UNSPSC 39122315: Electromagnetic relay

A relay equipped with electromagnet, armature and contact point, and opens and shuts the contact point by attracting armature by generating magnetic flux by the current flowing in the wound wire of electromagnet.

UNSPSC 39122315 Electromagnetic relay (Commodity) covers the supply and installation of electrical relay components and associated electromagnetic switching equipment used across state and local infrastructure—water treatment plants, airports, schools, transit systems, and municipal facilities. Recent solicitations show state and local procurement offices buying relays as components within broader electrical system upgrades and maintenance contracts, particularly for motor control centers, booster station controls, SCADA system replacements, and access control infrastructure. The code captures both commodity supply (relays ordered as discrete parts or in kits) and their integration into larger control panel fabrication and electrical installation projects where relay functionality is essential to system operation.

Issuing bodies include county water districts, municipal water utilities, school districts, transit authorities, and county commissioners' offices. Hillsborough County Water Resources Department and Eastern Municipal Water District (Riverside County, California) have posted multiple recent opportunities across relay-adjacent electrical components and control systems. Geographic activity spans California, Florida, Georgia, Oregon, Minnesota, Arizona, and Texas, with particular concentration in water utility procurement in Florida and California. Representative recent opportunities include Hillsborough County's ITB-26-00123 for Square D Brand Contact Kits (due February 24, 2026), Eastern Municipal Water District's RFP for medium voltage soft starter installation at Auld Road Booster Station (due May 9, 2026), Orange County Florida's IFB Y26-604 for Eastern Water Reclamation Facility electrical and mechanical upgrades including 15KV switchgear modifications (due April 30, 2026), and the City of Phoenix's three-year electrical parts and supplies framework (due July 9, 2025) sourcing components from manufacturers including Allen Bradley, Eaton, GE, Schneider Electric, and Siemens. Activity signals ongoing infrastructure modernization in municipal water systems and utility control upgrades, with relay replacement typically driven by aging equipment replacement cycles and system reliability demands rather than new facility construction.
