摘要： A reverse deflection prevention arrangement is provided for use in a circuit breaker for preventing a bimetal from bending in a direction opposite its normal thermal deflection. The reverse deflection prevention arrangement includes a tab portion extending from a yoke and a corresponding block member disposed on the inside surface of a circuit breaker cover. The tab portion engages the block member when the bimetal is forced to deflect in the direction opposite its normal deflection. An alternate embodiment of the reverse deflection prevention arrangement includes a reinforcement member secured to one end of the bimetal. The reinforcement member strengthens and supports the bimetal so that it is prevented from bending in the direction opposite its normal thermal deflection.

摘要： An arc suppressing assembly for use in a circuit breaker having at least one pair of separable contacts which includes an arc stack assembly in back-to-back relationship with a baffle assembly with the arc stack assembly in between the baffle assembly and the separablecontacts. The arc stack assembly includes a pair of insulating support legs having a plurality of parallel slots which receive tabs of respective and generally rectangular-shaped arc plates with a recessed front portion of each arc plate facing toward the contacts. The uppermost arc plate is provided with an extending runner portion which attracts an arc formed upon the opening of the contacts under certain current conditions. The baffle assembly similarly includes a pair of insulating side supports with a plurality of parallel slots provided therein to receive tab portions provided on the sides of generally rectangular insulating baffles. The association of the insulating baffles with the metallic arc plates imparts a generally wave-like motion to the venting gases. Each of the plates are at an angle of substantially 22.degree. to the horizontal with the gases first being directed upward by the arc plates and then downward by the baffles. A second set of baffles is provided behind a first column of baffles which are positioned in generally parallel relationship with the arc plates and further assist in the extinguishing and venting of the gases as they are blown away from the contacts.

摘要： An electrical contact for use in an electrical switching device is provided having low contact resistance, high wear resistance and high anti-weld characteristics. The contact includes a material composition of between 0.2 and 8% by weight Gr, between 10 and 90% by weight W and the remaining mixture consisting of Ag. The contact is manufactured using a process which yields a unique microstructure characterized by not having an interconnected Gr network around the Ag thereby providing a strong Ag to Ag bond. This process includes the steps of adding the appropriate amounts of Ag, W and Gr powder material together, blending together under low shear conditions to provide a homogenous powder mixture while prohibiting the Gr from smearing onto the Ag, pressing the material mixture to form a contact, and then sintering and coining the contact.

摘要： An improved miniature circuit breaker is provided which is adapted to improved automatic assembly of all components thereof. Key components of the breaker are individually and collectively designed to be susceptible to total Z-axis assembly. In particular, the circuit breaker operating mechanism which operates the contacts thereof to make or break the electric circuit is formed of elements designed to interact in a Z-axis assemblable fashion. The movable contact is defined on a contact carrier or blade assembly which is adapted for Z-axis assembly and also provides increased arc erosion resistance and improved opening of the breaker contacts.

摘要： A circuit breaker is provided having a stationary contact, a movable contact and a blade which has a first end and a second end. The movable contact is secured to the first end of the blade. The blade is rotatable about a pin between a BLOWN OPEN position and a CLOSED position, wherein the movable contact is separated from the stationary contact when the blade is in the BLOWN OPEN position and the movable contact engages the stationary contact when the blade is in the CLOSED position. The blade further has a protrusion portion extending from its second end. The circuit breaker further includes a catcher rotatably coupled to a pivot pin and having a nose portion for engagement with the blade protrusion portion. A spring is mounted about the pivot pin and engages the catcher for biasing the catcher towards the blade whereby the nose portion rests against the protrusion portion of the blade when the blade is in the CLOSED position and the nose portion overlaps the protrusion portion when the blade is in the BLOWN OPEN position thereby holding the blade in the BLOWN OPEN position.
