| 摘 要： | 通常情况下,电气设计人员应根据MCB的常用电气参数选用塑壳断路器,对于不同性质的线路,要选用不同保护特性的MCB。当环境温度与MCB的校准温度值不同时,必须根据制造厂商提供的温度与载流能力修正曲线来调整MCB的额定电流值,并根据制造厂商提供的匹配表合理选用上下级MCB。

| Abstract: | According to electric general parameters of MCB,MCB of different protection feature can be selected for different properties circuit.Rating current value of MCB needs to be adjusted according to temperature and carrying current adjusting curve supported by when temperature around doesn't agree with the standard temperature of MCB,and it's also reasonably selected for up- down level MCB according to matching table supported by manufacturer. |
