Full Description

Scope

This standard covers the following types of enclosed low-voltage dc power circuit breakers:a) Stationary or draw-out type of one- or two-pole construction;b) Having one or more rated maximum voltages of 3200 V, 1600 V, 1000 V, 800 V, 325 V, or 300 V forapplications on systems having nominal voltages of 3000 V, 1500 V, 850 V, 750 V, 275 V, or 250 V;c) Manually-operated or power-operated;d) With or without overcurrent trip devices

Abstract

Revision Standard - Superseded.This standard covers enclosed low-voltage dc power circuit breakers of the stationary or drawouttype of single- or two-pole construction with one or more rated maximum voltages of 300 V, 325 V, 800 V, 1000 V, 1600 V, or 3200 V for applications on dc systems having nominal voltages of 250 V, 275 V, 750 V, 850 V, 1500 V, or 3000 V, with general-purpose, high-speed, semi-high-speed and rectifier circuit breakers; manually or power-operated; and with or without electro-mechanical or solid-state trip devices. It deals with service conditions, ratings, functional components, temperature limitations and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application.
