UNSPSC 39122319: Direct current relay

It is used for the purpose of cutting off circuit or protecting line by detecting abnormal state during operation of network system with capacity of less than DC 300V with high sensitivity.

UNSPSC 39122319 Direct current relay is a Commodity code. State and local governments procure direct current relays as component parts embedded in larger electrical and control system installations, particularly in water treatment facilities, lift stations, and utility infrastructure upgrades. The recent solicitations that reference this code or its functional equivalent show procurement of complete electrical and control system assemblies—including motor control centers, soft starters, generator switchgear modifications, protective relays, and station control panels—rather than standalone DC relays as discrete line items. School districts, municipal water utilities, county water departments, and transit authorities are the primary issuing bodies. Northside Independent School District (San Antonio, Texas) solicited electrical equipment, parts, supplies, and services via IFB due July 1, 2026. Eastern Municipal Water District (Riverside County, California) solicited medium voltage soft starter installation and startup services via RFP due May 9, 2026, specifying Schweitzer microprocessor-based protective relays as part of the work scope. Orange County, Florida solicited electrical and mechanical upgrades at a water reclamation facility via IFB due April 30, 2026, including replacement of protective relays with Schweitzer units. West Basin Municipal Water District (California) solicited motor control center replacement via RFB due April 23, 2026.

Recent activity concentrates in Texas, California, and Florida, with secondary activity in Oregon and Georgia. The code shows limited standalone procurement; most opportunities bundle DC relay components into larger electrical modernization, control system replacement, or infrastructure upgrade contracts. Geographic spread reflects aging utility infrastructure and water system upgrades, with the heaviest concentration in California and Florida. The Sourcewell cooperative procurement for law enforcement equipment (RFP #061626, due June 16, 2026) represents a broader purchasing framework but does not specify relay procurement. The City of Phoenix electrical parts and supplies contract (IFB 26-FMD-012, three-year term starting October 2025) and the City of Tucson control panel fabrication requirements contract (RFP 240048, estimated annual spend $980,000) indicate that DC relays and similar electrical components move through both standing supply agreements and project-specific system integration contracts.
