Phasenstromabtrennung für einen Schalter

An industrial rated molded case circuit breaker is fitted with a phase barrier and a phase insulation cap at the line end thereof to redirect the arc exhaust gases exiting from the line end and to prevent an electric circuit between the different phases of a multiphase electric power distribution system. The Y-shaped phase barrier eliminates the need to provide additional insulation to the line end conductors. The phase insulation cap provides inexpensive and reusable means for isolating mounting screws from the line end conductors.
