IEC TS 62271-319:2024适用于设计用于室内或室外安装以及在电压高于1000V的系统上以50Hz和60Hz的频率运行的有意非同时极性操作的交流断路器。本文件提供了此类断路器的额外额定值和型式试验，旨在与IEC 62271100:2021. 有意的非同步杆操作可以通过机械或电气方式实现，这两种方法都在本文件的范围内。

IEC TS 62271-319:2024 is applicable to alternating current circuit-breakers with intentional non-simultaneous pole operation designed for indoor or outdoor installations and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. This document provides additional ratings and type tests to be conducted for this type of circuit-breaker and is intended to be used in conjunction with IEC 62271？100:2021. Intentional non-simultaneous pole operation can be implemented by mechanical or electrical means and both methods are within the scope of this document.
