I 기능
To realize the under-voltage protection function of the circuit breaker, the circuit breaker should be disconnected when the power supply voltage is too to protect the electrical equipment.
◆When the power supply voltage drops (or slowly drops) to the range of 70% to 35% of the rated control supply voltage, the under-voltage trip should reliably open the circuit breaker.
◆When the power supply voltage is equal to or greater than 85% of the rated power supply voltage of the under-voltage trip, the circuit breaker should be guaranteed to be closed.
◆When the power supply voltage is lower than 35% of rated control power supply voltage of the under-voltage trip, the under-voltage trip should prevent the circuit breaker from closing.
