  • Circuit breaker mechanism for a contact system
    Patent number: 6369340
    Abstract: A rotary contact circuit breaker employs a crank to couple a switching mechanism to the rotary contact pole structure. The use of a crank allows for the mechanism and pole structure the individually optimized without effecting the performance of the other. In particular the crank allows for a mechanism that is able to achieve maximum torque delivery to the pole structure.

  • Circuit breaker arc exhaust baffle with variable aperture
    Patent number: 6222147
    Abstract: An improved exhaust baffle for a circuit protective device such as a circuit breaker utilizes material having elastomeric characteristics to provide for variable apertures where the cross-sectional opening of the apertures is dependent on the pressure gradient across the exhaust baffle, thereby effectively controlling arc pressure and arc effluent during short circuit interruption. Fabrication of the exhaust baffle with geometric symmetry about one or more axes or planes also facilitates assembly during product construction.
