Hi Tobias,

this is the information out of the "Juniper Tech Club" in Cologne in June 2016. So not only provided to us.
If needed I can verify that with Juniper.

>> MPC7E480G
>> In the non-redundant mode (so all three SCBEs are online and active) you will not suffer from any limitation as long as all three are online. But if one dies you will have the limitations in a Premium2 chassis. So it depends on the model you want to use. We need a full redundant switching fabric so we have to calculate with these limitations.
