UNSPSC 39122320: Horizontal relay

A relay used widely for strowger type automatic switchboard. It is an electromagnetic relay in the format of contact point spring moving in horizontal direction with characteristics of being multi-contact point type.

UNSPSC 39122320 Horizontal relay is a Commodity code that covers discrete electrical components used in control and switching applications within municipal water and wastewater systems, school district facilities, and transportation infrastructure. State and local procurement activity under this code shows limited direct solicitation for relays as standalone products; instead, horizontal relays and related control components appear embedded within broader electrical equipment, parts, and supplies contracts or as subcomponents of larger motor control and SCADA system upgrades. Recent opportunities show school districts, water utilities, and municipal facilities procuring electrical control systems that incorporate relays and soft starters as functional elements rather than discrete line items.

The issuing-body mix reflects municipal water districts, county utilities, independent school districts, and municipal public works departments. Water utilities dominate recent activity—Eastern Municipal Water District (Riverside County, California), Hillsborough County Water Resources Department (Florida), and West Basin Municipal Water District (California) have posted solicitations for medium voltage soft starters, float switches, and motor control center replacements that integrate relay logic. Independent school districts including Northside Independent School District (San Antonio, Texas) and Cache County School District (Utah) solicit electrical equipment packages, while municipality-level buyers such as Orange County, Florida and the City of Phoenix procure electrical parts on blanket-supply contracts. Geographic concentration is heaviest in California and Florida, with secondary activity in Texas, Utah, and Georgia. Representative recent opportunities include Eastern Municipal Water District's RFP for medium voltage soft starter installation at the Auld Road Booster Station (proposal due May 8, 2026); West Basin Municipal Water District's RFB for motor control center replacement at the Torrance Refinery Water Reclamation Plant in California (due March 31, 2026); and Hillsborough County Water Resources Department's ITB for mercury float switches and Square D contact kits (mercury float switches due March 2, 2026; contact kits due February 24, 2026, with estimated contract value of $184,000 for the two-year term).
