    Abstract: An electrical switching apparatus includes a housing, a line terminal, a load terminal, separable contacts disposed on a conductive path between the line terminal and the load terminal, an operating mechanism structured to open and close said separable contacts, said operating mechanism including a trip bar, and an electronic trip unit. The electrical switching apparatus also includes a trip actuator assembly including an actuator housing coupled to said housing, an actuator coupled to said actuator housing, and a connector structured to electrically connect the actuator to an electronic trip unit. The electrical switching apparatus further includes a current transformer assembly including a rod-shaped conductor electrically coupled to the load terminal and a current transformer disposed around the rod-shaped conductor, wherein the electronic trip unit is structured to electrically control actuation of the actuator.

    Abstract: A lever assembly is for an operating mechanism of an electrical switching apparatus. The electrical switching apparatus includes a number of pairs of separable contacts structured to move from a CLOSED position to a TRIPPED OPEN position in response to a trip condition. The operating mechanism has an enclosure member and a number of biasing elements coupled to the enclosure member. The biasing elements are structured to move the separable contacts from the CLOSED position to the TRIPPED OPEN position. The lever assembly includes a lever member structured to engage the enclosure member, and a component located on the lever member. The component is structured to extend through each of the biasing elements in order to lengthen each of the biasing elements when the separable contacts are in the CLOSED position.

    Abstract: An adaptor assembly is provided. The adaptor assembly is structured to allow a cable of a first amperage to be coupled to, and placed in electrical communication with, a terminal of a different amperage. That is, an adaptor assembly includes a lug body and an adaptor body. The adaptor body is coupled to, and in electrical communication with, the lug body. The lug body includes a cable passage, wherein said cable passage has a cross-sectional area corresponding to a cable of a first amperage. The adaptor body includes a conducting surface, wherein said conducting surface has a surface area corresponding to a conductor terminal end mating surface of a second amperage.
