Molded case circuit breakers, low voltage power circuit breakers, fuses, trip units, and accessories: in current production and discontinued lines. Edmundson Industrial supplies active product lines and sources hard-to-find, obsolete, and discontinued breakers across all major manufacturers. If the catalog shows it as discontinued, send us the part number.
Edmundson Industrial supplies circuit breakers across two distinct channels. For current production breakers (Eaton, Square D, Siemens, ABB, General Electric) we supply through active distribution. For discontinued, obsolete, and hard-to-find breakers, we source through surplus and specialty inventory channels that standard distributors no longer maintain access to.
Industrial facilities often run equipment that requires breakers from lines long since discontinued. When a facility needs a replacement MCCB in a frame size or interrupting rating that no longer exists in current product lines, or when legacy switchgear requires a draw-out breaker from a manufacturer that stopped production decades ago, Edmundson Industrial provides an alternative supply path.
Circuit breaker applications span a wide range of current ratings, interrupting capacities, and mounting configurations. These are the categories we handle most frequently.
The most common circuit breaker type in industrial applications. Molded case breakers span frame sizes from 15A through 3000A+ in thermal-magnetic, electronic trip, and adjustable configurations.
Draw-out and fixed LVPCBs for switchgear applications. Larger frame sizes, higher interrupting ratings, and true short-time withstand ratings for use in main and tie breaker applications.
Trip unit replacements and breaker accessories, often needed when a breaker frame is serviceable but the trip unit has failed or needs upgrading without replacing the entire breaker assembly.
Current-limiting and non-current-limiting fuses for motor branch circuits, feeder protection, and equipment protection applications. Class H, J, K, L, RK1, and RK5 fuse types.
Older air frame circuit breakers (ACBs) remain in service in legacy industrial and utility installations. These are among the most frequently requested breakers for sourcing, long discontinued but still in active service.
Miniature circuit breakers, supplementary protectors, and branch circuit breakers for control panel, automation, and secondary distribution applications. DIN rail and panel-mount configurations.
Current production lines supplied through active distribution; discontinued and legacy brands sourced through surplus and specialty inventory channels.
Full Eaton circuit breaker lineup including Magnum DS, Series C, EG/HFD/HJD/HKD/JD frame MCCBs, and legacy Cutler-Hammer product lines. Eaton also inherited the Westinghouse breaker line through acquisition.
Powerpact, I-Line, QO, and Masterpact families. One of the most widely installed breaker brands in U.S. industrial facilities. Current production and legacy I-Line product lines.
Sentron, BQD, BQ, and WL switchgear breaker families. Siemens absorbed the ITE and Gould breaker lines through acquisition, legacy ITE and Gould breakers sourced through specialty inventory.
SACE Emax, SACE Tmax, Formula, and S200/S800 families for industrial power distribution. Legacy BBC breaker series sourced through surplus inventory channels.
Record Plus, PowerBreaker, THQB, THHQB, and legacy AK/AKR power circuit breaker series. GE LVPCBs remain in service in older switchgear installations across industrial facilities.
Westinghouse DB/DHP breakers, ITE draw-out and K-frame MCCBs, Sylvania QFP and QBL series, Federal Pacific Stab-Lok, Gould, and other discontinued brands, sourced as available.
Industrial facilities run on equipment that was installed decades ago, and that equipment requires breakers that may no longer be in active production. Standard distributors can only sell what's currently in the catalog. When a part number comes back "discontinued" or "no longer available," Edmundson Industrial provides an alternative path.
We source discontinued and obsolete circuit breakers through surplus, new-old-stock, and refurbished inventory channels. Condition is always disclosed clearly. If we can locate it, we'll quote it. If we can't, we'll tell you directly, and we can often identify a compatible modern replacement depending on the application.
The more information you provide, the faster we can check availability. These are the data points that help most:
Don't have all of this? Send what you have, even a photo of the existing breaker nameplate gives us most of what we need to identify the unit and check for availability.
Submit a RequestFor current-production breakers, the Eaton, Square D, Siemens, ABB, or GE catalog number is the fastest path. For discontinued breakers, the original catalog number, part number, or nameplate data starts the search.
Current lines are checked against active supply channels. Discontinued parts are checked against surplus, new-old-stock, and reconditioned inventory. We'll respond with what's available, in what condition, and at what price.
Every quote includes condition (new, surplus, reconditioned) and lead time. For sourced units, we'll describe the condition clearly: not just "used" but the specific state of the unit as confirmed by the supplier or our own inspection.
Approved quotes proceed to order. In-stock items ship from Houston, TX. Special-order and sourced items ship when received. We communicate on ship dates and provide tracking.
