断路器型号、级数、脱扣器额定电流、周围空气参考温度、接线方式、附件种类和附件额定工作电压。
Type of circuit Breaker, pole number, rated current of tripping device, reference temperature of ambient air mode of connection, kind of accessories and their working voltage ratings.

当电容器上所施加电压高于额定工作电压时,电容器的漏电流将上升,其电气特性将在短时内劣化直至损坏。
When capacitor is used at higher voltage than the rated voltage, leakage current increases, characteristics drastically deteriorate and damage in a short period may occur as a result.
