Load-bearing steel beam

[RenePalmer]

Hello
I am planning an extension and need to know the load-bearing capacity of a steel beam.
In the construction drawing, it is specified as follows: 2INP26
Does anyone know the load-bearing capacity or the dimension of this beam?

INP 26 has a moment of inertia of 5740 cm^4, a section modulus of 442 cm^3, a cross-sectional area of 53.4 cm^2, and weighs 41.9 kg/m
