لوازم جانبی MCCB: با ولتاژ پایین، اتصال AC230V، AC380V، DC240V، DC 24V، با سیم کشی یا ترمیال

عملکرد

Realize the under-voltage protection function of the circuit breaker, open the circuit breaker when the 
power supply voltage is too low, and protect the electrical equipment.
 When the supply voltage drops (even slowly) to 70% to 35% of the rated control supply voltaage, 
the under voltage, the undervoltage trips, the breaker should open the circuit breaker reliably.
 When the supply voltage is equal to or greater than 85% of the rated control supply voltage of the 
undervoltage release, the circuit breaker should be guaranteed to close.
 When the supply voltage is less than 35% of the rated control supply voltage of the undervoltage 
release, the undervoltage release should prevent the circuit breaker.
