Sell a Square D transformer from a building or plant
Texas Transformer Buyers buys single units and whole lots, whether new in a crate, used, working, retired or failed. Our yard and office are at 6402 McGrew St, Houston, TX 77087, and we coordinate trucking and pickup from sellers statewide.
Square D is a Schneider Electric brand found on general-purpose dry-type transformers in commercial buildings across Texas. Schneider Electric and Square D also supply medium-voltage dry-type and cast resin transformers, often as part of unit substations. Send what you have rather than ruling out equipment because it is older or no longer operating.
For a facility owner, contractor or project manager, the first step is documenting the equipment and its removal status. Tell us whether it is still installed, already disconnected, stored indoors or sitting with other equipment from a completed project.
Square D and Schneider Electric equipment we buy
We evaluate Square D dry-type surplus as well as used equipment removed during building renovations, plant changes and electrical upgrades. Include every transformer in the lot, even when ratings or conditions differ. We buy any brand, so mixed-brand inventory can be submitted together.
Our buying range runs from 10 kVA pole-mounts to large MVA substation and power transformers. kVA means kilovolt-amperes, and MVA means megavolt-amperes; both describe transformer capacity. For this brand, focus your photos and inventory on the following equipment.
- General-purpose dry-type transformers: Send the rating plate, enclosure photos and a description of the installation or storage condition.
- Cast coil transformers: Include medium-voltage dry-type and cast resin equipment, with photos showing the coils and enclosure where safely accessible.
- Unit substations: Show the transformer and adjoining sections. Square D switchboards and switchgear are common secondary sections; identify what is included in the proposed sale.

Find the serial number, manufacture date and ratings
Start with a clear Square D transformer nameplate photo. Look for the identification plate on the enclosure or accessible equipment surface, without opening energized compartments. Photograph the entire plate straight on, then take closer images if small text is difficult to read.
Look for fields labeled serial number and date of manufacture, or similar wording. Copy them exactly as shown rather than interpreting a code. If a date is absent or unreadable, report that and send the photo; an installation date is not necessarily the manufacturing date.
Capture capacity, primary and secondary voltage, phase, frequency and impedance wherever listed. Primary voltage is the incoming supply rating, secondary voltage is the output rating, and impedance describes the transformer's electrical opposition under specified conditions. These details help distinguish units that look similar but serve different applications.
Use our transformer nameplate reading guide to organize the information. For a unit substation, photograph the transformer plate separately from switchboard or switchgear labels so the ratings remain tied to the correct equipment.
Older and current nameplates need the same careful attention
Your equipment may carry Square D or Schneider Electric identification. Send the actual branding and wording visible on each plate rather than relabeling everything under one name. We buy both brands, and the specific ratings matter more than a general description of the logo.
For older equipment, avoid assigning a manufacturing year based on appearance alone. For current equipment or new surplus, include available paperwork alongside the plate photos. If the enclosure label and transformer identification differ, photograph both and explain where each was found.
Do not assume two units are identical because their enclosures match. Give each transformer a simple inventory label, then use that label on its photos and notes. This is especially helpful when selling several units with different capacities, voltages or operating histories.
How age and condition affect the offer
As a Square D transformer buyer, we assess age alongside ratings, condition, completeness and the available equipment history. Age alone does not describe whether a unit is useful for another installation. A readable nameplate and a clear account of its service history make the evaluation more informed.
For used Square D transformers, describe why each unit was removed and whether it operated before removal. Note visible coil damage, overheating, corrosion, missing panels or terminals, and storage exposure. If it failed, explain the known failure rather than describing it simply as used.
Share existing test reports or maintenance records if available; do not energize equipment just to create a sale demonstration. New-in-crate equipment should also be documented, including packaging condition and any visible damage. Our guide to used transformer value explains the information that helps support a valuation.
Send photos and details for an offer
To sell a Square D transformer, call or text (951) 403-5738, email Industrial832@gmail.com, or submit your transformer details. We evaluate the information and respond with an offer. Include a contact name and identify the Texas city where the equipment is located.
- Send nameplate and overall photos for each unit, plus the quantity and condition.
- List known ratings, serial numbers and manufacturing dates without guessing at unreadable fields.
- Describe included substation sections, loose parts and available documentation.
- Explain access conditions, removal status and any loading restrictions at the site.
Agree on pickup and prepare the equipment
You get the price, payment terms and pickup details in writing before a truck is loaded. The seller, or the seller's qualified electrical contractor, must de-energize and disconnect the equipment. We plan the trucking and loading with you ahead of pickup.
Provide dimensions and weight if available, along with photos of the loading area and route out of the building. Identify stairs, narrow doors, overhead restrictions or sections that remain attached. For a unit substation, clearly define which pieces are ready for removal and which are staying.
Tell us whether the transformer is on a pallet, in a crate or still anchored in place. Accurate site information helps coordinate the truck and loading arrangements without treating electrical disconnection as part of freight pickup.
Frequently asked questions
Can I sell one Square D transformer rather than a whole lot?
Yes. We buy single transformers and whole lots across Texas. Send the individual unit's nameplate, overall photos, location and condition for an evaluation.
Do you buy failed Square D or Schneider Electric transformers?
Yes. We buy working and failed equipment. Describe the failure and visible damage, and include any existing records that explain what happened.
What if I cannot find the manufacturing date?
Send clear photos of every identification plate and say the date is unknown. Do not substitute the building's age or installation date for the transformer's manufacturing date.
Can I offer a complete unit substation?
Yes. Photograph the transformer and adjoining sections, identify what is included, and provide each section's available ratings. Note any components that must remain at the site.
Do you handle electrical disconnection before pickup?
No. The unit has to be de-energized and disconnected by the seller or the seller's qualified electrician. We coordinate trucking and load-out under the agreed pickup details.
