Switchgear & Protective Relays

Edmundson Industrial sources switchgear parts, protective relays, and metering across low- and medium-voltage equipment — drawout breakers, cells, relays, and instruments, current and long-obsolete. Send the equipment nameplate or the part number and we quote availability, condition, and lead time.

Independent sourcing, not an authorized distributor. We supply switchgear parts and relays new, surplus, and used-tested, with condition disclosed before sale. Manufacturer names are used here for reference only.

How to specify switchgear parts

Low-voltage or medium-voltage (and voltage class)
Breaker type and rating (drawout / fixed, amps, AIC)
Cell, cradle, or section details
Protective relay type (electromechanical or microprocessor)
Metering, CT / PT ratios, and instruments

How we quote switchgear and relays

Send the equipment nameplate or the part number.
We confirm low- or medium-voltage, the rating, and the relay or metering details.
We quote condition, price, and lead time — new, surplus, or used-tested, same-day on most requests.
Need a custom enclosure, panel, or mounting? Our fabrication side builds and modifies enclosures and panels to fit.

Condition & sourcing

We supply switchgear and relays new, surplus, and used-tested, with condition disclosed before sale and photos on request. We are an independent surplus and sourcing company, not an authorized distributor.

FAQ

Do you supply protective relays?

Yes, electromechanical and solid-state protective relays, current and obsolete. Send the relay model or the application and we tell you what we can find.

Can you find obsolete switchgear parts?

That is the specialty. Send the nameplate and we source or cross-reference it. Condition is disclosed before sale.

Do you handle medium-voltage switchgear?

Yes. We source MV breakers, cells, and parts from 5 to 38 kV. Send the equipment and nameplate details and we tell you what we can find.

Are you an authorized distributor?

No. Edmundson Industrial is an independent surplus and sourcing company, not an authorized distributor. We supply switchgear and relays new, surplus, and used-tested with condition disclosed before sale.
