   DW45 series 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.

 

2) Operation conditions

2.1 Temperature condition:  -5°C~40°C;the average value within 24h shall not exceed +35°C(special situation  excluded);

2.2 Altitude:≤2000m;

2.3 Pollution grade:  Grade 3;

2.4 Air conditions:

At mounting site, relative humidity not exceed 50% at the max temperature of +40°C, higher relative humidity is allowable under lower temperature,RH could be 90% at +20°C, special measures  should be taken to occurrence of dews.
