UNSPSC 32121609: Fixed resistors

UNSPSC 32121609 Fixed resistors is a Commodity code that encompasses electrical protection relays, motor control centers, control panels, and related electromechanical switching components installed in water and wastewater utility infrastructure, SCADA systems, and facility electrical distribution networks. State and local governments procure these components primarily through utility authorities, county public works departments, and municipal water treatment facilities for replacement of aging protection systems, pump station controls, and electrical infrastructure upgrades. Recent solicitations show utilities standardizing on specific relay platforms—such as Schweitzer Engineering Laboratories (SEL) 451 and 751 protection relays—to maintain interoperability with existing SCADA environments, standardized protection schemes, and communications protocols without requiring costly redesign or retraining.

Kissimmee Utility Authority in Florida issued a sole-source RFQ (SS26054SH) in September 2026 for SEL 451 and 751 protection relays, justifying single-source procurement on the grounds that alternate relay platforms would require extensive SCADA redesign and operational risk. Hillsborough County Board of County Commissioners issued a competitive ITB (ITB-26-00393) in August 2026 for pump station control panels and enclosures across county facilities, valued at $3.66 million over two years, requiring UL 508A certification and weekly fabrication of two to four complete panels; ten contractors bid, with unit prices ranging from approximately $21,000 to $112,000 depending on electrical configuration. Gwinnett County, Georgia posted an RFQ (PA028-26) in June 2026 seeking approximately 200 units annually of 1500W metal halide ballasts and capacitors for Parks and Recreation operations. Trinity Metro in Tarrant County, Texas solicited an IDIQ electrical parts supplier contract (IFB26T035) in July 2026 to furnish electrical materials for maintenance and emergency operations across transit facilities. The code shows activity concentrated in Florida counties and Texas transit authorities, with additional procurement from Georgia municipal and utility jurisdictions.
