UNSPSC 39121629: Fuse block

UNSPSC 39121629 Fuse block, a Commodity code, covers discrete electrical fuses and assembled fuse kits that state and local governments procure for infrastructure maintenance, transit operations, and facility management. Recent solicitations show active procurement of current-limiting fuses in multiple amperage ratings, packaged fuse assemblies with mounting hardware, and component fuses for underground residential distribution (URD) applications, alongside broader electrical supplies categories that include fuses as line items. The issuing bodies span school districts, transit authorities, municipal utilities, and city public works departments. Northside Independent School District (San Antonio) issued an IFB for electrical equipment, parts, and supplies with a July 1, 2026 response deadline; the City of Austin Purchasing Office solicited fuse kits twice in April 2026 (Invitations for Quotation due May 5, 2026) specifying 150-amp and 200-amp current-limiting fuse kits assembled with URD tap hardware; the Dallas Area Rapid Transit Authority (DART) posted separate ITBs for specific fuse ratings (40-amp, 1000-volt units in April 2026 and 3-amp ATC fuses in February 2026); Pinellas County School District in Florida solicited electrical supplies including fuses with a March 27, 2026 deadline; and the City of Phoenix Public Works Department issued an IFB for electrical parts and supplies encompassing fuses as components of a broader catalog-based contract.

Geographic concentration centers on Texas (Austin, Dallas DART, Pinellas County School District in Florida), with activity in Arizona (Phoenix). The issuing bodies include municipal utilities and transit authorities that maintain substantial electrical infrastructure, school districts managing districtwide maintenance operations, and city public works departments. Most solicitations employ competitive bid formats (IFB, ITB, IFQ) with response windows of one to three weeks and require FOB Destination pricing with freight included. Established manufacturers such as Cooper Bussman, Ferraz Shawmut-Gould, and Reliance Electric appear across specifications, with several solicitations requiring vendor-assembled kits meeting precise dimensional and material standards rather than off-the-shelf components.
