    Describe 

    National standard gb 1208-2006;

    Industry Standard jbt 10665-2006.


    Use Temperature:-25℃-+85℃

    Relative humidity:≤95%


    Scope of application:It is suitable for use in intelligent circuit breakers, leakage protectors, etc. for leakage protection.


    Note:

    If a load connected to the transformer secondary that exceeds the rated load capacity may cause saturation, reduce consistency. If the load capacity needs to be increased, our company will customize products for customers.
