Abstract
In a circuit breaker (1) with a two piece molded housing (30) with a longitudinal mold parting line (33), a retainer (48) is mounted to the housing and has a bore (50) extending parallel to the parting plane for receiving a screw (58) which mounts a filler plate (52) covering open areas adjacent the breaker.
Claims11
A circuit breaker mounted to support structure in a panelboard, said breaker comprising a molded housing having a frontside with a user-engageable pivoted operating handle extending through said frontside and moveable in an arc in a given plane, said housing being formed by a pair of molded housing sections joined along a parting line lying in a parting plane parallel to said given plane of handle movement along said arc, said frontside of said housing lying in a plane perpendicular to said parting plane, a retainer mounted to a pre-assembled said housing and having a bore extending parallel to said parting plane and perpendicularly to said frontside of said housing, a filler plate mounted to said housing by removeable attachment means extending into said bore, said filler plate extending only from one side of said housing and parallel to said frontside of said housing to cover open areas adjacent said breaker, wherein said retainer comprises a central portion defining said bore, and a pair of arms each extending from said central portion to a respective one of said housing sections, and further wherein said housing includes slot means, and said retainer includes snap-in detent means engaging and nesting in said slot means in snap-in relation.
A circuit breaker mounted to support structure in a panelboard, said breaker comprising a molded housing having a frontside with a user-engageable pivoted operating handle extending through said frontside and moveable in an arc in a given plane, said housing being formed by a pair of molded housing sections joined along a parting line lying in a parting plane parallel to said given plane of handle movement along said arc, said frontside of said housing lying in a plane perpendicular to said parting plane, a retainer mounted to said housing and having a bore extending parallel to said parting plane and perpendicularly to said frontside of said housing, a filler plate mounted to said housing by removeable attachment means extending into said bore, said filler plate extending parallel to said frontside of said housing to cover open areas adjacent said breaker,
- wherein said housing includes slot means, and said retainer includes snap-in detent means engaging and nesting in said slot means in snap-in relation,
- wherein said slot means comprises a slot in each of said housing sections, and wherein said detent means of said retainer comprises a pair of flexible arms each having a stop shoulder, each arm engaging a respective said slot in the respective said housing section and flexing until said shoulder engages said slot to lock said retainer to said housing.
A circuit breaker mounted to support structure in a panelboard, said breaker comprising a molded housing, said housing having a vertical front wall with a user-engageable pivoted operating handle extending forwardly through said front wall and moveable in a horizontal arc, said housing having a vertical back wall, said housing having a vertical left side wall, said housing having a vertical right side wall, said housing having a horizontal top wall, said housing having a horizontal bottom wall, said housing having an upper flange extending horizontally rightwardly from said top wall beyond said right side wall, said housing having a lower flange extending horizontally rightwardly from said bottom wall beyond said right side wall, said housing being formed by a pair of molded housing sections joined along a horizontal parting line such that said housing is comprised of an upper housing section and a lower housing section, said upper flange being part of said upper housing section, said lower flange being part of said lower housing section, a retainer mounted between said flanges and having a bore extending horizontally rearwardly and parallel to said right side wall, a vertical filler plate engaging the front edges of said flanges and mounted thereto by removable attachment means extending rearwardly into said bore, said filler plate extending rightwardly from said front wall and covering the area between said flanges.
