Signal control cable applied the copper cored cable which may withstand 500 AC rated voltage.
信号控制电缆采用能耐交流额定电压500伏以上的铜芯电缆。
At rated control supply voltage less than 35% under-voltage should prevent breaker from closing.
在额定控制电源电压低于35%时，欠电压脱扣器应防止断路器合闸。
It is applicable for control, monitoring circuit and protective circuit of rated voltage up to and including 450/750V, used in the anti-flaming location which requires environment protection.
用途 Usage 适用于使用交流额定电压450/750及以下控制、监控回路及保护线路等有一定环保要求的阻燃场合。
