UNSPSC 39122302: Distance relay

A relay designed to set the time limit for motion in accordance with the normal impedance measured from the relay installation point to the point of defect by using voltage and current at the time of defect.

UNSPSC 39122302 Distance relay (Commodity) covers protective relay hardware and control equipment purchased by state and local jurisdictions, though recent solicitations under this code reflect broader electrical equipment procurement rather than distance relays narrowly. State and local buyers—water districts, municipalities, school districts, and counties—are soliciting relay replacement, motor control centers, switchgear upgrades, and soft-starter installations as part of larger infrastructure modernization projects. The Eastern Municipal Water District's medium-voltage soft-starter installation at Auld Road Booster Station (RFP issued April 11, 2026, due May 9, 2026) exemplifies work actually being bought: a 2400V, 97A, 450HP unit from authorized distributors (ABB, Allen Bradley, Solcon, Schneider Electric, or Toshiba) paired with installation, startup, and training. West Basin Municipal Water District's Motor Control Center Replacement (RFBTH0120, issued April 24, 2026, closed April 23, 2026) and Orange County, Florida's Electrical and Mechanical Upgrades at the Eastern Water Reclamation Facility (IFB Y26-604, revised due April 30, 2026) similarly bundle relay and protective-device procurement with installation and commissioning services. Northside Independent School District's broader electrical equipment RFB (IFB2026098, issued June 8, 2026, due July 1, 2026) does not isolate distance relays but includes them within general electrical parts supply.

Recent activity concentrates in California (West Basin, Orange County, Eastern Municipal Water District) and Florida (Hillsborough County, Orange County, Town of Palm Beach), with scattered opportunities in Texas, Oregon, and Georgia. Water utilities and municipalities dominate the buyer base, reflecting critical infrastructure replacement cycles. The code shows mixed relevance: while distance relays appear in spec lists for motor control center and soft-starter upgrades, most solicitations under this code actually procure broader electrical components and installation services rather than relays as standalone line items. Response deadlines from the active pool range from February through July 2026, with mandatory pre-bid meetings and question-submission windows typical for work exceeding several hundred thousand dollars.
