UNSPSC 39122322: Direct current voltage relay

A static relay that uses semiconductor. It is a relay that protects device or line by cutting off circuit or sounding alarm through highly sensitive detection of abnormal status of voltage during operation of direct current network system with capacity of less than DC300V.

UNSPSC 39122322 Direct current voltage relay is a Commodity code that encompasses electrical control components used in water treatment facilities, municipal water systems, electrical infrastructure upgrades, and industrial pump stations. State and local governments procure these relays as discrete components within larger electrical and mechanical system upgrades, control panel fabrication, motor control center replacements, and SCADA modernization projects. Recent solicitations show demand for relays integrated into motor control centers, soft starters, generator interconnections, and programmable logic controller replacements serving water reclamation, booster stations, and treatment facilities.

Water districts and municipal utilities dominate recent activity under this code, particularly the Eastern Municipal Water District (California), Orange County Water Reclamation (Florida), Hillsborough County Water Resources (Florida), and the Tucson Water Department (Arizona), alongside one state school district cooperative procurement and local government facilities. Geographic activity concentrates in California, Florida, and Arizona, with secondary activity in Georgia, North Carolina, and Oregon. Representative recent opportunities include the Eastern Municipal Water District's solicitation (RFPAR3928) for a medium voltage soft starter installation at Auld Road Booster Station with a May 9, 2026 proposal deadline; Orange County, Florida's invitation for bids (Y26604) for Eastern Water Reclamation Facility electrical and mechanical upgrades due April 30, 2026; the City of Santa Fe's RFP for PLC replacement and SCADA modifications to water treatment systems due January 9, 2026; and Hillsborough County Water Resources' invitation to bid (ITB2600138) for mercury float switches used in wells and lift stations, with a March 2, 2026 deadline and estimated two-year contract value of $60,000.
