Abstract:
An electrical switching apparatus includes a body and a display apparatus. The body has a housing, a handle partially extending through the housing, separable contacts located within the housing, an operating mechanism structured to open and close the separable contacts, a main printed circuit board located within the housing, and a number of electrical rating settings associated with the main printed circuit board. Each of the number of electrical rating settings has a magnitude. The display apparatus is electrically connected to the main printed circuit board and is structured to display the magnitude of at least one of the number of electrical rating settings.
Abstract:
Circuit breakers include an arc chamber and an arc chute comprising a plurality of arc plates in the arc chamber. The circuit breakers also include a line conductor assembly with at least one arc runner attached to a line conductor in the arc chamber. The arc runner can extend below but adjacent to a bottom arc plate to thereby guide a respective arc into the arc chute.
