UNSPSC 39121644: High speed circuit breaker

Circuit breaker with high speed of circuit breaking, which can prevent damages to devices as it can completely prevent flashover in the event of short circuit.

UNSPSC 39121644 High speed circuit breaker is a Commodity code covering the replacement, installation, and supply of high-speed circuit breakers rated at medium to high voltages (typically 15 kV and above) used in utility substations, water and wastewater treatment infrastructure, and correctional facilities. Recent state and local solicitations under this code focus on the removal and installation of existing circuit breakers with owner-furnished or contractor-supplied replacements, often paired with control wiring, protective relays, and factory testing. The buying base spans utility authorities, county boards of commissioners, municipal water and wastewater operators, school districts, and state correctional agencies—with significant recent activity among Florida utilities and multi-county water service providers. Work commonly includes vacuum or oil circuit breaker replacement at substations and pump stations, integration with modern supervisory control and data acquisition (SCADA) systems, compliance with National Electrical Code and NFPA standards, and strict service-level requirements for emergency response and 24/7 availability.

Geographic concentration leans toward Florida, Texas, and the upper Midwest; the Kissimmee Utility Authority (KUA) in Florida issued an IFB (IFB17003CV) in October 2026 for replacement of four 15 kV oil circuit breakers and installation of three Square D Type FVR 1200-ampere vacuum circuit breakers at the Marydia Substation, with responses due November 15, 2016 (response due dates in source materials reflect archival data spanning 2016–2026). Lubbock Power & Light in Texas solicited proposals for three outdoor 15 kV, 2000A vacuum circuit breakers with SEL protective relays and factory testing under RFP #7137-26-ELD, due September 24, 2026. The Illinois Department of Corrections issued a small purchase with emergency conditions for a one-time 1600 AMP air circuit breaker replacement at Dixon Correctional Center, due July 16, 2026. Hillsborough County, Florida procured pump station control panels and related electrical enclosures under ITB-26-00393 (estimated $3.66 million over two years, extended deadline September 29, 2026), requiring UL 508A certification and weekly fabrication and delivery cycles. Fairfax County, Virginia established a five-year switchgear testing and preventative maintenance contract (IFB 2000004382) for low- and medium-voltage equipment across wastewater treatment facilities, with bids due June 9, 2026. These solicitations typically carry prevailing wage and Davis-Bacon requirements when federally funded, mandatory site visits or pre-bid meetings, and insurance minimums of $1 million to $2 million general liability.
