That useshall comply with the national regulations.This European Standard is not applicable to? sticks covered by EN 60832,? telescopic sticks covered by EN 62193,? sticks with mobile internal or external operating rods, as those used directly for fuse replacement,? single purpose sticks, especially designed to cover a single operation, generally as a completeequipment such as voltage detectors covered by EN 61243-1.NOTE Except where otherwise specified, all the voltages defined in this European Standard refer to values of phase-to-phasevoltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages shouldbe used to determine the operating voltage.【中国标准分类号】: K15【国际标准分类号】: 13_260【页数】: 42P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
