About this file
This document is a technical data sheet for a medium voltage circuit breaker procurement for Boulder City Substation #3, involving three 12.5kV 2000A circuit breakers. The project, identified with project number 185915, is scheduled for quote on 7/16/25 and involves transformer switching equipment with no specified field services requirement. The procurement calls for three circuit breakers with specific electrical specifications, including a rated maximum voltage of 15.5 kV, a rated continuous current of 2000A, and a rated short-circuit current of 25 kA.
The technical specifications outline detailed electrical parameters including basic impulse lightning level of 110 kV peak, a system neutral that is effectively grounded, and a power-frequency withstand voltage of 50 kV. Environmental service conditions are specified as an ambient temperature range of -30°C to +40°C for normal climates. The circuit breakers are classified as S2 with a first pole to clear factor of 1.5, and suppliers are expected to provide specific details on capacitor current switching rating and TRV envelope parameters. No specific pricing, funding sources, or contract terms beyond the technical specifications are included in this data sheet.
