    Patent number: 10224163
    Abstract: A circuit breaker housing assembly is disclosed. The housing (47) includes a first housing piece (14) defining a first interior surface (52) including a first mating surface (152), and a second housing piece (60) defining a second interior surface (62) including a second mating surface (260) which is opposingly coupled to the first mating surface to define a seam (202) therebetween. An adhesive material (201) is disposed between the corresponding first and second mating surfaces along the seam. A moveable contact is disposed in the housing and is selectively moveable with respect to a corresponding stationary contact. The first and second interior surfaces (52,62) further cooperatively define a first recess (120) therebetween, and the moveable contact assembly is disposed in said first recess.
