This is a Request for Information (RFI) document that provides responses to supplier inquiries regarding specific catalog numbers and technical specifications for high voltage switches and related components required under Solicitation Switches0001. The RFI clarifies that S&C Electric brand items require specific catalog numbers to generate accurate quotes, as the supplier manufactures multiple models for each requested item. The document provides the following catalog number answers: CLIN 0001 requires catalog number 55152R4; CLIN 0002 has been separated into two line items with catalog number 65E Fuses (613065 - 7 each) and CLIN 0003 with catalog number 80E Fuses (613080 - 9 each); and CLIN 0004 is associated with catalog number 3097, which was previously CLIN 0003 in the original solicitation. The RFI also notes that CLIN 0003 is rated at 15 kV but requires amperage specification, and clarifies the relationship between the original and revised CLIN structure following Amendment 2 to the solicitation dated April 8, 2026.
