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。
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。
In case of the operation voltage less than 35% of the rated voltage, the under-voltage should prevent the breaker from closing.
敬告：欠电压脱扣器必须先通电，断路器才能再扣及合闸。否则将损坏断路器！
Caution: under-voltage release must be electricity, circuit breaker can be closed, otherwise will damage circuit breaker!
在额定控制电源电压的35%～70%时，欠电压脱扣器应可靠使断路器脱扣；
Under the voltage of 35% ~ 70% of the rated voltage, the under-voltage release should make the breaker trip correctly.
欠电压脱扣器在万能式断路器上是十分常见的一件电压保护装置，该装置的失效直接影响到断路器的正常运行。
An undervoltage tripper is a very popular electrical protection device for universal breaker, which will directly affect the normal operation of a breaker if it breaks down.
