April 30, 2017. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesMulti-pole ground fault circuit breaker Molded case circuit breaker having a thermoplastic cover Molded case circuit breaker exhaust barrier Bus cover and lug cover for a molded case circuit breaker Ground fault module conductors and base therefor Two-pole compartmentalized ground fault miniature circuit breaker with increased current rating Circuit breaker with distribution lug terminal having trapped insulator Patent #: 5488337 InventorsApplicationNo. 846397 filed on 04/30/1997US Classes:335/8, Multipole or polyphase335/202With housing or support meansExaminersPrimary: Donovan, LincolnAttorney, Agent or FirmInternational ClassH01H 075/00AbstractA miniature molded case circuit breaker is adapted for use with load conductors having ring lug terminations by extending the circuit breaker load terminal conductor through the terminal recess and beyond the molded housing. An adapter includes an insulative shield member having an open slot in which the load terminal conductor terminates for connection to the ring lug on a load conductor. The adapter further includes an insulator which seats snugly in the terminal recess of the housing and through which the load terminal conductor extends. A bifurcated neck on the insulator extends through an opening into the shield member. The shield member is secured to the circuit breaker by projections which snap into grooves in the neck portion of the insulator and a cantilevered resilient finger which engages a catch on the molded housing.Field of SearchAutomatic circuit-interrupting devices (e.g., circuit-protective devices)Multipole or polyphase With individual latch or trip means in each leg With common latch or trip means With adjustable, replaceable or interchangeable structural features With housing or support means Cases and bases Unitary switch mounted in handle or handgrip Surface With flexible mounting means Panel Outlet box Pendant With lamp socket Frangible element Vibration dampening means Dust, dirt, or moisture excluding Seal for push button actuator Seal for rocker or lever actuator Split housing With shield Electrical shield | |
