UNSPSC 39122318: Frequency relay

A relay that becomes operational when the frequency reaches prescribed value.

UNSPSC 39122318 Frequency relay is a Commodity code representing electrical components and control devices that state and local governments purchase for infrastructure maintenance, system upgrades, and facility operations. Recent solicitations show these relays appearing as discrete line items within broader electrical procurement and construction projects—particularly in water treatment facilities, power distribution systems, and equipment control applications where frequency sensing and protective switching functions are required. State and local buyers rarely solicit frequency relays as standalone procurements; instead, they emerge as component-level specifications within larger electrical system overhauls, motor control upgrades, and facility electrification projects managed by water districts, municipal utilities, school districts, and county departments.

The issuing bodies pursuing work under this code span water utilities (Eastern Municipal Water District in California, City of Tucson Water Department, Orange County Florida water reclamation operations, Hillsborough County Water Resources), municipal and county infrastructure departments (West Basin Municipal Water District, City of Phoenix Public Works, Monroe County Facilities Management), school districts (Northside Independent School District in San Antonio, Bibb County Public Schools), and regional transit authorities (Charlotte Area Transit System). Recent activity concentrates in California, Florida, Texas, Oregon, and the Southeast, with representative opportunities including the Eastern Municipal Water District's medium voltage soft starter installation at Auld Road Booster Station (RFP RFPAR3928, May 9, 2026 response date), Orange County Florida's Eastern Water Reclamation Facility electrical upgrades including switchgear and protective relay replacement (IFB Y26-604, April 30, 2026 response date), and West Basin Municipal Water District's motor control center replacement in Torrance, California (RFB RFBTH0120, March 31, 2026 response date). These water utility and facility infrastructure projects typically bundle frequency relays and related protective devices as specified components within system-wide electrical modernization contracts rather than as independent commodity purchases.
