Abstract

A reversible fuse support block includes a molding, a terminal, and a fuser interface. The molding may be installed within a housing in a first position and a second position, wherein the second position is rotated 180 degrees relative to the first position. The terminal couples to the molding and includes a plurality of apertures disposed in a pattern. The fuse interface receives a first end of a fuse. The fuse interface couples to the terminal in a first arrangement and a second arrangement such that when the fuse interface is installed in the first arrangement and the molding is installed in the first position, the fuse interface is disposed in substantially the same position relative to a corresponding fuse interface on a fuse support block as when the fuse interface is installed in the second arrangement and the molding is installed in the second position.

First claim

The invention claimed is:

1. A reversible fuse support block for a switch disconnect assembly, comprising:
a molding configured to be installed within a housing of the switch disconnect assembly in a first position and a second position, wherein the second position is rotated 180 degrees relative to the first position;
a first terminal configured to couple to the molding, wherein the first terminal comprises:
a plurality of apertures disposed in a pattern; and
first and second notches that, in an installed configuration, receive first and second respective legs of a first connection point; and

a first fuse interface configured to receive a first end of a fuse, wherein the first fuse interface is configured to couple to the first terminal in a first arrangement and a second arrangement such that when the first fuse interface is installed in the first arrangement and the molding is installed in the first position, the first fuse interface is disposed in substantially the same position relative to a second fuse interface on a fuse block of the switch disconnect assembly positioned within the housing, opposite the fuse support block, as when the first fuse interface is installed in the second arrangement and the molding is installed in the second position.

2. The reversible fuse support block of claim 1 , wherein the fuse support block is configured to receive an electrical line, wherein the electrical line is configured to electrically couple the first terminal to a power supply, and wherein the electrical line is coupled to the first terminal via the first connection point.

3. The reversible fuse support block of claim 1 , wherein the disconnect switch assembly is rated for 30 Amps.

4. The reversible fuse support block of claim 1 , wherein, when the molding is installed in the second position, an electrical line extends from the fuse support block, beneath the fuse extending between the fuse support block and the fuse block.

5. The reversible fuse support block of claim 1 , wherein the molding comprises:
a first terminal block configured to receive the first terminal;
a second terminal block configured to receive a second terminal; and
a bridge extending between the first terminal block and the second terminal block.

6. The reversible fuse support block of claim 5 , wherein the bridge comprises:
a first aperture configured to receive a fastener when the molding is installed in the first position; and
a second aperture configured to receive the fastener when the molding is installed in the second position.

7. The reversible fuse support block of claim 5 , comprising the second terminal, wherein the second terminal comprises:
a second plurality of apertures disposed in the pattern; and
second and third notches that, in an installed configuration, receive third and fourth respective legs of a second connection point.

8. A method of installing a fuse support block for a switch disconnect assembly, comprising:
coupling a terminal to a molding, wherein the molding is configured to be installed within a housing of the switch disconnect assembly in a first position and a second position, and wherein the terminal comprises:
a plurality of apertures disposed in a pattern; and
first and second notches that, in an installed configuration, receive first and second respective legs of a connection point;

coupling a first fuse interface to the terminal, wherein the first fuse interface is configured to receive a first end of a fuse, wherein the first fuse interface is configured to couple to the terminal in a first arrangement and a second arrangement such that when the first fuse interface is installed in the first arrangement and the molding is installed in the first position, the first fuse interface is disposed in substantially the same position relative to a second fuse interface on a fuse block of the switch disconnect assembly positioned within the housing, opposite the fuse support block, as when the first fuse interface is installed in the second arrangement and the molding is installed in the second position; and
installing the molding in the housing.

9. The method of claim 8 , wherein the molding is installed in the first position.

10. The method of claim 8 , wherein the molding is installed in the second position.

11. The method of claim 8 , comprising coupling an electrical line to the terminal via the connection point, wherein the electrical line is configured to electrically couple the terminal to a power supply.

12. The method of claim 8 , wherein the disconnect switch assembly is rated for 30 Amps.

13. An industrial automation system, comprising:
a power supply;
an industrial automation motor starter configured to receive power from the power supply;
a disconnect switch assembly configured to electrically couple the power supply to the industrial automation motor starter, the disconnect switch assembly comprising:
a housing;
a fuse block disposed within the housing, the fuse block comprising a first fuse interface configured to receive a first end of a fuse;
a reversible fuse support block disposed within the housing, opposite the fuse block, the reversible fuse support block comprising:
a molding configured to be installed within the housing in a first position and a second position, wherein the second position is rotated 180 degrees relative to the first position;
a first terminal configured to couple to the molding, wherein the first terminal comprises:
a plurality of apertures disposed in a pattern; and
first and second notches that, in an installed configuration, receive first and second respective legs of a first connection point; and

a second fuse interface configured to receive a second end of the fuse, wherein the second fuse interface is configured to couple to the first terminal in a first arrangement and a second arrangement such that when the second fuse interface is installed in the first arrangement and the molding is installed in the first position, the second fuse interface is disposed in substantially the same position relative to the first fuse interface as when the second fuse interface is installed in the second arrangement and the molding is installed in the second position.

14. The industrial automation system of claim 13 , wherein the molding of the reversible fuse support block comprises:
a first terminal block configured to receive the first terminal;
a second terminal block configured to receive a second terminal; and
a bridge extending between the first terminal block and the second terminal block.

15. The industrial automation system of claim 14 , wherein the bridge comprises:
a first aperture configured to receive a fastener when the molding is installed in the first position; and
a second aperture configured to receive the fastener when the molding is installed in the second position.

16. The industrial automation system of claim 14 , wherein the reversible fuse support block comprises the second terminal, wherein the second terminal comprises:
a second plurality of apertures disposed in the pattern; and
second and third notches that, in an installed configuration, receive third and fourth respective legs of a second connection point.

17. The industrial automation system of claim 13 , comprising an electrical line extending from the fuse support block toward the fuse block, beneath the fuse extending between the fuse support block and the fuse block when the molding is installed in the second position.

18. The industrial automation system of claim 13 , comprising an electric
