摘要： An arc stack for receiving a circuit breaker blade moveable between a closed position and an open position, includes a plurality of arc plates positioned substantially parallel to one another and arranged in a plurality of adjacent groups. Each of the groups includes one or more arc plates having substantially similar respective arc throats formed therein. The respective arc throats progressively decrease in size from group to group along the length of the arc stack in a direction extending away from the closed position of the blade. A connecting support maintains the plurality of arc plates substantially parallel to one another.

摘要： A blade suspension assembly for a circuit breaker includes a first electrical contact, an elongated contact arm having a second electrical contact adjacent a first end of the contact arm, a compression spring, and an elongated lever. The second electrical contact is movable about a first pivot axis between a contacts-closed position and at least one contacts-open position with respect to the first electrical contact. The lever has a first end adjacent a second pivot axis, a second end supported by the compression spring, and a contoured support surface between the first and second ends which supports a second end of the contact arm. The compression spring exerts a force against the second end of the lever so that the contoured support surface biases the second end of the contact arm about the first pivot axis in the contacts-closed position during normal operation and in the contacts-open position in response to the contact arm moving to the contacts-open position.

摘要： A latch mechanism for a circuit breaker comprises a pair of longitudinal legs, a lateral section bridging the pair of longitudinal legs, and a longitudinal section extending from the lateral section in an opposite direction relative to the pair of legs. The lateral section includes a lower bearing surface for releasably engaging a cradle of the circuit breaker. The lower bearing surface includes a coined radius for facilitating engagement and disengagement of the cradle. The longitudinal section includes a protrusion for supporting a latch spring. The latch mechanism is manufactured in a single stamping operation, during which the protrusion is formed by cold extrusion.

摘要： A blade suspension assembly for a circuit breaker comprises a pivot pin, a torsion spring, an elongated blade, and a blade carrier. The torsion spring includes a lateral middle section, a pair of end legs disposed on opposite sides of the middle section, and a lateral hole extending therethrough. The blade includes an electrical contact mounted thereto, a lower bearing surface, and a lateral circular aperture. The blade carrier includes first and second pairs of bearing surfaces. To assemble the blade suspension assembly, the torsion spring is placed over the blade with the lateral middle section abutting the lower bearing surface of the blade, with the end legs disposed on opposite sides of the blade, and with the lateral hole in the torsion spring disposed in line with the circular aperture in the blade. Next, the pivot pin is inserted through the lateral hole in the torsion spring and through the circular aperture in the blade. The combination of the blade, the torsion spring, and the pivot pin is then inserted into the blade carrier with the pair of end legs abutting respective ones of the first pair of bearing surfaces and opposite ends of the pivot pin abutting respective ones of the second pair of bearing surfaces.

摘要： A contact blade assembly for a circuit breaker comprises a blade carrier, an elongated blade, and a toggle spring. The blade carrier includes a blade pivot and a first spring pivot. The elongated blade has an electrical contact mounted thereto and includes a second spring pivot. The blade is rotatably mounted to the blade pivot of the blade carrier for rotation between a closed position and an open position. The toggle spring is connected to the first spring pivot at one end and to the second spring pivot at the other end. The first spring pivot, the second spring pivot, and the blade pivot are arranged such that a toggle condition associated with the rotation of the blade relative to the blade carrier corresponds to the blade pivot being located in line and between the first and second spring pivots. The toggle spring biases the blade away from the toggle condition in a first direction while the blade is disposed in the closed position. The toggle spring biases the blade away from the toggle condition in a second direction opposite the first direction while the blade is disposed in the open position.
摘要翻译：用于断路器的接触叶片组件包括叶片载体，细长叶片和肘节弹簧。叶片载体包括叶片枢轴和第一弹簧枢轴。细长的刀片具有安装在其上的电接触并且包括第二弹簧枢轴。叶片可旋转地安装到叶片载体的叶片枢轴上，以在关闭位置和打开位置之间旋转。肘节弹簧在一端连接到第一弹簧枢轴并且在另一端连接到第二弹簧枢轴。第一弹簧枢轴，第二弹簧枢轴和叶片枢轴被布置成使得与叶片相对于叶片载体的旋转相关联的肘节状态对应于叶片枢轴位于管线中并且位于第一和第二弹簧枢轴之间。当叶片设置在关闭位置时，肘节弹簧在第一方向上将叶片偏离肘节状态。当刀片处于打开位置时，肘节弹簧在与第一方向相反的第二方向上将刀片偏离肘节状态。
