Description de Produit


Low Voltage Circuit Breakers Air 1600A, 2000A, 2500A, 3200A Dw45Low Voltage Circuit Breakers Air 1600A, 2000A, 2500A, 3200A Dw45

DAA series Low Voltage
Air circuit breaker air circuit breaker is suitable for the circuit of AC 50Hz/60Hz with rated service voltage 400V, 690V and rated service current up to 6300A.It is mainly used to distribute  electric energy and protect  circuits and electric equipment against  over-load, under-voltage, short-circuit and single-phase  earthing  fault.

With intelligentized  and selective protection functions,  the breaker can improve the reliability of power supply, and avoid unnecessary power failure.The breaker is applicable for power stations,  factories, mines (for 690V) and modern  high- buildings, especially for the distribution  system of intelligentized  building.

 



·Advantages provided for design and manufacture of LV assemblies

>> With high short-circuit breaking capacity,Non ionization distance

380/400V80-120kA
660/690V50-85kA

>> Perfect intelligent protective functions.
The electronic trip unit is a microprocessor based techniques with intelligent protective functions.

>> All modular structure
Modular design for whole series,simple maintenance and adjustment free.

>> Double insulation, safe and reliable
Double insulation from the front face of the circuit breakers, operated safely and reliably.

>> Compact design, Light in weight
