6.1. Storage and operation conditions
The molded case circuit breakers VA-99M shall be stored in the original package
indoors with natural ventilation at ambient air temperature from -60 to +55°С
and relative humidity up to 80% at +25°С.
The molded case circuit breakers can be operated at temperatures between
-25°C and +40°C.
The average temperature during 24 hours shall not exceed +35 °C.
Altitude above sea level shall not exceed 2000 meters.
Pollution degree: III.
The device supports connection of alumiuim and copper wires. Do not coneect
copper and aluminium wires to one terminal at the same time.
Degree of ingress protection (according to IEC 60529:2013): IP30 - circuit
breaker housing; IP00 - terminals for connection of external conductors.
At the air temperature of +40 °C, the relative humidity shall not exceed 50%.
The relative humidity may be higher at lower air temperatures. The maximum
monthly average relative humidity shall not exceed 90% in the wettest month
at the lowest monthly average temperature of +25°C. Be aware that sudden
changes in temperature can lead to condensation on the surface of the molded
case circuit breaker.
