IEEE 1247-2005 pdf download IEEE Standard for Interrupter Switches for Alternating Current, Rated Above 1000 V
1. Overview
1.1 Scope
This standard applies to switching devices, interrupters, and interrupter switches (as defined in lEEE StdC37.100″) for alternating current, rated above 1000 V and used indoors, outdoors, or in enclosures forwhich a switching rating is to be assigned. While this standard covers the basic requirements of interrunterswitches used indoors, outdoors, and in enclosures, other standards such as lEEE Std C37.20.2”. IEEE StdC37.20.3″”, IEEE Std C37.20.4, and 1EEE Std C37.74 also contain requirements for switches used inenclosures. This standard does not apply to load-break separable insulated connectors, which are coveredby IEEE Std 386-1995 (B8). This standard also does not apply to circuit-breakers, circuit-switchers, orreclosers.
1.2 Purpose
The purpose of this standard is to provide a basic standard for switches as defined in 3.5. The broaddefinition of a switch, given in 3.5, encompasses devices that meet the strict definition of an interrupterswitch in lEEE Std C37.100, and also encompass devices that utilize insulating media other than air.
