摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing, and an operating mechanism disposed in the housing and interconnected with the contacts. A trip mechanism is disposed in the housing and includes a rotatable trip bar assembly that, when selectively rotated, generates a tripping operation that causes the contacts to open. The trip mechanism further includes an automatic trip assembly for selectively rotating the trip bar assembly upon a predetermined current threshold. The automatic trip assembly includes a magnetic yoke having two arms with a pivot support on the top of each. Each of the pivot supports includes a pivot surface, and one of the pivot supports includes a rear retaining protrusion adjacent its pivot surface. The other of the pivot supports includes a front retaining member adjacent its pivot surface. The automatic trip assembly further includes an armature having pivot portions positioned on the pivot surfaces which provides for rotation of the armature between a first position away from the arms and a second position closer to the arms. A magnetic field is generated upon the predetermined current threshold which causes the armature to rotate from the first position to the second position and to rotate the trip bar assembly. One of the pivot supports also includes a downwardly facing stop. The downwardly facing stop is positioned to abut the armature when the armature is rotated away from the arms, thereby defining the first position.

摘要： A circuit interrupter including a housing having a cover connected to a base, separable main contacts within the housing, and an operating mechanism within the housing and interconnected with the contacts. A trip mechanism is disposed within the housing and includes a rotatable trip bar assembly that, when selectively rotated, generates a tripping operation. The trip mechanism includes a dual-purpose trip actuator biased upwards and positioned for vertical movement within the housing and having a top portion extending through the cover. The actuator includes a push-to-trip member and an interlock trip member. The trip bar assembly includes a multi-purpose trip member having a push-to-trip actuating region, an interlock trip actuating region, and an accessory trip actuating region. The push-to-trip member contacts the push-to-trip actuating region when the top portion is depressed, causing the trip bar assembly to rotate. The interlock trip member contacts the interlock trip actuating region when the cover is removed from the base, causing the trip bar assembly to rotate. The accessory trip actuating region is positioned to be contacted by the tripping member of the external accessory device and thereby cause rotation of the trip bar assembly.

摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing, and an operating mechanism disposed in the housing and interconnected with the contacts. The housing has a cover securable to a base, with the cover including a downwardly-facing abutment portion. An electrical terminal is releasably disposed within the base and has a tab that abuttingly engages the abutment portion of the cover when the cover is secured to the base. The base also includes channels formed in the sides of the base, and the electrical terminal includes sides that insert into the channels and that include rib portions that frictionally engage the channels upon insertion. The base also includes tapered sides, with the electrical terminal sides being tapered in order to follow or mirror the tapered sides of the base.
