UNSPSC 39121601: Circuit breakers

UNSPSC 39121601 Circuit breakers (Commodity) covers the procurement of discrete circuit breaker units—standalone protective switching devices rated for low to medium voltage distribution—that state and local governments purchase for utility infrastructure, facility electrical systems, and industrial applications. Recent solicitations show state and local buyers acquiring replacement circuit breakers for substations, outdoor distribution networks, and facility service panels, as well as fabricated electrical control panels and switchgear assemblies that incorporate circuit breakers as integrated components. The issuing bodies span municipal utilities (Kissimmee Utility Authority, City of Ocala, Lubbock Power & Light), county governments (Hillsborough County, Fairfax County), state agencies (Texas Department of Criminal Justice, Illinois Department of Corrections), universities (University of Mississippi), wastewater treatment districts (Broward County, City of Lavonia), and school districts (Pinellas County Schools). Florida utilities and counties account for significant recent activity, alongside Texas municipalities and state correctional agencies.

Representative opportunities include Kissimmee Utility Authority's IFB for replacement of three 15 kV vacuum circuit breakers at Marydia Substation (sealed bids due November 15, 2016; two vendors bid; $74,710 low), Lubbock Power & Light's RFP for three 15 kV outdoor vacuum circuit breakers with 2000 ampere rating and protective relays for Erskine Substation (proposals due September 24, 2026), and Hillsborough County's ITB for pump station control panels and enclosures in multiple voltage configurations including UL 508A-certified fabrication (estimated $3.66 million over two years; bids due September 29, 2026). Fairfax County issued a five-year term contract IFB for switchgear testing and preventative maintenance on low and medium voltage circuit breakers and motor control centers across wastewater facilities (bids due June 9, 2026). Broward County posted multiple open-end procurements for fabrication and refurbishment of water and wastewater control panels incorporating circuit breaker assemblies (bids due June 22 and June 26, 2026). Activity clusters in Florida, Texas, Georgia, Virginia, Mississippi, and Illinois, with work ranging from single-unit replacements to ongoing panel fabrication and maintenance contracts.
