A power connector () is provided for connecting a drawout circuit breaker to a conductive bus bar. The power connector () is formed as a unitary body having a first end and a second end opposite the first end. The first end has a circuit breaker terminal () to connect to the drawout circuit breaker through the clusters. The second end has a bus bar terminal () to connect to the conductive bus bar. The bus bar terminal () may have a pair of extending arms (), which form a U-shape profile. A conductive bus bar can be connected between the pair of extending arms () on one or both sides to the bus bar terminal ().

An interrupter module for a molded case circuit breaker has a floating antifriction disc between the module casings and the blade carrier which overlays the blade carrier with rim walls of the disc. The rim walls are located at segments of the disc containing the drive pins of the module. If gases from circuit interruption expand the interrupter module sides and force the disc away from the blade carrier, the rim walls remain over the blade carrier and protect the drive pins from contaminants carried by the gases.

A lug having an integrated shoe for fastening the lug to a conductor and a terminal of a circuit breaker. The lug includes a housing and a cavity in the housing configured to receive the electrical conductor. The shoe has a hinge connecting the shoe to an inner wall of the housing. A slot is located adjacent to the shoe such that the shoe is positioned between the cavity and the slot, which receives the terminal. A hole in the housing receives a fastener that extends into the cavity. A force applied to the fastener urges the conductor to clamp against the shoe to cause it to deflect about the hinge and to press against the terminal to hold the lug in a secure relationship relative to the terminal and to hold the conductor in a secure relationship relative to the lug.
