UNSPSC 39122335: Relay socket or base

UNSPSC 39122335 Relay socket or base (Commodity) describes electrical components that state and local procurement offices source primarily through facilities maintenance and infrastructure upgrade contracts. Recent solicitations under this code span water utility equipment installations, electrical system replacements at municipal facilities, and general electrical parts supply frameworks. State and local issuers pursuing relay sockets and bases include county water districts, municipal water departments, school districts, county commissioners' offices, and city public works departments. The actual buying pattern reflects two concurrent streams: specialized component procurement tied to specific capital projects (such as motor control center replacements, SCADA system upgrades, and booster station installations) and blanket-purchase agreements for general electrical supplies and parts. School districts and water utilities represent the most active buyer categories in recent postings.

The Eastern Municipal Water District (EMWD) in Riverside County, California, issued RFP RFPAR3928 in April 2026 for medium voltage soft starter installation and commissioning at the Auld Road Booster Station, with proposals due May 9, 2026.

West Basin Municipal Water District in Torrance, California solicited RFB RFBTH0120 in April 2026 for a motor control center replacement project incorporating design, installation, testing, and commissioning. Northside Independent School District in San Antonio, Texas issued IFB2026098 in June 2026 for electrical equipment, parts, supplies, rentals, repairs, and services, with sealed bids due July 1, 2026. The City of Phoenix established a three-year electrical parts and supplies agreement (IFB 26-FMD-012) with local stocking distributor requirements and 48-hour delivery standards. Geographic activity concentrates in California (water utilities in Riverside and Los Angeles counties), Florida (Orange County and Hillsborough County water and facilities departments), Texas (school district infrastructure), Arizona (municipal water systems), and the Pacific Northwest, with scattered activity across other states through cooperative purchasing vehicles. The code sees steady municipal and utility-sector demand, particularly for water system control modernization and school district infrastructure maintenance.
