Outline and Installation Dimension:

Working condition:
1.The altitude not exceeding 2000m
2.The ambient temperature is from +40°Cto -5°C
3.Ambient environment is free from explosive danger and air or dust, which may cause corrosion of metal or weakness of insulation.
4.Ambient environment is free from erosion of rain or snow.
5.Pollution degree 3
6.Over-voltage category III

Trip characteristic:
The thermodynamic release of the breaker has the advantages of inverse time-delay while the magnetic release the instantaneous operation as shown on table 2(distribution circuit breaker)and table 3(motor protection circuit breaker).
