Certificates

You can find information on the available certification (CE, UL, CSA, FM, marine approvals)
on the Internet (http://support.automation.siemens.com/WW/view/en/54137334/134200).
In the Entry List you can use the certificate type (general product approval, explosion
protection, test certificates, shipbuilding, etc.) as a filter criterion.
2.5.4

Ambient conditions

Pollution degree
Operation of the 3VA1 and 3VA2 molded case circuit breakers is approved in accordance
with IEC / EN 60947-1 and IEC / EN 60664-1 for pollution degree 3.
Ambient temperature
3VA molded case circuit breakers are used at ambient temperatures from -25 °C to +70 °C.
Derating (reduction in rated operational current) is required at temperatures above +50 °C.
You will find more information on the applicable derating factors in chapter Derating and
temperature compensation (Page 489).
The permissible storage temperature in original Siemens packaging lies between -25 °C and
+80 °C.
Special climatic requirements
3VA molded case circuit breakers including their accessories can also be used in
challenging operating environments.
