UNSPSC 39122333: Solid state relay

UNSPSC 39122333 Solid state relay, a Commodity code, covers electrical relay components and switching devices that state and local governments procure as part of broader electrical equipment, parts, and supplies contracts. Recent solicitations show state and local buyers purchasing solid state relays alongside contactors, starters, switches, and control components as catalog-line items within blanket supply agreements rather than as standalone specialty procurements. The code appears intermittently tagged in electrical equipment RFPs, though few solicitations isolate solid state relays as a distinct line item; instead, they embed relay procurement within larger electrical parts frameworks or control system integration projects. Issuing bodies include independent school districts (Northside Independent School District in San Antonio), municipal water and reclamation authorities (West Basin Municipal Water District, Orange County Florida, Eastern Municipal Water District, Hillsborough County), cities and transit authorities (City of Phoenix, City of Charlotte), and county facilities management offices. The geographic spread spans Texas, California, Florida, Oregon, and a multi-state cooperative purchasing vehicle through Sourcewell anchored in Minnesota, with recent activity concentrated in water utility and municipal infrastructure upgrades.

Representative recent opportunities underscore the code's actual procurement pattern. Northside Independent School District (San Antonio, Texas) issued IFB 2026098 on June 8, 2026, for electrical equipment, parts, supplies, rentals, repairs, and services with responses due July 1, 2026—a broad catalog contract in which relays function as commodity line items. Eastern Municipal Water District (Riverside County, California) posted RFP AR3928 on April 11, 2026, for a medium voltage soft starter installation at Auld Road Booster Station, with a May 9, 2026 deadline; this project-specific procurement requires soft starter units rated at 2400V, 97A, and 450HP from authorized distributors, representing control component integration rather than relay-specific sourcing. Orange County, Florida issued IFB Y26-604 on April 21, 2026 (due April 30, 2026) for Eastern Water Reclamation Facility electrical and mechanical upgrades, including replacement of 15 kV switchgear with new protective relays alongside generator and control system work. The City of Phoenix's three-year electrical parts and supplies contract (IFB 26-FMD-012, posted March 24, 2026) and the City of Tucson's annual requirements for fabrication of station control panels (RFP 240048, posted March 17, 2026, for approximately $980,000 per year) illustrate how relays and control components anchor utility-scale infrastructure maintenance and upgrade programs. Solid state relay procurement activity remains embedded in these larger frameworks with no recent standalone relay tenders identified in state and local postings.
