59 -- CONVERSION OF 600 VOLT AIR CIRCUIT BREAKERS FROM ELECTRO- MECHANICAL TRIPPING UNITS TO SOLID-STATE TRIPPING UNITS POC Linda P. Fitzgerald, Industry Assitance Office (804) 864-2461. Langley Research Center (LaRC) is considering converting 600 volt class air circuit breakers from electro-mechanical trip to solid-state trip and is also considering remanufacturing of 600 volt class air circuit breakers. Breakers under consideration to be converted include those manufactured by General Electric, ITE, Westinghouse, and Allis Chalmers from approximately 1950 to 1980 with frame sizes of 225, 600, 800, and 1600 amperes. Information is being sought on the availability of services to perform these functions. Companies that are interested in providing engineering data to be used when the specifications are being prepared are requested to submit (as a minimum) the following data: (1)Information on the proposed method of converting circuit breakers from electro-mechanical trip to solid-state trip and for remanufacturing circuit breakers. Information should include brochures, documentation, literature, remanufacturing details, testing requirements, national standards (such as IEEE and ANSI) that the converted breakers are required to meet, and budget estimates. Breaker with ratings of 225, 600, and 1600 amperes are to be considered. Estimates for converting to solid-state trips and for a complete remanufacture should be priced separately. (2)Information on any programs offered by your company for exchanging converted breakers with Government-owned circuit breakers or any loan programs while the Government-owned circuit breakers are being converted. (3)Information on maintenance anticipated for the converted breakers. Please submit the required information as stated above to NASA Langley Research Center, Industry Assistance Office, M/S 144, Hampton, VA 23681-0001. Technical questions regarding this requirement can be directed to Carl E. Horne, telephone (804) 864-7260. This information is for planning and designing purposes and is not to be construed as a commitment by the Government, nor will the Government pay for the information solicited. Respondents will not be notified of the results of the evaluation. Respondents deemed fully qualified will be considered in any resulting solicitation for the requirement. Firms responding should indicate whether they are a socially or economically disadvantaged business firm, an 8(a) firm, a small business, and/or woman-owned business. The Government reserves the right to consider a small or 8(a) set-aside based on responses hereto. All responses shall be submitted with 14 days from the date of publication of this announcement.
