UNSPSC 39122301: Buchholtz relay

A relay used to protect against internal defects of transformer.

UNSPSC 39122301 Buchholtz relay is a Commodity code that encompasses electrical control and switching components used in water and wastewater infrastructure, though recent state and local opportunities show the code is being applied to a broader array of motor control and SCADA modernization work rather than Buchholtz relays specifically. State and local governments are soliciting replacements, upgrades, and maintenance services for motor control centers (MCCs), programmable logic controllers (PLCs), soft-start drives, and associated electrical control enclosures serving pump stations, lift stations, and water treatment facilities. Issuing bodies include county water districts (Hillsborough County, Bay County, West Basin Municipal Water District in California), city utilities departments (Tampa, Orlando, Santa Fe, Bartow), and school districts (Northside Independent School District). The procurement mix spans full-replacement projects, renovation and modernization contracts, single-source authorized-distributor arrangements for proprietary equipment maintenance, and cooperative purchasing vehicles aggregating demand across multiple jurisdictions.

Recent activity concentrates in Florida and the Southwest. Hillsborough County Board of County Commissioners issued ITB 26-00393 for pump station control panels and other enclosures with an estimated value of $3.66 million over two years and a September 29, 2026 deadline; ten contractors submitted bids ranging from approximately $2.5 million to $5.1 million. The City of Tampa's Wastewater Department filed an Intent to Single Source for Solcon Soft-Start replacement parts and services, with response due October 2, 2026. West Basin Municipal Water District in California issued RFBTH0120 for the TRWRP 93 Motor Control Center replacement with a mandatory pre-bid meeting on March 12, 2026 and bids due March 31, 2026.
