This is a Statement of Work and Specifications document for the procurement of vacuum circuit breakers (VCBs) by the U.S. Army Corps of Engineers Nashville District for Center Hill Power Plant. The government intends to acquire one brand new 150VCP-WG-50-3000A Eaton vacuum circuit breaker as the base contract, with an option to award a second identical unit. The contractor must furnish and deliver within 180 calendar days of contract award. The VCB must be designed to work with EATON VacClad-W Metal-Clad Switchgear and replace part number 3759A72H12, meeting specific ANSI standards including 15 KV maximum voltage, 3000 amperes continuous current at 60 Hz, 50 KA short circuit current rating, and 10,000 mechanical endurance cycles. The equipment must be brand new, adequately packaged to preserve manufacturer condition, and include standard features such as motor cutoff switch, latch check switch, auxiliary switches, and ground contract assembly.

The contractor is responsible for all transportation, delivery, and storage costs included in the proposal price. Delivery must occur at USACE Center Hill Dam, 270 Lancaster Road, Lancaster, Tennessee 38569, Monday through Thursday, 0700-1530 hours, excluding federal holidays, with one week advance coordination required.
