Full Description

Scope

This standard covers metal-enclosed low-voltage power circuit breaker switchgear assemblies containing, but no limited to, such devices as low-voltage power circuit breakers (fused or unfused); other interrupting devices; switches, control, instrumentation, and metering; and protective and regulating equipment. This standard is concerned with enclosed, rather than open, indoor and outdoor switchgear assemblies. It includes types of equipment that are part of secondary unit substations. It does not apply to equipment covered by industrial control standards, communication switchboards, comminication switching equipment, switchboards for use on board ships, or dead-front distribution switchboards. In this standard, metal-enclosed low-voltage power circuits breaker switchggear shall be called LV switchgear. For ac LV switchgear, the voltage shall be 1000 V or below; for dc LV switchgear, the voltage shall be 3200 V or below.

Abstract

New IEEE Standard - Superseded.The standard covers metal-enclosed interrupter switchgear assemblies containing such devices as interrupter/switches, selector switches, power fuses and protective equipment. It is concerned with enclosed, rather than open, switchgear assemblies rated above 1000 V used for the distribution of electrical power. It includes equipment that is part of primary and secondary unit substations.
