低压开关设备和控制设备.第1部分:总则

[中文适用范围]： 当相关产品标准有要求时，适用于以下简称“设备”且用于连接至额定电压不超过 1 000 V 交流或 1 500 V 直流的电路的开关设备和控制设备。 [外文原描述]： Applies, when required by the relevant product standard, to switchgear and controlgear hereinafter referred to as "equipment" and 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. It does not apply to low-voltage switchgear and controlgear assemblies which are dealt with in IEC 60439. The object of this standard is to state those general rules and requirements which are common to low-voltage equipment as defined in 1.1, including for example: - definitions; - characteristics; - information supplied with the equipment; - normal service, mounting and transport conditions; - constructional and performance requirements; - verification of characteristics and performance
