摘要： A circuit breaker having at least one cassette for receiving a conductive path. The conductive path is partially looped upon itself so that a first portion and a second portion of the conductive path are in a facially spaced relationship and the portions partially define an area for receiving a ferromagnetic material. The ferromagnetic material is insulated from the first portion and a support structure provides support for the first portion at two positions and the area is positioned in between these positions.

摘要： A molded case circuit breaker housing employs a tri-furcated design that imparts structural stability and manufacturing efficiency. The design provides a separate top cover, mid-cover and base wherein the mid-cover wall height to base wall height ratio is such that the stresses imparted upon the base sidewalls when pressures are exerted, for example, by gaseous discharges are withstood.

摘要： An operating mechanism controls and trips a separable contact structure arranged in a protected circuit. The mechanism includes a frame, a drive member pivotally coupled to the frame, a spring pivotally connecting the drive member to a drive connector, an upper link pivotally seated on the drive connector, a lower link member pivotally coupled to the drive connector, a crank member pivotally coupled to the lower link member for interfacing the separable contact structure, and a cradle member pivotally secured to the frame and pivotally securing the upper link. The cradle member is configured for being releasably engaged by a latch assembly, which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism is movable between a tripped position, a reset position, an off position, and an on position. Spacers are operatively positioned between movable members, and protrusions are operatively formed on the enclosure of the contact structure. The spacers and protrusions serve to widen the stance of the operating mechanism for force distribution purposes, and also to minimize friction between movable components.

摘要： A rotary double-break circuit breaker includes a case defining a circuit breaker enclosure with a rotatable bridge and contact arm arrangement. The contact arm having movable contacts which is rotatable between a closed position and an open position. A pair of stationary contacts cooperate with the movable contacts, and a conductor is operatively connected to each of the stationary contacts for current input thereto. Each of the movable contacts includes a heel portion and a toe portion, the heel portion contacting one of the stationary contacts and the toe portion spaced from the stationary contact when the contact bridge is in closed position, the movable contact being angled or curved relative to the stationary contact such that upon the contact bridge rotating to disengage the movable contacts from the stationary contacts, an electric arc formed between the movable contact and the stationary contact runs to the toe portion of the movable contact thereby protecting the heel portion from substantial damage.
