UNSPSC 39121012: Chokes

UNSPSC 39121012 Chokes is a Commodity code covering electrical protection and control components—specifically electromagnetic chokes, relays, solenoids, ballasts, capacitors, and related electrical parts used in industrial control systems, power distribution infrastructure, and facility maintenance. State and local governments procure these components primarily through utility authorities, county public works and water departments, transit authorities, and school districts for replacement, maintenance, and emergency repair of electrical systems, control panels, SCADA infrastructure, and building facilities. Recent solicitations show demand for specialized relay systems compatible with existing standardized protection schemes, motor control center components, electrical parts inventories for maintenance operations, and branded electrical components for standardized procurement frameworks.
