Projects are revised
Changed motor sizes, cancelled installations and panel design revisions can leave unused relays outside the final bill of materials.

How surplus happens
Motor control requirements change.
The spare inventory often remains.
Overload relays are held to support particular motors, starters and control systems. When machinery is replaced, panels are redesigned or purchasing standards change, the relays on the shelf may no longer match your active equipment.
Equipment is retired
Replaced machines and upgraded motor control centers can leave maintenance spares for starter families your facility no longer uses.
Purchasing overlaps
Duplicate orders, stocking changes and consolidated storerooms can create excess quantities across multiple locations.
Before releasing stock, check with maintenance and electrical personnel which relays still support active equipment, required spares or planned projects.
Identify what you have
Overload relay inventory worth discussing.
We welcome inquiries about complete relays, modular assemblies and associated motor protection stock. Exact identification, current range, condition and completeness provide the starting point for review.
Bimetallic thermal relays
Thermal overload relays held for industrial motor starters. Record the full catalog number, marked adjustment range, trip class and mounting configuration.
Electronic overload relays
Solid-state units with model-specific protection and configuration features. Include the current range, supply details where applicable, and installed options.
Eutectic & heater-type units
Thermal relay assemblies that use separate heater elements. Identify both the relay body and the heaters included, rather than describing the body alone as a complete configuration.
Modular relay assemblies
Systems comprising sensing, control and communication modules. Photograph each module code and identify whether the assembly is complete.
Starter-mounted & separate units
Relays supplied with contactors or separate mounting hardware. List each component independently and document known compatible starter families.
Heaters, modules & accessories
Spare heater elements, current sensors, mounting kits and other identifiable accessories. Include exact part numbers, quantities and the associated relay series when known.
These descriptions can overlap. An electronic relay may also be modular or starter-mounted. Identify the actual assembly and included components.
Recognizable equipment. Specific configurations.
Start with the brand.
Keep the complete catalog code.
Common manufacturers and product families in industrial motor protection include the names below. Other brands and legacy inventory are welcome in an inquiry.
Allen-Bradley · Schneider Electric / Square D · Siemens · ABB · Eaton · Mitsubishi Electric · Fuji Electric · Lovato Electric
Brand names identify equipment only. Industrial Overload Relays does not claim manufacturer authorization, endorsement or affiliation.
Current range is only part of the identity.
Relays with similar ampere ranges may differ in trip class, mounting arrangement, reset options, sensing configuration and available functions. A complete model code helps distinguish these differences.
- Copy all prefixes, suffixes and series markings.
- Record the adjustment range exactly as labeled.
- Photograph the relay and original box labels.
- Identify modules and accessories separately.
- State clearly when specifications are unknown.
Condition and traceability matter
Separate unused spares from removed equipment.
Sealed stock, opened unused units and relays removed from service should be described separately. Share purchasing records, test reports and known service history where available.
Disclose damaged terminals, missing covers, corrosion, heat discoloration, modifications and any known faults. A clean exterior does not establish functional performance.
Keep relay modules, mounting parts and documentation together. For electronic units, include available configuration or firmware information when it can be reliably identified.
Understand the equipment category
Overload protection is part of a coordinated motor circuit.
An overload relay addresses motor overload conditions as part of the control arrangement. It should not be assumed to provide the circuit’s short-circuit protection or to replace the contactor or other protective devices.
Document the relay as it is supplied. Suitability for another starter or application needs to be checked against manufacturer specifications and the complete circuit requirements.
Preserve the details that make the lot understandable.
Avoid combining similar-looking relays or loose heater elements into unidentified bins. Keep different model codes and ranges separate, and count pieces rather than assuming every carton is full.
For assembled starters, explain whether the offer includes the contactor, overload relay, enclosure and accessories. Clear scope helps distinguish a complete assembly from spare components.
From excess stock to a clear inquiry
Start with the inventory you have.
An existing stock list, a partial export or readable photos can establish the starting point. Be clear about what has been counted and what remains unidentified.
Confirm genuine surplus
Check active starter platforms and maintenance needs. Select excess quantities and items no longer required for current or planned equipment.
Group and identify
Sort by exact catalog number, count quantities and record condition. Photograph labels and keep modules, heaters and accessories associated with the correct units.
Discuss selling the stock
Share the details, location and timeline. Inventory fit, commercial terms and packing or transport requirements are confirmed for the specific lot.
A realistic view of resale potential
Original cost is a reference.
Today’s inventory is the starting point.
Potential resale value depends on model, range, condition, completeness, quantities and demand. A familiar brand or discontinued status does not guarantee a buyer or a particular offer.
Make the next decision easier.
A clear surplus review helps maintenance and purchasing distinguish required stock from duplicates and obsolete requirements. Retain identification and update inventory records when stock changes hands.
You can begin with a partial list. Prioritize exact identification and an honest condition description over guessed specifications.
Common questions
Selling surplus industrial overload relays
Can I inquire about used overload relays?
Yes. Describe their service history, why they were removed and any known faults. Include photos and available test records. Used or untested condition needs to be considered during review.
What if I have a mixed lot of brands and current ranges?
Group by exact catalog number where practical and provide quantities and overview photos. Identify stock that remains uncounted or unidentified rather than combining it with confirmed items.
Should I include separate heater elements?
Yes. List the heater part numbers and quantities separately, and identify the relay body or starter family when known. Do not assume heater compatibility based on appearance alone.
Can I submit incomplete electronic relay assemblies?
Include them with each module identified and missing components disclosed. Photograph the sensing, control and communication modules present. Acceptance depends on the specific inventory and condition.
Are older or discontinued relays worth submitting?
Include them with their original labels and available documentation. The exact model, range, condition and demand need to be considered; age alone does not establish resale value.
Is there a minimum quantity or guaranteed purchase?
Share the stock you have. Whether a transaction makes sense depends on the items, quantities, condition and logistics. Any offer or commercial arrangement is confirmed after review.
Put excess motor protection stock on the agenda
Have overload relays your company no longer needs?
Unused project stock, duplicate maintenance spares or a larger storeroom lot — start with the details you have.
