And more equipment at launch.
These tiles show a representative cross-section of what Refound carries. The full searchable catalog will list every spec variant, manufacturer, and form factor at launch.
Refound · Categories
Switchgear, breakers, and substation disconnects.
Medium-voltage and high-voltage switchgear, vacuum and SF₆ circuit breakers, disconnect switches, surge arresters, and protective relays. From 5 kV through 230 kV. Verified condition and test data on every premium listing.
Where the OEM transformer market shows 128-week lead times, the switchgear secondary market is even tighter. Refound moves units in 30 days.

Why secondary market
Why buy used switchgear
Switchgear is the part of a substation buyers most often forget to plan for. Until OEM lead times push the project past financial close. The secondary market is fragmented (broker phone trees, generic surplus catalogs without spec data). Refound is the only North American platform that gives you spec-faceted search, verified test data, and inline freight quotes in one workflow.
Inventory comes from the same professional supply channels as our transformer listings: IPP fleet rotation, decommissioned project surplus, and canceled-project inventory. Notable: many switchgear assemblies cycled out of utility ownership are well within useful life. Utilities upgrade for capacity reasons, not condition.
There's a circular-grid argument too: switchgear is one of the harder categories to recycle cleanly. Mixed metals, SF₆ reclamation, embedded controls. When units get scrapped, most of that value is lost. Pulling tested assemblies back into service preserves the original manufacturing investment and keeps complex equipment out of the waste stream. For developers, utilities, and IPPs planning the next century of grid build-out, reuse-first procurement is part of the math now.

FAQs
Switchgear FAQs
Is SF₆ gear allowed on Refound? Isn't there a phase-out happening? +
SF₆ gear is allowed; the phase-out (driven by EPA SF₆ Emission Reduction Partnership and IEC 62271-4 reporting requirements) primarily affects new manufacturing rather than secondary trading. Refound requires SF₆ leak rate verification ≤ 0.5%/year for the Verified badge. Buyers should evaluate long-term operating cost given F-gas regulations in their jurisdiction.
How can I be sure a used breaker hasn't been over-operated? +
3rd Party Verified inspections require operations-counter documentation. Sellers must disclose total operations since last refurbishment. Counters > 50% of nameplate operation life are flagged on the listing.
What about protective relay firmware? +
Microprocessor relay listings include current firmware version + manufacturer support status. Relays running unsupported firmware are flagged.
Can I buy a complete substation package on Refound? +
Yes. Several active listings are full substation re-deployments (transformer + switchgear + relays + control building). Filter by "package deal" in search.
Find the breaker the OEM doesn't have.
Refound carries verified switchgear from utility and IPP cycle-out inventory. Search live listings or save your spec criteria and we'll alert you when a match arrives.
