Full Description

Scope

The scope of this standard is to provide requirements for low-voltage (600 V (ac) and below) definitepurpose switching (DPS) devices (other than power circuit breakers) for use in metal-enclosed, lowvoltage, power circuit breaker switchgear described in IEEE Std C37.20.1(TM)-2002.1 These switching devices may be used in motor control or other repetitive duty applications and have the following characteristics:a) Drawout type, three-pole constructionb) Integral current-limiting fuses for short-circuit protectionc) Power operated, with integral or separately mounted overcurrent protective deviceIn this standard, the term DPS device denotes a definite-purpose switching device conforming to the requirements of this standard.

Purpose

This standard provides guidance in evaluating switching devices, other than low-voltage power circuit breakers conforming to IEEE Std C37.13(TM), that are intended to be applied in metal-enclosed, low-voltage power circuit breaker switchgear.

Abstract

New IEEE Standard - Inactive - Superseded.This standard covers definite purpose switching devices for use in metal-enclosed low-voltage power circuit breaker switchgear. The switching devices shall be fused, drawout type, three-pole construction, with one or more rated maximum ac voltages of 600 V, 508 V, and 254 V for application on systems having nominal ac voltages of 600 V, 480 V, and 240 V. The switching devices are power operated with integral or separately mounted overcurrent protective devices. This standard addresses service conditions, ratings, functional components, temperature limitations and classifications of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application. The switching devices are normally used in applications that require frequency of operation greater than normal operations expected of low-voltage power circuit breakers.
