Abstract:
A load break interrupter, comprising:(a) a case having a housing and a cover attached to said housing and forming an interior chamber with said housing between respective main walls of said housing and said cover, said case being split diagonally so as to provide said cover and said housing;(b) an arc-suppressing tube attached on and extending outwardly from said case;(c) a shunt circuit rod slidably supported in said arc-suppressing tube for making and breaking a shunt circuit inside said arc-suppressing tube upon sliding of said rod into and from said arc-suppressing tube, said breaking of said shunt circuit sometimes causing an arcing to occur inside said arc-suppressing tube; and(d) a shunt circuit break actuating mechanism disposed in said interior chamber of said case and coupled with said rod such that tripping of said actuating mechanism from a shunt circuit-defining position to a shunt circuit-breaking position causes said rod to at least partially extend into said case from said arc-suppressing tube thereby breaking the shunt circuit such that any arcing that occurs inside said arc-suppressing tube upon breaking of said shunt circuit inside said arc-suppressing tube is confined and suppressed inside said arc-suppressing tube by said shunt circuit rod, said housing and cover of said case havingrespective component mounting elements formed thereon which extend inwardly from said main walls of said housing and cover into said interior chamber of said case and cooperate together so as to mount and retain components of said shunt circuit break actuating mechanism in operative relationship with one another between said housing and cover of said case, andrespective guide elements formed thereon which extend inwardly from said main walls of said housing and cover into said interior chamber of said case and cooperate together to guide movement of said shunt circuit rod in said interior chamber between said housing and cover of said case.
