Stop and contact appropriately qualified electrical professionals if you observe arcing, burning, unknown fluids, or unsecured lifting conditions. Follow current manufacturer instructions and applicable authority having jurisdiction. Submitting photos or inventory is not a safety inspection, purchase order, or removal authorization.
We review qualifying medium‑voltage vacuum breakers for purchase
This page explains how to prepare and submit medium‑voltage vacuum circuit breakers (VCBs) for our purchase review. We will consider units that fall inside our stated voltage range and that pass a review for electrical condition, transportability, and environmental considerations. Submitting materials starts a review; it is not an appraisal, offer, acceptance, safety inspection, or purchase authorization.
Any handling requires written confirmation from us; until then, no movement is authorized. Submissions are evaluated on the materials provided and may require additional information before we can discuss next steps.
- We review qualifying items for purchase — not every submission will be purchased.
- Submissions without the requested photos or nameplate details can delay evaluation.
- Written confirmation is required before any transport or handling is authorized.
What we consider: voltage, breaker types, and limits
Our current stated voltage range for medium‑voltage vacuum circuit breakers is 1 kV to 36 kV. That range reflects typical MV distribution and industrial applications; items outside this range are typically outside our purchase review scope.
We consider standard indoor and outdoor VCB designs, including fixed and withdrawable assemblies, provided the nameplate shows a rated voltage and interrupting capability within our scope and the unit can be prepared and transported safely by qualified parties. We do not determine installation suitability from photos; suitability for service requires manufacturer documentation and qualified engineering review.
- Stated review range: 1 kV – 36 kV.
- We consider fixed and withdrawable vacuum circuit breakers in indoor or outdoor enclosures.
- Units with nonstandard modifications or undocumented retrofits may require additional technical review.
Exact identification fields and photos we need
Provide clear, legible photos of the original manufacturer nameplate(s) as the single most important identification element. Nameplate data should be readable in the images. Include pictures that show the nameplate location so we can confirm it belongs to the submitted unit.
In addition to nameplate photos, submit images that document serial numbers, model or type designations, rated voltage, rated current, rated short‑circuit interrupting value (kA), year or date code, mechanism type, and any accessory modules. If the breaker is mounted in a cell or cubicle, include a photo of the entire assembly and of the cubicle nameplate.
- Close‑up, well‑lit photo of the original nameplate (single image per nameplate).
- Wide shot showing the full unit and surroundings (to assess access and transport).
- Photos of serial number, model/type, rated voltage/current, and interrupting rating.
- Images of control compartments, interlocks, and any visible damage or modification.
Honest condition descriptions and safety limits
Describe condition plainly: new, like‑new, good used, parts only, mechanically incomplete, or cosmetically damaged. Flag any visible issues such as rusted linkages, missing accessories, evidence of arcing or overheating, oil or other fluids, or broken insulators. If the unit has been de-energized and mechanically secured or prepared by qualified personnel, clearly state what was performed and provide photos showing the result. Do not attempt energized troubleshooting.
Items with internal damage, evidence of previous fault currents, or unidentified fluids may require additional review and could be declined. Potential environmental or hazardous‑material concerns should be identified, and only qualified personnel should handle those conditions.
- Use clear condition terms (new, good used, parts only, inoperable).
- Disclose any known repairs, modifications, or history of fault operation.
- Stop and contact a qualified electrical professional if you observe arcing, burning, or unknown fluids.
Logistics, lifting, and lot organization
Include clear photos showing the breaker in place and any visible lift points. If the unit is already on a transport vehicle or skid, include that photo; do not relocate equipment solely for photos without written confirmation. Provide unit weights, approximate dimensions, and note whether the breaker remains in a cubicle or has been separated for transport. This information helps reviewers estimate safe handling options. Only qualified personnel should plan and perform rigging or lifting.
When submitting multiple breakers, organize submissions into lots with consistent labeling and one cover photo per lot. Provide a simple inventory list that ties each serial number to its photos. Proper lot organization shortens evaluation time and helps identify commercial groupings of compatible units.
- Photo of unit on truck, skid, or inside facility with visible orientation.
- Approximate weight and footprint dimensions for each unit (if known).
- Lot inventory sheet linking photos to serial numbers for multi‑unit submissions.
What affects buyer interest and valuation
Commercial interest depends on condition, documentation, compatibility with common installations, and quantity. Complete assemblies with intact mechanisms and original accessories typically have higher market interest than single incomplete components. Larger lots of identical models and spare parts packages can increase the chance of a commercial fit because buyers may refurbish or reuse components more efficiently.
Documentation such as manuals, schematic diagrams, recent service records, and test reports improves evaluation confidence but is not required for an initial review. Units with manufacturer nameplates, consistent serial data, and no evidence of catastrophic failure are more likely to advance to a detailed discussion after review.
- Higher interest: complete mechanisms, original accessories, multiple identical units.
- Lower interest: undocumented modifications, missing key components, or visible catastrophic damage.
- Documentation helps: manuals, wiring diagrams, and test records (if available).
How to submit and what to expect next
To start a review, send high‑resolution photos (nameplate and transport views), a simple inventory with serials and model numbers, and a brief condition note. Submissions may undergo technical, logistics, and compliance review. Until written confirmation is provided, pickup, removal, or purchase terms will not be issued.
A submission is not an offer or purchase authorization. After initial review, we may request additional photos, documentation, or an on‑site inspection conducted by qualified personnel. If a potential purchase is identified, we will describe next steps; any removal, handling, or energized work should be performed by qualified contractors under applicable requirements.
- Send high‑resolution nameplate photos and a truck/skid photo for each unit.
- Include serial numbers, model/type, rated voltage/current, and an honest condition note.
- Expect technical and logistics review before any acceptance.
