the heater elements and connecting the various "U" shaped elements using a connecting bus which connects the second leg of one element to the first leg of the next element. In this configuration, the thermal structure defines a coil having one turns for each heater element and the bimetallic element. This coil may be used to implement a magnetic trip structure by inserting one or two magnetically permeable yokes, each yoke surrounding one leg of the combined thermal structure. An armature is positioned to be separated from the yoke by a gap such that, when the armature is pulled toward the yoke, it will engage the trip unit. In addition, the trip unit includes a calibration and adjustment bar that allows the gap to be adjusted as well as the force exerted on the armature by a biasing spring. The calibration and adjustment bar also allows each pole of the circuit breaker to be independently calibrated.

摘要： An improved circuit breaker with moving line and load contacts is disclosed herein. The circuit breaker includes an enclosure for the operational components thereof including a line contact arm and associated contact for each phase of the circuit breaker, and an operating mechanism supported within the enclosure to move the contact arm(s) between open and closed positions. The circuit breaker also includes a terminal for each phase pivotally supported within the enclosure, and a load contact arm and associated contact for each phase pivotally connected to the terminal. The contact arms are supported so the contacts are engaged when the line contact arms are in the closed positions. The pivoted load terminal(s) allow the use of multiple connector types with the terminal(s), and the pivoting connection between the load contact arm and associated terminal facilitates a reduction in circuit breaker size for a given rating.
