摘要： A circuit breaker having an arc suppressing means disposed adjacent a contactor section and including a first arc running plate extended from a fixed contactor and a second arc running plate opposed to the first arc running plate. The distance between the both arc running plates on the side close to the contactor section is minimized so as not to cause any spatial short-circuiting to occur. At portions of the both arc running plates defining the minimized distance, magnetic arc driving force motivated by mutually oppositely directed arc currents flowing through the respective arc running plates is increased to a large extent, whereby arc shifting to deion grid of the arc suppressing means can be performed effectively quickly.

摘要： An oil-filled distribution transformer having a primary disconnect switch disposed within the housing and utilizing two movable bridging contacts and four stationary contacts for completing a series circuit therethrough. The switch includes a trip mechanism, a bimetal element isolated from the current path through the switch and responsive to the temperature of the oil to activate the trip mechanism upon overtemperature condition, and a float mechanism attached to the switch and cooperating with the trip mechanism so that the float assembly will activate the trip mechanism when the oil level within the housing drops below a predetermined value.

摘要： A multipole circuit breaker having a housing with a top wall center recess receiving a center strut of an interior trim. An operating assembly is interconnected with a trip assembly through a translator link passing beneath the center recess and is operable by the magnetic assembly to assist the operating assembly in separating the breaker contacts in response to a fault current. A closure member overlapped by the interior trim prevents access to the load wires. A voltage reject configuration is provided on the housing to prevent mounting in a panelboard designed to carry voltages higher than that for which the circuit breaker is rated and a jaw assembly for the breaker is disclosed having a plurality of contact positions with each leg of a U shaped bus stab.

摘要： The contacts of a conventional molded case residential circuit breaker are opened and closed in relay fashion by a remotely controllable operator module. The operator module, utilizing the compliance of the breaker operating mechanism in its ON condition, acts directly on the breaker movable contact arm to effect a separation of the movable contact from the stationary contact sufficient to switch rated current.

摘要： A molded case current limiting circuit interrupter includes a pair of pivoting contact arms each supporting a contact and being connected to wiring terminals such that current flows through the contact arms in opposite directions. One of the contact arms has a movable pivot point. A magnetic drive slot motor device is provided to generate electrodynamic contact opening force upon the contact arms during short circuit conditions. A high-speed magnetic trip device releases the operating mechanism under short circuit conditions to move the arm pivot point before the contact arms reclose. A spring latch may be provided to latch the upper contact arm in a contact-separated position during short circuit conditions until such time as the overcurrent flow through the breaker operates a thermal and magnetic trip mechanism to move an operating mechanism to the tripped position. Alternatively, a cam may be provided which is connected by a link to the upper contact arm and positioned such that upon short circuit conditions the contact opening motion of the upper contact arm caused by electrodynamic repulsion forces will cause the connecting link to rotate the cam and move the armature of the magnetic trip device to actuate the trip mechanism and release the operating mechanism to the tripped position, thereby preventing reclosing of the contact arms before the operating mechanism is able to trip. The operating mechanism includes a bracket to allow normal contact reset yet provide a positive closed contact indication if the contacts are welded together. An anti-rebound contact arm shock absorber is provided which is made of material having a high mechanical hysteresis loop to provide maximum energy dissipation.

摘要： A single pole molded case circuit breaker is constructed with an internal metal frame to which the contact operating mechanism is mounted. This mechanism includes a releaseable cradle which when latched permits the circuit breaker contacts to be closed. The cradle is a single element having spaced parallel walls, a latching extension on one of these walls and a kicker on the other wall. When the cradle is released or tripped the kicker is engageable with a toggle interposed between the contacts and the cradle for collapsing the toggle to assure contact opening. Integral formation on the walls provide a pivotal mounting for the toggle. A reset pin is loosely mounted between the parallel walls for low friction resetting of cradle.

摘要： A circuit breaker comprising a case and a stationary contact mounted within said case. A movable contact is movable into and out of engagement with the stationary contact. An operator is pivotally mounted within said case and a collapsible linkage interconnects the said operator and the movable contact. An electromagnetic sensing device collapses the collapsible linkage upon predetermined electrical overloads to move the contacts from the contacts "closed" position to the contacts "open" position. The collapsible linkage carries a restraining means for restraining the operator in a position intermediate the "open" and "closed" positions of the contacts.
