UNSPSC 39122233: Disconnect switch

UNSPSC 39122233 Disconnect Switch (Commodity) covers electrical switching components and related installation services that state and local governments procure for infrastructure upgrades, operational maintenance, and system replacements. Recent solicitations reveal a mix of network-infrastructure switch installations, electrical equipment procurement for facilities and transit systems, and specialized components including float switches, contact kits, and fuses used in water treatment, HVAC control, and industrial applications. The work spans both as-needed purchasing of standard electrical supplies and turnkey replacement projects requiring installation labor, expertise, and materials coordination.

Issuing bodies include city airports, transit authorities, water districts, school districts, county water resources departments, and state criminal-justice facilities. The City of Atlanta Department of Aviation, Dallas Area Rapid Transit Authority (DART), Hillsborough County Water Resources Department, and various school districts appear as repeat buyers. Geographically, recent activity concentrates in Texas (Dallas DART procurement, TDCJ, Northside Independent School District San Antonio), Florida (Hillsborough County, Orange County Transportation Authority), Georgia (Gordon County School System, Bibb County Public Schools), with secondary activity in Connecticut, Oregon, North Carolina, and Minnesota. Representative solicitations include the City of Atlanta's IFB for NEMA switch replacement at Hartsfield-Jackson International Airport with labor and materials due August 3, 2026; Hillsborough County's ITB for Square D brand contact kits ($184,000 estimated value over two years, due February 24, 2026); and the City of Dallas's sixty-month ID/IQ master agreement for electrical supplies across multiple product groups due March 13, 2026. DART has posted multiple narrow-window purchase orders for discrete components (10A traction power fuses, power converters, obstruction light assemblies) with response deadlines of four to six days. Several school districts are leveraging E-Rate funding for network switch upgrades with RFP structures, and water agencies are procuring specialized float switches for pump-control applications through competitive bidding with firm pricing and CPI-U adjustment provisions.
