Воздушные автоматические выключатели — SW45 Series ACB 
Подробное описание
Designation
SW45 series intelligent air circuit breakers are applied for the network circuit of AC 50 / 60Hz, rated voltage 400V,690V and rated current between 630A and 6300A, mainly used for distribution energy and protecting the circuit and power supply device against short-circuit, under-voltage, single-phase ground fault, etc. The air circuit breaker has intelligent protection function and the key parts adopt intelligent release. The release can make the accurate selective protection, which can avoid cutting off the power and improve the reliability of power supply.
