UNSPSC 32121602: Fusistors

UNSPSC 32121602 Fusistors (Commodity) represents electrical protection and control relays that state and local governments procure for utility system modernization, facility infrastructure upgrades, and emergency backup power systems. Recent solicitations show a mix of utility authorities, counties, school districts, and transit agencies buying specialized relay equipment, electrical components, and associated control enclosures. Kissimmee Utility Authority's August 2026 sole-source quotation for SEL 451 Protection, Automation, and Bay Control System relays and SEL 751 Feeder Relays exemplifies the core work—replacement of aging protection relays with standardized, interoperable equipment that integrates with existing SCADA infrastructure and standardized protection schemes without requiring system redesign. Hillsborough County's June 2026 ITB for Schneider Electric components valued at $519,787.19 over two years reflects ongoing procurement of standardized electrical components for SCADA control panels; the county requires authorized distributors and prohibits substitutions. Northside Independent School District's September 2026 IFB for electronic equipment, parts, repairs, rentals, and services illustrates the broad consumption of electrical goods and maintenance across school infrastructure, with all vendors required to respond or forfeit future business opportunity.

Activity concentrates in Florida and Texas, with repeat buyers including Hillsborough County (control panels, Schneider components, relay equipment), utility authorities (Kissimmee Utility Authority, Bay County Utility Services), municipalities (City of Arlington, City of Tampa), and transit authorities (Trinity Metro). Gwinnett County, Georgia's June 2026 annual contract for ballasts and capacitors (approximately 200 units annually each of metal halide ballasts and capacitors for Parks and Recreation maintenance) shows regional geographic spread. Hillsborough County's August 2026 ITB for pump station control panels—extended from September 22 to September 29, 2026, with an estimated contract value of $3.66 million over two years and ten competitive bids ranging from $2.55 million to $5.1 million—demonstrates substantial procurement scale and competition in specialized panel fabrication. Trinity Metro's July 2026 IDIQ contract for electrical materials serving maintenance and emergency operations across Tarrant County, Texas facilities reflects recurring demand for commodity electrical supplies under indefinite-delivery vehicles.
