摘要： A circuit breaker includes a first section and a second section with independently operating pairs of contact assemblies in each respective section. In the first section, at least one of the contact assemblies is constructed and arranged to interrupt the current by moving from a normally closed position to a blown-open position and latching with the contact assemblies separated. The second section has a biasing extension spring for biasing the contact assemblies of the second section so as to permit interruption of the current in response to a blow-open force, which causes the contacts to separate only momentarily and then return to a normally closed position. The first and second pairs of contact assemblies separate substantially simultaneously in response to the blow-open force, and only the first section reacts to lower-level over-current conditions. In addition to the contact assemblies, the second section of the circuit breaker is designed to operate using only a spring which is "Z-axis" mountable. Other aspects of the invention include one-piece tripping actuator, a screw retainer assembly for securing the line or load terminal, a bimetal arrangement involving an improved calibration process and an associated stress-reducing line terminal.
摘要翻译：断路器包括第一部分和第二部分，其在每个相应部分中具有独立操作的接触组件对。在第一部分中，至少一个接触组件被构造和布置成通过从常闭位置移动到吹开位置并且与接触组件分离的闩锁来中断电流。第二部分具有用于偏压第二部分的接触组件的偏置延伸弹簧，以便响应于打开的力使中断电流，这使得触头只能瞬间分离，然后返回到常闭位置。第一和第二对接触组件响应于吹开力基本上同时分离，并且仅第一部分对较低级别的过电流条件作出反应。除接触组件之外，断路器的第二部分设计成仅使用可安装“Z轴”的弹簧进行操作。本发明的其它方面包括一体式跳闸致动器，用于固定线路或负载端子的螺钉保持器组件，涉及改进的校准过程的双金属装置和相关联的应力减小线路终端。

摘要： A mid terminal for a double break circuit breaker comprises first and second elongated conductive plates, where each of the plates have first and second ends. The second end of the first plate is longitudinally spaced from the first end of the second plate and the first end of the first plate is connected to the second end of the second plate by a lateral conductive plate. A first arc runner is electron beam welded to the second end of the first plate, and a second arc runner is electron beam welded to the first end of the second plate. The first and second arc runners are preferably made of steel. A first stationary contact is mounted on the first plate adjacent the first arc runner, and a second stationary contact is mounted on the second plate adjacent the second arc runner. To manufacture the mid terminal, the first and second plates and the lateral plate are formed from a single strip of copper bent into a shape having a pair of longitudinal sections extending in opposite directions from opposing ends of a lateral section. The longitudinal sections correspond to the first and second plates, and the lateral section corresponds to the lateral plate.

摘要： A high current capacity blade for a circuit breaker, comprises a conductive blade body having front and rear sections connected to one another, where the rear section includes a surface attachment area for fastening a flexible connector of the circuit breaker thereto. A strain relief tang extending from the rear section of the blade body is used to engage the flexible connector so as to stabilize the fastening of the flexible connector to the surface attachment area. A broad conductive lateral section is connected to and extends laterally from the front section, and includes a blade tab for engaging a toggle spring of the circuit breaker. A broad moveable contact is mounted on the broad lateral section and is adapted to interface with a stationary contact of the circuit breaker. A pair of substantially parallel L-shaped blade legs are spaced from one another to permit the toggle spring to pass therebetween. Each of the blade legs has first and second ends with the first ends connected to the rear portion of the blade body and the second ends including respective blade pivots for engaging notches in a handle of the circuit breaker. The assembly accommodates automated Z-axis assembly.

摘要： An electrical device, such as a circuit breaker, for interrupting the flow of current, which includes a stationary contact, a blade having a movable contact, a releasably latchable trip lever, a bimetal, and a magnetic armature. The movable contact is movable into and out of engagement with the stationary contact. The trip lever is releasable from a latched position for movement to a tripped position to cause separation of the stationary and movable contacts. The bimetal causes the release of the trip lever from the latched position by having the armature drawn a predetermined distance in response to a predetermined short circuit current. The trip lever is held in the latched positioned by a hardened latch having a minimal surface area, which is positioned near an opening located in the armature. When the predetermined short circuit current flows through the bimetal, the trip lever moves to the tripped position.
摘要翻译：用于中断电流流动的电气设备，例如断路器，其包括固定触点，具有可动触点的刀片，可释放地闩锁的脱扣杠杆，双金属和磁性衔铁。可移动触点可移动进入固定触点和与固定触点脱离接合。脱扣杆可从锁定位置释放，以移动到跳闸位置，从而导致固定和可移动触点的分离。双金属通过使电枢响应于预定的短路电流被拉伸预定距离而导致脱扣杆从闩锁位置释放。脱扣杠杆通过具有最小表面积的硬化闩锁保持在闩锁定位中，该表面面积位于靠近衔铁处的开口附近。当预定短路电流流过双金属片时，跳闸杆移动到跳闸位置。

摘要： A double break circuit breaker includes a pair of contact assemblies, an arc stack and an arc extractor. At least one of the contact assemblies interrupts the current by moving from a normally closed position to at least one open position, and the arc stack is disposed sufficiently adjacent the pair of contact assemblies to absorb arc energy resulting from one of the primary contact assemblies moving from the normally closed position. The arc extractor has a conductive portion located adjacent the arc stack and sufficiently adjacent the pair of contact assemblies to prevent the arc energy within the arc stack from collapsing into a region between the pair of contact assemblies.

The first and second pairs of contact assemblies separate substantially simultaneously in response to the blow-open force, and only the first section reacts to lower-level over-current conditions. To prevent welding or sticking of the contacts in the second section, a kicker is interposed between the pairs of contact assemblies so as to slightly open the contact assemblies in the second section in response to the contact assemblies of the first section reacting to the lower-level over-current conditions. The circuit breaker is designed to operate using "Z-axis" mountable components.

摘要： An arc stack for receiving a circuit breaker blade moveable between a closed position and an open position comprises a plurality of generally rectangular arc plates having substantially similar length and width dimensions and positioned substantially parallel to one another. The straight edges of the arc plates are in line with one another so that the arc stack is generally rectangular in shape. The arc plates have respective arc throats formed therein having a plurality of sizes so as to form a longitudinal passageway extending through the arc throats following the arc generated by the blade moving between the closed and open positions. The arc plates include sets of arc plates with the arc plates in each set having identical arc throats. The sets of arc plates are arranged in order of decreasing arc throat size with the set having the largest arc throats being positioned adjacent the circuit breaker blade in the closed position. The arc stack is formed in two sections with each section including a selected number of arc plates. The arc plates in each section are interconnected by a pair of side fibers engaging associated edges of the arc plates. The two sections are connected to form the arc stack by engaging the inner edges of the pair of side fibers of one section with mating inner edges of the pair of side fibers of the other section.
