Edmundson Industrial supplies, sources, and stocks industrial electrical equipment across all major manufacturers: from current production lines to discontinued legacy brands that standard distributors no longer support. If you need it for a current build or a plant that runs on 30-year-old equipment, send us a part number and we'll check availability.
Industrial facilities don't run on a single manufacturer's equipment. A plant built over decades has Eaton breakers next to old Westinghouse switchgear, Allen-Bradley controls driving Baldor motors, and ABB drives sitting alongside equipment that predates half the brands currently in the market. Edmundson Industrial is equipped to supply across all of it.
For current production lines (Eaton, Square D, Siemens, ABB, Allen-Bradley, and others) we supply directly from active distribution channels. For discontinued and legacy brands (Westinghouse, ITE, Federal Pacific, Sylvania, Gould, and others) we source through surplus, reconditioned, and new-old-stock inventory channels that most standard distributors don't maintain access to.
The brands listed on this page represent manufacturers we handle most frequently. If the brand or part number you need isn't listed, send it anyway. Our sourcing capability extends beyond what's covered here.

Edmundson Industrial's relationship with manufacturers varies by brand and product line. Here's how our supply and sourcing model works across current and legacy equipment.
For active manufacturers (Eaton, Square D, Siemens, ABB, Allen-Bradley) we supply through active distribution and supply channels. Standard lead times apply for in-stock and non-stocked items. Part numbers, catalog numbers, or model designations are the fastest path to a quote.
For discontinued, legacy, and obsolete brands and product lines, we source through surplus, new-old-stock, and reconditioned inventory channels. Condition is always stated clearly (new, surplus, reconditioned, or used) with every quote. Original part numbers, nameplate data, or photos help us identify the correct item.
When an exact OEM replacement is unavailable, we can advise on compatible alternatives depending on the application. This requires understanding the electrical characteristics, mounting requirements, and application context. Provide as much detail as you have and we'll identify the options.
