IEC 63024:2017适用于家用和类似用途的自动重合闸装置（ARD），额定电压不超过440？V AC，旨在与断路器、RCCB和RCBO结合使用，并设计用于工厂组装或现场组装。 这些装置用于重合闸主保护装置（MPD），如符合IEC？60898-1和/或IEC？60898-2，符合IEC的RCCB？61008-1和/或IEC？62423，以及符合IEC的RCBO？61009-1和/或IEC？62423在这些设备跳闸后，以便重新建立服务的连续性。

IEC 63024:2017 applies to automatic reclosing devices (ARDs) for household and similar uses, for rated voltage not exceeding 440？V AC, and which are intended to be used in combination with circuit-breakers, RCCBs and RCBOs, and designed either for factory assembly or for assembly on site.
These devices are intended to reclose main protective devices (MPDs) such as circuit-breakers complying with IEC？60898-1 and/or IEC？60898-2, RCCBs complying with IEC？61008-1 and/or IEC？62423, and RCBOs complying with IEC？61009-1 and/or IEC？62423 after tripping of those devices in order to re-establish continuity of service.
