  "abstract": "The kaonic clusters $K^{-}K^{-}p$ and $ppK^{-}$ are studied based on the configuration space Faddeev equations for $AAB$ system. The relation between the doubled binding energy of the $AB$ subsystem $2E_{2}$ and the three-body binding energy $E_{3}(V_{AA}=0)$, when the interaction between the identical particles is omitted, is considered. The isospin-less model leads to the relation $\\left\\vert E_{3}(V_{AA}=0)\\right\\vert >2\\left\\vert E_{2}\\right\\vert$. For the kaonic clusters, described within isospin formalism, the relation $\\left\\vert E_{3}(V_{AA}=0)\\right\\vert~<~2\\left\\vert E_{2}\\right\\vert$ is satisfied. Thus, the binding energy of the kaonic system $NN{\\bar K}$ is limited by $|E_3|\\le |2E_2|$ due to a weak attraction of the spin singlet $NN$ interaction.",
