UNSPSC 39122307: Auxiliary relay

A relay used as an auxiliary for protective relay with purposes including increase in contact capacity, increase in contact points, addition to time delay or others.

UNSPSC 39122307 Auxiliary relay, a Commodity code, names a single electrical component; however, recent state and local solicitations tagged with this code span a broader range of electrical equipment, parts, and controls procurement rather than relays alone. The code appears in opportunities ranging from general electrical parts supply contracts to specialized motor control center replacements, soft starter installations, and water facility electrical upgrades. Buying bodies include school districts, municipal water utilities, county governments, and transit authorities. The issuing-body mix reflects operational infrastructure demand: Northside Independent School District (San Antonio, Texas) seeks general electrical equipment, parts, and supplies through an IFB; Eastern Municipal Water District (Riverside County, California) solicits medium voltage soft starter installation and training through an RFP; Orange County, Florida purchases electrical and mechanical upgrades at a water reclamation facility through an IFB; and the City of Phoenix establishes a three-year as-needed electrical parts contract through an IFB. Water utilities and school districts emerge as repeat buyers under or near this code.

Recent activity concentrates in California, Florida, and Texas. Representative opportunities include Northside Independent School District IFB2026098 for electrical equipment, parts, supplies, rentals, repairs and services, due July 1, 2026, which replaces an expiring contract and requires all vendors to rebid or forfeit future business; Eastern Municipal Water District RFPAR3928 for medium voltage soft starter purchase, installation, and training at the Auld Road Booster Station, due May 9, 2026, with a mandatory job walk on April 21, 2026; Orange County, Florida IFB Y26-604 for Eastern Water Reclamation Facility electrical and mechanical upgrades including switchgear, generator, and control system work, due April 30, 2026, with a non-mandatory pre-bid conference on April 2, 2026; and City of Phoenix IFB 26-FMD-012 for electrical parts and supplies on a three-year term beginning October 1, 2025, with a pre-offer conference on June 4, 2025. None of these opportunities disclose incumbent vendors or specific award values in the source material.
