IEEE C37.20.1-2002

Description

Revision Standard – Superseded.Low-voltage metal-enclosed switchgear-which contains either stationary or drawout, manuallyor electrically operated low-voltage ac or dc power circuit breakers in individual grounded metalcompartments, in three-pole, two-pole, or single-pole construction is covered. Rated maximum voltagelevels are 254V, 508V, or 635V (ac) and 300/325V, 800V, 1000V, 1200V, 1600V, or 3200V (dc). Thepreferred continuous current ratings of the main bus in ac designs are 1600A, 2000A, 3000A, 3200A,4000A, or 5000A. For dc designs, the preferred ratings are 1600A, 2000A, 2500A, 3000A, 4000A, 5000A,6000A, 8000A, 10000A, or 12000A. The switchgear may also contain associated control, instruments,metering, protective, and regulating devices as necessary. The standard deals with service conditions, ratings, temperature limitations, and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application.
