9、 fuses and switches. Significant changes include the clarification and expan-sion of application areas that have been reported as causing some confusion. Some additional informationregarding the effect of ambient temperature on the current rating of a fuse has been added, as well as infor-mation reg
10、arding parallel fuses.This guide was prepared by the Revision of Fuse Standards working group of the IEEE Subcommittee onHigh-Voltage Fuses. Liaison was maintained with the International Electrotechnical Commission (IEC) dur-ing the development of the revisions in order to incorporate the latest act
11、ivities at the time of publication. Itis one of a series of complementary standards covering various types of high-voltage fuses and switches,arranged so that certain standards apply to all devices while other standards provide additional specificationsfor a particular device. For any device, IEEE S
12、td C37.40-2003, IEEE Std C37.41-2000, plus anyadditional standards covering that device, constitute a complete standard for the device. In addition, thisdocument provides application, operation, and maintenance guidance for all the devices, and is supple-mented by IEEE Std C37.48.1-2002, which is an
13、 operation, classification, application, and coordinationguide for current-limiting fuses.The following standards make up this series: ANSI C37.42-1996, American National Standard Specifications for High Voltage Expulsion Type Distribu-tion Class Fuses, Cutouts, Fuse Disconnecting Switches and Fuse

44、BackgroundThe distribution class and power class expulsion-type fuses listed in 1.1 are similar to those now covered inIEC 60282-2. The distribution class expulsion-type fuses are similar to the class “A” fuses covered in theIEC document and the power class fuses are similar to their class “B” fuses
45、. At present, IEEE and ANSIstandards do not cover the class “C” fuses listed in the IEC standard. Some of the current-limiting type fuseslisted in 1.1 are similar to those now covered in IEC 60282-1. However, significant differences exist in thetesting requirements of IEC and IEEE/ANSI. IEEE fuse st
46、andards reflect, primarily, applications commonin North America, and in countries that use electrical systems designed using similar principles. IEC stan-dards tend to rely heavily on practices common in Europe. Since IEC testing differences include testing atdifferent voltages for the same fuse rat
47、ed voltage, and different or no testing for fuses intended for use in asurrounding temperature above 40 C, the user is advised to exercise extreme caution if devices specifiedand tested per IEC standards are compared to those specified and tested per IEEE/ANSI standards. The dif-ferences in test req
48、uirements may result in devices tested to IEC not being suitable for applications wheredevices tested to IEEE and ANSI standards are required, or vice versa. In the headings and the text of this document there will be some areas where information is included inbrackets . The information in the brack
49、ets is a term used in IEC standards that may be similar to the termused in this document, a term that is common in some parts of the world, or a term that has been used previ-ously in IEEE or ANSI standards. Caution is again advised when making comparisons.1.3 Description of fuse-enclosure packages (FEPs) using expulsion-type indoor power class fuses Type 1E: A fuse mounted in an enclosure with relatively free air circulation within the enclosure (forexample, an expulsion fuse mounted in an enclosure or in a vault) Type 2E: A fuse mounted
