家用和类似应用的电力过电压保护装置（POP

[中文适用范围]： 本文件适用于额定频率为 50 Hz、60 Hz 或 50/60 Hz，额定电压不超过 230 V（相与中性线之间），额定电流不超过 63 A，由功能单元与主保护设备组合而成，或作为具有可在特定条件下断开保护电路的断开机构装置的单个设备，用于家庭和类似用途的工频过压保护设备（以下简称"POP"）。 主保护设备为断路器、剩余电流动作保护器（RCCB）或带过电流保护的剩余电流动作断路器（RCBO）。 POP 适用于污染等级 2 和过电压类别 III 的环境。 POP 旨在通过断开保护电路来减轻工频过电压（例如由上游三相供电中性线丢失引起）对下游设备的影响。 本文件不适用于共模过电压保护和浪涌保护器的保护。 [外文原描述]： IEC 63052:2019 applies to devices for power frequency overvoltage protection (hereafter referred to as "POP") for household and similar uses, with a rated frequency of 50 Hz, 60 Hz or 50/60 Hz, with rated voltage not exceeding 230 V AC (between phase and neutral), and with rated current not exceeding 63 A, either consisting of a functional unit in combination with a main protective device (MPD), or as one single device having opening means able to open the protected circuit in specified conditions. The main protective device is a circuit-breaker, an RCCB or an RCBO. The contents of the corrigendum of November 2019 have been included in this copy.
