标准范围
IEC 60947-4-1:20 09适用于其主触点打算连接到额定电压不超过1 000 V交流电的电路的设备类型。或1500V直流电。本标准中涉及的起动器和/或接触器通常不设计为中断短路电流。因此,适当的短路保护是装置的一部分,但不一定是接触器或起动器的一部分。这第三版取代了2000年出版的第二版及其修正案1(2002)和2(2005)。这是一次技术修订。与上一版(2000年)及其修正案1(2002年)和2(2005年)相比,本版本包括以下重大技术变更:-删除未补偿环境空气温度的热过载继电器在-5℃和+20℃下的测试;-根据IEC 60947-1附录Q增加试验条件;-EMC测试:澄清快速瞬态严重性级别的验收标准并与IEC 60947-1保持一致;-附录B,Icd测试:将介电测试电压的持续时间从5秒修改为60秒;-附件B,电气耐久性:改进统计方面;-附件H:澄清和介绍电子过载继电器中新的扩展功能;-附件K,确定功能安全应用中使用的机电接触器数据的程序:创建本新附件。本标准应与IEC 60947-1《低压开关设备和控制设备—第1部分:通则》一并阅读。如有特别要求,通则的规定适用于本标准。本出版物应与IEC 60947-1:20 07一起阅读。
IEC 60947-4-1:2009 applies to the types of equipment whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c. Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection forms part of the installation but not necessarily of the contactor or the starter. This third edition replaces the second edition published in 2000 and its Amendments 1 (2002) and 2 (2005). It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition (2000) and its Amendments 1 (2002) and 2 (2005):
- deletion of the test at -5 °C and +20 °C for thermal overload relays that are not compensated for ambient air temperature;
- addition of conditions of the tests according to Annex Q of IEC 60947-1;
- EMC tests: clarification of acceptance criteria and alignment with IEC 60947-1 for fast transient severity level;
- Annex B, test for Icd: modification of the duration of the dielectric test voltage from 5 s to 60 s;
- Annex B, electrical durability: improvement of the statistical aspects;
- Annex H: clarification and introduction of new extended functions within electronic overload relays;
- Annex K, procedure to determine data for electromechanical contactors used in functional safety applications: creation of this new annex. This standard shall be read in conjunction with IEC 60947-1, Low voltage switchgear and controlgear - Part 1: General rules. The provisions of the general rules are applicable to this standard, where specifically called for.
This publication shall be read in conjunction with IEC 60947-1 :2007.
