UNSPSC 39121645: Oil circuit breaker

A type of circuit breaker that switches on and off electric circuit. It has the circuit breaking part immersed in insulating oil, and it is referred to as the oil circuit breaker or OCB or Oil Circuit Breaker.

UNSPSC 39121645 Oil circuit breaker is a Commodity code describing electrical switching and protection equipment that state and local governments procure for utility infrastructure, water treatment facilities, wastewater systems, and correctional facilities. Solicitations under this code range from replacement of existing 15 kV oil circuit breakers at utility substations to procurement of outdoor vacuum circuit breakers rated at 15 kV and 2000 amps for municipal power systems. The issuing bodies include utility authorities, county water and wastewater departments, school districts seeking electrical supplies, state corrections agencies, and municipal electric utilities across Florida, Texas, Mississippi, Georgia, Michigan, Wisconsin, and Virginia. Scope varies from single emergency replacements (such as a 1600 AMP air circuit breaker swap at a state correctional facility) to framework agreements supporting multi-facility maintenance across county systems, and from material-only purchases to comprehensive installation and warranty work performed by licensed electrical contractors.

Recent activity shows solicitation diversity reflecting the distributed nature of state and local electrical infrastructure. The Kissimmee Utility Authority (KUA) in Florida issued IFB #17-003-CV for replacement of four 15 kV oil circuit breakers with three owner-furnished vacuum circuit breakers at Marydia Substation, with bids due November 15, 2016, and two vendors competing for the approximately $74,700 contract; Lubbock Power & Light in Texas posted RFP #7137-26-ELD for three outdoor vacuum circuit breakers rated 15 kV, 2000 A, with proposals due September 24, 2026, emphasizing delivery schedule and life-cycle cost in evaluation; and Fairfax County, Virginia's Department of Procurement & Material Management issued IFB 2000004382 for a five-year switchgear testing and preventative maintenance contract covering circuit breakers and motor control centers at eight facilities, with sealed bids due June 9, 2026. The Illinois Department of Corrections procured emergency replacement and installation of a damaged 1600 AMP air circuit breaker at Dixon Correctional Center under small purchase with emergency conditions, with a not-to-exceed contract value of $26,520 and completion by June 30, 2027. Geographic concentration is strongest in Florida (utility authorities, county systems), Texas (municipal utilities), and the upper Midwest and Mid-Atlantic (county wastewater and water treatment operations), with scattered activity in Georgia, Mississippi, and Illinois. Prevailing wage, Davis-Bacon compliance, and E-Verify requirements appear in several procurements; no specific DBE or SBE set-asides dominate the code, though Hillsborough County identified an SLBE-certified vendor directory entry.
