Definitions

  • This invention relates to circuit breakers and more particularly to contact means and to a bumper for circuit breakers.
  • Another object of the invention is to provide a high-speed circuit breaker having relatively movable contact means embodying improved means for deceleratng the moving contact and preventing rebound of the moving contact upon closure of said contact means.
  • the circuit breaker comprises generally a back plate l l upon which the breaker mechanism is mounted, stationary contact means I3, movable contact means I5, closing mechanism indicated generally at I1 and trip-means indicated generally at I9.
  • the contact blades 25 engage opposite sides of the stationary contact I3.
  • the Contact blades 25 are provided with facing elongated contacts 'I9 disposed along their leading edges for engaging the stationary Contact I3 with a wiping action.
  • the Contact blades 25 are. spaced apart by means of a spacer SI disposed therebetween and mounted on a bolt 83 which extends through openings in the switch blades.
  • the bolt 83 is provided with a head 85 on one end and the. other end threadedly engages a nut tl'. Normal contact pressure is provided by means of aspring 89 compressed between Athe head 85 of the bolt 33 and ⁇ the. adjacent contact blade 2 5.
