Abstract

A secondary disconnect assembly for use with a circuit breaker moveable between a connected position and a disconnected position includes a first secondary disconnect apparatus and a second secondary disconnect apparatus. The first secondary disconnect apparatus includes a first coupling portion having at least one high speed communications connector. The second secondary disconnect apparatus includes a second coupling portion removably coupled to the first coupling portion. The second coupling portion includes at least one opening configured to receive the high speed communications connector when the circuit breaker is moved from the disconnected position to the connected position to enable high speed data transmission through the first coupling portion and the second coupling portion.

First claim

What is claimed is:

1. A secondary disconnect assembly for use with a circuit breaker moveable between a connected position and a disconnected position, said secondary disconnect assembly comprising:
a first secondary disconnect apparatus comprising:
a first coupling portion comprising a body portion integrally formed with said first secondary disconnect apparatus, wherein said body portion at least partially houses at least one high speed communications connector, said first coupling portion further comprising a cover coupled to said body portion, configured to restrict movement of said high speed communications connector; and
a first alignment feature comprising a first pair of angled ramp surfaces; and

a second secondary disconnect apparatus comprising:
a second alignment feature configured to couple to said first alignment feature when the circuit breaker is in the connected position, wherein said second alignment feature comprises a second pair of angled ramp surfaces configured to mate with said first pair of angled surfaces when the circuit breaker is in the connected position; and
a second coupling portion removably coupled to said first coupling portion, said second coupling portion comprising at least one opening configured to receive said high speed communications connector when the circuit breaker is moved from the disconnected position to the connected position to enable high speed data transmission through said first coupling portion and said second coupling portion.

2. The secondary disconnect assembly in accordance with claim 1 , wherein said second coupling portion comprises a body portion and at least one coupler at least partially housed within said body portion, said body portion integrally formed with said second secondary disconnect apparatus.

3. The secondary disconnect assembly in accordance with claim 2 , wherein said body portion comprises a first body opening and a second body opening, said coupler comprising a first coupler opening aligned with said first body opening and a second coupler opening aligned with said second body opening.

4. The secondary disconnect assembly in accordance with claim 3 , wherein said first body opening is oriented substantially perpendicular to said second body opening.

5. The secondary disconnect assembly in accordance with claim 3 , wherein said first body opening and said first coupler opening are configured to receive said high speed communications connector when the circuit breaker is in the connected position.

6. The secondary disconnect assembly in accordance with claim 2 , wherein said body portion comprises a wall having a slot defined therein and said coupler comprises a projection configured to engage said slot to facilitate coupling said coupler to said body portion.

7. A circuit breaker assembly comprising:
cassette;
a first secondary disconnect apparatus pivotally coupled to said cassette, said first secondary disconnect apparatus comprising a first coupling portion comprising:
at least one high speed communications connector;
a body portion integrally formed with said first secondary disconnect apparatus and configured to at least partially house said high speed communications connector; and
a cover coupled to said body portion, said cover configured to restrict movement of said high speed communications connector;

a circuit breaker removably coupled within said cassette, said circuit breaker moveable between a connected position and a disconnected position; and
a second secondary disconnect apparatus coupled to said circuit breaker, said second secondary disconnect apparatus comprising a second coupling portion removably coupled to said first coupling portion, said second coupling portion comprising at least one opening configured to receive said high speed communications connector when said circuit breaker is moved from the disconnected position to the connected position to enable high speed data transmission through said first coupling portion and said second coupling portion.

8. The circuit breaker assembly in accordance with claim 7 , wherein said second coupling portion comprises a body portion and at least one coupler at least partially housed within said body portion, said body portion integrally formed with said second secondary disconnect apparatus.

9. The circuit breaker assembly in accordance with claim 8 , wherein said body portion comprises a first body opening and a second body opening, said coupler comprising a first coupler opening aligned with said first body opening and a second coupler opening aligned with said second body opening, wherein said first body opening and said first coupler opening are configured to receive said high speed communications connector when said circuit breaker is in the connected position.

10. The circuit breaker assembly in accordance with claim 7 , wherein said first secondary disconnect apparatus comprises a first alignment feature and said second secondary disconnect apparatus comprises a second alignment feature configured to couple to said first alignment feature when the circuit breaker is in the connected position.

11. A method of assembling a circuit breaker assembly, said method comprising:
pivotally coupling a first secondary disconnect apparatus to a cassette, the first secondary disconnect apparatus including a first coupling portion including at least one high speed communications connector;
removably coupling a circuit breaker to the cassette, wherein the circuit breaker is moveable between a connected position and a disconnected position;
coupling a second secondary disconnect apparatus to the circuit breaker, the second secondary disconnect apparatus including a second coupling portion;
integrally forming a body portion of the second coupling portion with the second secondary disconnect apparatus, the body portion having a first body opening and a second body opening;
coupling a coupler to the body portion such that the body portion at least partially houses the coupler, the coupler having a first coupler opening and a second coupler opening;
aligning the first body opening with the first coupler opening and the second body opening with the second coupler opening; and
removably coupling the second coupling portion to the first coupling portion, wherein the second coupling portion includes at least one opening configured to receive the high speed communications connector when the circuit breaker is moved from the disconnected position to the connected position to enable high speed data transmission through the first coupling portion and the second coupling portion.

12. The method in accordance with claim 11 further comprising:
integrally forming a body portion of the first coupling portion with the first secondary disconnect apparatus; and
coupling a cover to the body portion of the first coupling portion such that the cover restricts movement of said high speed communications connector.

13. The method in accordance with claim 11 further comprising inserting the high speed communications connector into the first body opening and the first coupler opening as the circuit breaker moves from the disconnected position to the connected position.

14. The method in accordance with claim 11 further comprising removably coupling a first alignment feature of the first secondary disconnect apparatus with a second alignment feature of the secondary disconnect apparatus when the circuit breaker is in the connected position.
