UNSPSC 39121640: Hydraulic circuit breaker

UNSPSC 39121640 Hydraulic circuit breaker (Commodity) represents equipment replacement and installation work at utility substations, water treatment facilities, and correctional institutions. State and local governments procure circuit breakers and associated electrical switchgear primarily through their utility authorities, county departments of corrections, water and wastewater agencies, and facility management divisions. The work involves removing and installing new breaker units rated for specific voltages and amperage loads, often as part of substation modernization or emergency replacement projects. Contractors performing this work must hold appropriate electrical licenses, maintain insurance at statutory minimums, and comply with National Electrical Code standards and facility-specific safety protocols, including work restrictions in energized substations and coordination with facility operations managers.

Recent opportunities cluster in Florida, Texas, Mississippi, and other states with active utility infrastructure maintenance. The Kissimmee Utility Authority issued IFB #17-003-CV for the Marydia Substation 15 kV circuit breaker replacement in October 2026, selecting Terry's Electric Inc. at $74,710.27 for removal of four oil circuit breakers and installation of three owner-furnished Square D Type FVR units with control cable work. Lubbock Power & Light released RFP #7137-26-ELD in August 2026 (proposal due September 24, 2026) for three outdoor vacuum circuit breakers rated 15 kV, 2000 A with protective relays and current transformers for installation at the Erskine Substation. The Illinois Department of Corrections issued a small purchase with emergency conditions in July 2026 (due July 16) for replacement of a damaged 1600 AMP air circuit breaker at Dixon Correctional Center, capped at $26,520 with a one-year warranty requirement. Broward County and Fairfax County issued parallel procurements for control panel fabrication, refurbishment, and switchgear testing and preventative maintenance in May–June 2026, which encompass circuit breaker assessment and replacement within broader electrical system maintenance scopes. These solicitations typically run 30–60 days and award to the lowest responsive, responsible bidder under sealed bidding formats, with work commencement within weeks to months of award.
