I don’t know the exact cause of the fire here, but would say that it was probably the result of some loose connections or malfunction of the overcurrent devices (CB’s).
The instructions on some equipment make it very clear that they want the installer to use their products, and no others. In those panels the note is specific, and in others there may be permission to use CB's from another manufacturer.
