UNSPSC 39121603: Miniature circuit breakers

UNSPSC 39121603 Miniature circuit breakers, a Commodity code, names small electrical switching devices that state and local governments procure as components within broader electrical infrastructure, maintenance, and equipment upgrade projects. Recent state and local solicitations show this code applied across water utilities, school districts, municipal facilities, and transit authorities acquiring miniature circuit breakers as part of equipment replacements, control panel fabrications, electrical system upgrades, and routine maintenance supply contracts. The actual procurement activity spans embedded component sales within larger system integrations—such as control panels, motor control centers, and SCADA replacements—as well as standalone electrical parts and supplies contracts that bundle miniature circuit breakers with other switching and distribution equipment. Issuing bodies include water districts and municipalities managing utility infrastructure, independent school districts procuring electrical maintenance supplies, county governments operating public facilities, and transit authorities maintaining operational systems.

Recent activity concentrates in California, Florida, Texas, Oregon, and Georgia. The Eastern Municipal Water District (EMWD) in Riverside County sought a medium voltage soft starter installation with associated control system integration (May 2026 RFP); the City of Tucson released an annual requirements contract for station control panel fabrication specifying Allen-Bradley components and UL508A-rated panel assembly, with approximately $980,000 annual spend (March 2026 RFP with January 2024 posting date); Northside Independent School District in San Antonio solicited electrical equipment, parts, supplies, and services on an as-needed basis with sealed bids due July 1, 2026 (IFB 2026098, June 2026); Orange County, Florida issued an invitation for bids on electrical and mechanical upgrades at the Eastern Water Reclamation Facility involving switchgear, generator system replacements, and control system work (IFB Y26-604, April 2026); and the City of Phoenix Public Works Department established a three-year electrical parts and supplies contract requiring single-percentage discounts off manufacturer lists from major suppliers including Schneider Electric and Eaton (IFB 26-FMD-012, March 2026). The code shows steady activity across utility and municipal procurement, though recent opportunities reflect miniature circuit breakers primarily as embedded components within larger electrical systems and maintenance supply frameworks rather than standalone commodity buys.
