Stop if equipment shows burn, melting, or structural cracks; follow the current manufacturer instructions and safety data. Do not attempt live testing or field replacements yourself — use appropriately qualified electrical professionals and follow the authority having jurisdiction for safe handling and removal.
How we review qualifying 3VA breakers
We review qualifying Siemens SENTRON 3VA molded‑case circuit breakers, replacement trip units, and related factory accessories for potential purchase. Submitting items begins a review process; it is not an automatic purchase, appraisal, or safety inspection. Provide clear identification and condition details so we can evaluate commercial suitability and estimated value.
Our interest is commercial and conditional: we evaluate items by serial/catalog identification, physical condition, and whether the pieces are complete and correctly labeled. The more exact the identification you supply, the faster and more accurate the review will be.
- We may request additional photos or cradle‑to‑cradle paperwork during review.
- Submitting a listing is a purchase review request, not an acceptance or pickup authorization.
- We do not imply Siemens endorsement or manufacturer affiliation by reviewing items.
Exact identification fields we need
Identify each breaker by the visible catalog or type number stamped on the breaker body and the trip unit designation. For 3VA family breakers, the original Siemens SENTRON 3VA label on the frame or trip unit is the primary evidence we use to confirm series and variant. If a serial number, date code, or production lot number is present, include that too.
Photograph and list any auxiliary parts, handle kits, mounting adapters, and manufacturer spare numbers. If the breaker has been repainted, relabeled, or field‑modified, note that explicitly. Incomplete or missing factory labels significantly slow review and usually reduce value.
- Required: clear photo of the 3VA nameplate or molded label.
- Useful: catalog/type number, trip unit code, frame size, and serial/date code.
- Helpful: photos of the front, back, right and left sides, and any accessory panels.
Original labels and UL‑variant marking distinctions
Within the 3VA family, certain breakers carry different third‑party safety markings or variant letters that affect intended application and valuation. Look for any small marking blocks or stamped letters near the manufacturer label that indicate a UL or other listing/variant. Photograph these markings closely as they are treated separately in review.
When submitting, note whether the breaker shows an original, factory‑applied label and whether any listing marks are intact or altered. We distinguish items with original labels from those with aftermarket labels or missing marks; original labeling typically results in a clearer market fit and may affect pricing, while altered or missing markings require additional verification.
- Photograph any small variant letters or symbols adjacent to the Siemens label.
- Note if the breaker shows an explicit listing mark, and whether it is legible.
- If labels are removed or obscured, state that clearly and include close photos of the frame where labels once were.
Condition language we use and what we accept
We accept new‑surplus, unused factory spares, and certain used 3VA breakers that are complete and have original identifying labels. Condition descriptions should be precise: 'unused/new‑surplus in original packaging', 'used—field installed but fully intact', or 'refurbished by third party (describe work done)'. Avoid subjective terms without detail; specify mechanical wear, contact erosion, or any visible damage.
We do not perform energized testing as part of the submission step. If you report that a breaker was removed from service because of a trip or fault, include the circumstances and any maintenance records. Items showing evidence of overheating, cracked insulation, arc damage, or missing critical parts may be excluded from purchase consideration or priced accordingly.
- Acceptable: new‑surplus with original labels; used complete units with legible identification.
- Reduced value or excluded: missing labels, visible thermal damage, broken operating mechanisms.
- Document any third‑party refurbishment or part replacements in your submission.
Photos, lot organization, and submission best practices
Organize breakers into lots by catalog/type and condition. A lot that mixes multiple catalog numbers or multiple UL‑variant mark types will be harder to price. For each lot, supply a consistent photo set: an overall shot of the lot, and for each unique catalog/type, the mandatory closeups of labels and front/back sides.
Number items in your photos to match your inventory list so we can cross‑reference quickly. If you offer multiple identical pieces, show one representative unit plus at least one detail photo for any units that differ. Clear, well‑lit photos reduce back‑and‑forth and speed the review.
- Supply a spreadsheet with catalog/type, trip unit code, serial/date codes, and count per lot.
- Include representative photos and at least one detailed label photo per catalog/type.
- Group items by identical label/variant and condition to simplify the review.
How we evaluate commercial fit and value
Valuation considers identification, completeness, condition, and market demand for that exact 3VA variant. Breakers with original 3VA labels and intact listing marks that match common industrial catalog numbers are generally the easiest to place. Uncommon trip options, mismarked units, or parts missing critical components require extra due diligence and are valued accordingly.
We may adjust value for quantity (lots), rarity of the specific trip unit or accessories, and the presence of original packaging. Because the commercial value depends on those exact factors, each submission receives an individualized review and proposed purchase terms where applicable.
- Higher value drivers: intact original 3VA labels, complete accessories, new‑surplus condition.
- Lower value drivers: missing or altered labels, mechanical damage, mixed‑variant lots.
- We provide a conditional purchase proposal only after review of identification and photos.
What to submit and the next step for a review
To start a review, provide a clear inventory list and the best possible photos described above. Include the catalog/type numbers, trip unit codes, counts per lot, and any known service or refurbishment history. If you have multiple lots, submit them separately so each can be reviewed on its own merits.
Submitting materials initiates a commercial review. A review may lead to a conditional purchase proposal, a request for more information, or a decline. Submission is not an appraisal, offer, acceptance, safety inspection, purchase order, pickup commitment, or shipping authorization. We review and respond based on the evidence provided.
- Send photos and inventory as described; label lots clearly.
- Expect follow‑up questions on unidentified or altered items.
- A conditional purchase proposal requires verification of identity and condition before final acceptance.
