C37.13-1990 - IEEE Standard for Low-Voltage AC Power Circuit Breakers Used in Enclosures

Description: The standard covers enclosed low-voltage AC power circuit breakers of the stationary or draw-out type of two or three-pole construction, with one or more rated maximum voltages of 635 V (600 V for units incorporating fuses), 508 V, and 254 V for application on systems having nominal voltages of 600 V, 480 V, and 240 V; with unfused or fused circuit breakers; manually or power operated; and with or without electromechanical or solid-state trip devices. It deals with service conditions, ratings, functional components, temperature limitations and classifications of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application.
