Abstract

A module assembly is for an electrical switching apparatus assembly. The electrical switching apparatus assembly includes an electrical switching apparatus having a housing, a pair of separable contacts located internal with respect to the housing, and a shunt trip device for tripping open the pair of separable contacts. The module assembly includes a mounting member structured to be coupled to the housing, and an internet of things (IOT) module coupled to the mounting member. The IOT module is structured to be electrically connected to the shunt trip device in order to trip open the pair of separable contacts.

First claim

What is claimed is:

1. A module assembly for an electrical switching apparatus assembly, said electrical switching apparatus assembly comprising an electrical switching apparatus having a housing, a pair of separable contacts disposed internal with respect to said housing, and a shunt trip device for tripping open said pair of separable contacts, said module assembly comprising:
a mounting member mounted to said housing; and
an IOT module coupled to said mounting member,
wherein said IOT module is electrically connected to said shunt trip device in order to trip open said pair of separable contacts; wherein said mounting member comprises a floor portion and a wall portion extending from said floor portion; and wherein said IOT module is disposed internal with respect to said wall portion.

2. The module assembly of claim 1 wherein said mounting member further comprises a number of clip portions extending from at least one of said floor portion and said wall portion; and wherein said number of clip portions are mounted to said housing.

3. The module assembly of claim 2 wherein each of said number of clip portions comprises a first leg and a second leg disposed opposite said first leg; and wherein said first leg and said second leg are biased toward engagement with said housing.

4. The module assembly of claim 2 wherein said number of clip portions comprises a first clip portion and a second clip portion; wherein said mounting member further comprises a securing portion extending from said first clip portion to said second clip portion; and wherein said securing portion is mounted to said housing.

5. The module assembly of claim 4 wherein said securing portion comprises a first planar portion, a second planar portion disposed opposite said first planar portion, and a third planar portion extending from said first planar portion to said second planar portion and being disposed generally perpendicular to said first planar portion and said second planar portion; wherein said first planar portion extends from said first clip portion; and wherein said second planar portion extends from said second clip portion.

6. The module assembly of claim 5 wherein said mounting member further comprises a support portion extending from said wall portion and said third planar portion.

7. The module assembly of claim 5 wherein said wall portion comprises an extension portion and a body portion each extending from said floor portion in opposing directions; wherein said IOT module is disposed internal with respect to said body portion; and wherein said mounting member further comprises a number of support portions extending from said floor portion and said extension portion.

8. The module assembly of claim 2 wherein said floor portion is generally triangular-shaped; and wherein said IOT module is shaped according to said floor portion.

9. The module assembly of claim 2 wherein said floor portion is generally rectangular-shaped; and wherein said IOT module is shaped according to said floor portion.

10. An electrical switching apparatus assembly comprising:
an electrical switching apparatus having a housing, a pair of separable contacts disposed internal with respect to said housing, and a shunt trip device for tripping open said pair of separable contacts; and
a module assembly comprising:
a mounting member coupled to said housing, and
an IOT module coupled to said mounting member,

wherein said IOT module is electrically connected to said shunt trip device in order to trip open said pair of separable contacts; wherein said mounting member comprises a floor portion, a wall portion extending from said floor portion, and a securing portion extending from at least one of said floor portion and said wall portion; wherein said IOT module is disposed internal with respect to said wall portion; and wherein said securing portion is mounted to said housing.

11. The electrical switching apparatus assembly of claim 10 wherein said housing comprises a planar portion having a slot; wherein said securing portion comprises a planar portion having a slot; wherein said planar portion of said securing portion overlays and is generally parallel with said planar portion of said housing; and wherein the slot of said housing is aligned with the slot of said securing portion in order to provide a pathway therethrough.

12. The electrical switching apparatus assembly of claim 11 wherein said electrical switching apparatus is a main circuit breaker.

13. The electrical switching apparatus assembly of claim 10 wherein said mounting member further comprises a number of clip portions extending from at least one of said floor portion and said wall portion; and wherein said number of clip portions are mounted to said housing.

14. The electrical switching apparatus assembly of claim 13 wherein each of said number of clip portions comprises a first leg and a second leg disposed opposite said first leg; and wherein said first leg and said second leg engage said housing and are biased toward engagement with said housing.

15. The electrical switching apparatus assembly of claim 13 wherein said housing comprises a first terminal portion and a second terminal portion each having an opening receiving a conductor; wherein said number of clip portions comprises a first clip portion and a second clip portion; wherein said first clip portion is mounted to said first terminal portion; and wherein said second clip portion is mounted to said second terminal portion.

16. The electrical switching apparatus assembly of claim 10 wherein said housing comprises a first terminal portion and a second terminal portion each having an opening receiving a conductor; wherein each of said first terminal portion and said second terminal portion comprises a first end portion and a second end portion opposite said first end portion such that the opening is disposed therebetween; wherein said floor portion extends from said first end portion of said first terminal portion to said first end portion of said second terminal portion; and wherein said wall portion comprises a body portion extending from said floor portion away from said first terminal portion and said second terminal portion.

17. The electrical switching apparatus assembly of claim 10 wherein said housing has a number of slots through which said IOT module is electrically connected to said shunt trip device.

18. A method of operating an electrical switching apparatus assembly comprising the steps of:
providing an electrical switching apparatus having a housing, a pair of separable contacts disposed internal with respect to said housing, and a shunt trip device for tripping open said pair of separable contacts;
providing a module assembly comprising a mounting member mounted to said housing, and an IOT module coupled to said mounting member, said mounting member comprising a floor portion and a wall portion extending from said floor portion, said IOT module being disposed internal with respect to said wall portion;
electrically connecting said IOT module to said shunt trip device; and
sending a signal to said IOT module with a wireless communication device in order to trip open said pair of separable contacts.
