UNSPSC 39121631: High voltage oil filled circuit breaker

A type of automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Used in power transmission networks involving voltages of 72,500 volts or higher. Uses oil as an arc extinguishing medium.

UNSPSC 39121631 High voltage oil filled circuit breaker is a Commodity code describing discrete electrical switching and protection equipment that state and local utilities, water authorities, and correctional facilities procure for substation, distribution network, and facility electrical system upgrades and replacements. Recent opportunities show utilities and municipal authorities purchasing circuit breakers ranging from 15 kV to 161 kV rated systems, with work scopes including removal and installation of existing breakers, integration with protective relays and control systems, and compliance with NEC, NFPA, and facility-specific electrical codes. The issuing-body mix reflects utility operators (municipal electric utilities, county water and wastewater authorities), state facilities (correctional institutions), and academic institutions managing large electrical infrastructure. Kissimmee Utility Authority in Florida solicited IFB 17-003-CV for three 15 kV circuit breaker replacements at Marydia Substation, with two bids received and Terry's Electric, Inc. winning at $74,710.27; Lubbock Power & Light in Texas issued RFP 7137-26-ELD for three 15 kV outdoor vacuum circuit breakers with delivery by March 21, 2027; and Fairfax County, Virginia's IFB 2000004382 for a five-year switchgear testing and preventative maintenance contract across eight facilities encompasses low and medium voltage circuit breakers from 600V to 4160V.

Geographic activity concentrates in Florida (Kissimmee, Broward County, Hillsborough County), Texas (Lubbock, Dixon Correctional Center), and Virginia (Fairfax County), with scattered opportunities in Mississippi, Connecticut, and California. Recent solicitations emphasize technical rigor—vendors must hold UL 508A certification or equivalent, provide factory acceptance testing and as-built documentation, meet extended service-level commitments including 24/7 emergency response, and comply with prevailing wage and federal sourcing restrictions where applicable. Control panel fabrication and refurbishment—closely adjacent to discrete breaker procurement—appears in open-end contracts at Broward County (PNC 2132148B3 due June 22, 2026 for water and wastewater control panels with initial two-year term and three renewal options) and Hillsborough County (ITB 26-00393 for pump station control panels at $3.66 million over two years with weekly fabrication demands and 24/7 callout support). The code shows steady mid-market activity with contract values ranging from under $30,000 for single-unit replacements to $3.66 million for multi-year panel supply arrangements, and no uniform set-aside framework—some jurisdictions carry SLBE or DBE goals while others impose none.
