低压开关设备与控制设备的IEC标准与UL标准对比分析

Contrastive Analysis of the Standards of IEC and UL on Low Voltage Switchgear and Controlgear

对比分析了世界上最受公认并影响着低压开关设备和控制设备的设计和应用的两大系列标准即IEC标准与UL标准 。

Some contrastive analysis of the IEC standards and UL standards for low voltage equipment were introduced so as to provide a better understanding of their content and impact on the design and selection of products for application in electric power systems. The main content of contrastive analysis included: circuit breaker, switch, isolator , fuse, contactor and motor starter, automatic transfer switching equipment.
