Abstract
An enclosure for a circuit breaker that includes a particle trap that is integrated into at least one foot of the enclosure. The enclosure can be configured to house a circuit interrupter and seal a dielectric insulating medium within an interior region of the enclosure. The particle trap can include an opening that extends through at least an inner side of a wall of the enclosure and into an adjacent foot such that the opening is in fluid communication with the interior region of the enclosure. Additionally, the opening of the particle trap can radially extend within both the wall of the enclosure and the foot between a first side and a second side of the particle trap.
Claims19
An apparatus comprising:
- an enclosure having a wall and a plurality of feet, the wall having an inner side that generally defines an interior region of the enclosure, the plurality of feet extending outwardly from, and radially about, at least a portion of the wall;
- and
- a particle trap having an opening in at least one foot of the plurality of feet that (i) outwardly extends between a first end and a second end of the particle trap, and (ii) radially extends between a first side and a second side of the particle trap, wherein the first end of the particle trap is at the inner side of the wall of the enclosure and the second end of the particle trap is within the at least one foot,
- wherein the plurality of feet each include a plurality of mounting holes.
An apparatus comprising:
- an enclosure having a wall and a plurality of feet, the wall having an inner side that generally defines an interior region of the enclosure, the plurality of feet extending outwardly from, and radially about, at least a portion of the wall;
- and
- wherein each foot of the plurality of feet includes a particle trap, each of the particle traps having an opening that (i) extends through the wall of the enclosure and into the foot such that the opening is in fluid communication with the interior region of the enclosure, and (ii) radially extends within both the wall and the foot between a first side and a second side of the particle trap,
- wherein the plurality of feet each include a plurality of mounting holes.
A circuit breaker comprising:
- at least one pole assembly having a first electrical conductor, a second electrical conductor,
- an enclosure, and a circuit interrupter,
- wherein the enclosure includes a wall and a plurality of feet, the wall having an inner side that defines an interior region of the enclosure,
- wherein the circuit interrupter is housed within the interior region of the enclosure, and
- wherein each foot of the plurality of feet includes a particle trap, the particle trap having an opening that (i) extends through the wall of the enclosure and into the foot such that the opening is in fluid communication with the interior region of the enclosure, and (ii) radially extends within both the wall and the foot between a first side and a second side of the particle trap,
- wherein the plurality of feet each include a plurality of mounting holes.
