Westinghouse DB and DHP, ITE K-Line, Federal Pacific Stab-Lok, Sylvania, Gould, GE AK series, and others: sourced through surplus, new-old-stock, and specialty inventory channels. This page covers discontinued lines only. For current-production breakers, see our circuit breakers page.
Industrial facilities regularly face a specific problem: equipment installed decades ago requires replacement parts that manufacturers no longer produce. For circuit breakers, this often means a breaker frame that was absorbed by a later acquisition, a series that was redesigned without backward compatibility, or a manufacturer that simply closed. Standard distributors cannot help, because the part is not in their current catalog.
Edmundson Industrial sources discontinued and obsolete circuit breakers through surplus networks, new-old-stock inventory, and specialty channels. We can check availability on a catalog number and come back with what's out there, in what condition, and at what price. If the part doesn't exist in the market, we'll say so directly.
These manufacturers either no longer exist or have been fully absorbed into current brands without catalog compatibility. Parts must come from surplus or NOS inventory.
Air circuit breakers, draw-out power breakers, and MCCBs from the Westinghouse line. The DB and DHP series remain in service in older switchgear installations. Eaton absorbed the Westinghouse electrical line but does not produce replacement parts for these frames.
ITE circuit breakers including K-Line draw-out LVPCBs, J-frame and K-frame MCCBs. Siemens acquired ITE but the legacy ITE series are not catalog-compatible with current Siemens product lines. Sourced through surplus and NOS channels.
Federal Pacific Stab-Lok breakers remain in a large number of older installations. Replacement sourcing is available through surplus channels. Condition is disclosed on every quote. We do not certify or warrant these units beyond the condition description provided.
Sylvania QFP, QBL, and QP series breakers are encountered in older industrial and commercial installations. Zinsco breakers appear in similar vintage equipment. Both are sourced through surplus; availability varies significantly by model and ampere rating.
GE air frame circuit breakers (AK, AKU, AKD) remain in service in older switchgear installations. These draw-out power breakers are long discontinued but still actively sought for maintenance of legacy gear. Sourced through specialty inventory.
Gould breakers (including products absorbed from their earlier acquisitions) and Allis-Chalmers distribution breakers are among the harder-to-find legacy lines. Availability is limited. Send the catalog number and we'll check what's in the market.
Sourcing a discontinued circuit breaker is not like placing a standard order. The supply exists in a secondary market that has no centralized inventory, no published pricing, and no guaranteed availability. What you get depends on what happened to exist in a warehouse, a plant shutdown lot, or an electrical surplus dealer's stock at the time you're looking.
Some series are relatively easy to find because they were widely installed and a lot of equipment ended up on the surplus market. Others are nearly impossible because production volumes were low, the equipment was well-maintained and stayed in service, or the surplus market simply ran dry years ago. We'll tell you which situation you're in.
We also will not misrepresent condition. A unit described as "surplus, unverified" is exactly that. If we can confirm testing, we'll say so. If we can't, we won't pretend otherwise. For facilities that need breakers that are going back into live service, that distinction matters.
Practical note: If the catalog number is for a breaker in a frame that physically cannot be matched with a modern unit, surplus or NOS is your only path. If there is a modern equivalent that fits the application (frame dimensions, interrupting rating, voltage), we can often identify it and quote both options.
The original catalog number or part number is the fastest identification path. If you only have a nameplate description or a photo of the existing breaker, send that. We can usually identify the part from nameplate data.
Ampere rating, voltage rating, pole count, interrupting rating (if known), and trip type. For draw-out breakers, the racking mechanism style and frame designation help narrow the search immediately.
We check our sourcing contacts and respond with what's available, what condition it's in, and what it costs. If nothing is in the market, we'll say so and can discuss alternatives if any exist.
Every quote includes the condition description: new, new-old-stock, surplus unverified, or reconditioned with details. No ambiguous language about units going into live electrical systems.
