UNSPSC 39122301: Buchholtz relay

A relay used to protect against internal defects of transformer.

UNSPSC 39122301 Buchholtz relay, a Commodity code, does not align with recent state and local solicitation activity. The code nominally covers electromechanical protective devices, but the recent opportunities tagged under this code—spanning electrical equipment parts procurement, water district upgrades, school district safety items, and network infrastructure installation—name no Buchholtz relays, protective relays as a primary line item, or electromechanical switching devices. The only solicitation with direct relevance to protective relay technology is Orange County, Florida's IFB Y26-604 for Eastern Water Reclamation Facility electrical upgrades (due April 30, 2026), which includes replacement of protective relays with Schweitzer microprocessor-based units as a subordinate component of a larger motor control center and switchgear retrofit. No state or local procurement body has issued a standalone solicitation for Buchholtz relays in the recent activity block.

The code shows little relevant activity across issuing bodies. Water districts, counties, and school districts appear in the broader electrical equipment and supplies opportunities, but none target the narrow commodity of Buchholtz relays. Geographic spread includes Texas (Northside Independent School District), Florida (Orange County, Town of Palm Beach, Hillsborough County), California (West Basin, EMWD), Oregon (Salem), Arizona (Tucson), North Carolina (Charlotte), New Mexico (Santa Fe), Minnesota (Sourcewell cooperative), and Georgia (Bibb County), but activity concentrates on general electrical parts stocking contracts, water treatment system upgrades, and network infrastructure rather than protective relay procurement. The code presents limited pursuit opportunity in the current market.
