If breakers show severe damage, arcing, oil leakage, or unknown internal modifications, stop handling and consult a qualified electrical professional and the equipment manufacturer instructions. Do not perform energized testing or field alterations; submissions are for purchase review only and are not safety inspections or purchase commitments.
We review qualifying Magnum DS and SB breakers for purchase
CircuitBreakerBuyer reviews qualifying Eaton and Westinghouse Magnum DS and SB circuit breakers and associated Magnum-series equipment for purchase consideration. This page explains what information helps our evaluation so you can prepare a submission that reduces follow-up and speeds an initial screening.
Submitting items does not guarantee a purchase. We consider original factory evidence, condition, completeness, and commercial fit for our inventory. If you want an initial conversation, include clear identification fields and recent photos as described below so we can assess whether to request more information or further evaluation. Timing and interest depend on current needs and the specifics of each item or lot.
- We do not represent Eaton or Westinghouse and accept items under a conditional review process.
- Submissions are reviewed for technical and commercial fit; results are communicated after evaluation.
- This page focuses on original Magnum DS and SB equipment and the evidence that helps our review.
How to identify Magnum DS and SB equipment
Correct identification is the single most useful thing you can provide. Magnum DS and SB breakers typically have factory labels and part numbers on the breaker body or draw-out assembly. Share the exact label text as printed, including punctuation and spacing, rather than paraphrasing model names.
Provide the identification fields below so we can match parts against our approved scope and inventory needs. If a label is missing or unreadable, describe visible castings, frame numbers, accessory types, and any stamped codes. Clear photos of these areas often resolve ambiguities that text alone does not.
- Manufacturer name or logo as printed on the label
- Complete part number or catalog number from the label
- Frame size and ampere rating (e.g., 250 A, 400 A) as shown
- Interrupting rating or kAIC if present on the label
- Trip type (thermal-magnetic, electronic trip unit) and any trip unit part number
- Date codes, serial numbers, and factory inspection stamps
Condition, completeness and original-equipment evidence
We assess condition using consistent categories: untested-as-removed, power-tested (documented), visually refurbished, and new-surplus. Describe how the breaker was removed, whether it was energized at removal, any visible damage, and whether you have recent test reports. Being specific about what you know—and what you do not—helps prevent delays.
Original-equipment evidence speeds decisions. Supply clear photos of factory labels, serial numbers, and date codes, and note whether the breaker retains original accessories such as draw-out handles, racking assemblies, shunt trips, undervoltage releases, and nameplate rivets. For pieces without labels, provide the closest readable markings and any supporting paperwork. If there are modifications or missing parts, include that information so the review can account for it.
- State if the device is untested-as-removed or comes with test reports and date
- List missing or replaced accessories and whether modifications are documented
- Note corrosion, arc damage, pitting, or thermal discoloration clearly
- Indicate whether the breaker has been cleaned, reconditioned or repainted
Photos and lot organization that make review faster
Good photos replace many follow-up questions. Attach clear, focused images of the breaker’s front, side, back, label close-ups, trip unit, and accessories. For draw-out units include images of the racking mechanism and mounting rails. Use even lighting and ensure labels are readable in the image rather than relying on transcribed text.
When offering multiple units, number each breaker and provide a spreadsheet that maps photo filenames to part numbers, serials, and condition notes. Separate functional groups and document quantities. Group identical part numbers and conditions together. For mixed lots, include a short summary in your submission showing counts per part number, counts per condition category, and any test-data links so we can quickly evaluate commercial fit.
- Photos: full device view, label close-up, trip unit, wear areas, accessories
- Number each item and keep a submission spreadsheet with key fields
- Group identical items and list quantities and condition per group
- If available, include a short video of the racking mechanism only on uninstalled, de-energized equipment captured by a qualified person; do not operate equipment in place for video
Common Magnum markings and what they tell us
Magnum-series breakers often include a combination of cast or stamped frame identifiers, machine-printed part numbers, and factory-applied date codes. Typical useful markings include the catalog or part number, trip unit model, serial number, and interrupting rating. Provide exact strings as they appear on the label; partial or altered numbers can delay review.
If you have maker-stamped or cross-reference plates showing both Westinghouse and Eaton markings, include those images. Such markers can help verify original equipment lineage, but markings alone do not establish compatibility or condition. Multiple fields are considered together when evaluating commercial fit.
- Part/catalog number printed on nameplate
- Trip unit model and part number
- Interrupting rating (kAIC) and voltage class
- Serial number and factory date or code
- Additional inspection stamps or service tags
Typical scope we evaluate (what to include in submissions)
We review Magnum DS and SB fixed and draw-out breakers, trip units, and related Magnum-series components for possible purchase consideration. Include full identification and condition details for main breakers, replacement trip units, handles, racking gear, and any available documentation. Do not ship equipment before you have explicit written instructions.
Large lots or equipment tied to decommissioning projects should be described in context: quantities by part number, storage conditions, remaining service life if known, and any environmental exposure. These commercial details help determine whether to request more information or discuss potential next steps.
- Main breaker assemblies (fixed and draw-out Magnum DS and SB units)
- Factory trip units and replacement electronic trip assemblies
- Accessory items: handles, racking mechanisms, shunt trips and UVRs
- Test reports and service records when available
How to submit items for review
Start with a single clear submission email or upload containing: a short inventory spreadsheet, high-resolution photos, and any test or service documentation. Include contact information and the precise location of the equipment. Materials are reviewed and we will contact you to request any missing details or to discuss next steps if the items meet our review criteria.
Remember that a website submission is not an appraisal, purchase order, inspection, or authorization to ship. If we request an inspection or provide conditional purchase terms, instructions will be provided in writing before any shipment or equipment removal. Keep items available for review until you receive written direction on disposition.
- Provide spreadsheet with part numbers, serials, quantities, and condition
- Attach 4–8 clear photos per unique part number plus label close-ups
- Do not ship without written instructions
- Expect follow-up with clarification requests as needed
