Context :

Aims : The detailed analysis of all data taken by the XMM-Newton satellite of UGC 11763 to characterize the different components that are emitting and absorbing radiation in the vicinity of the active nucleus .

Methods : The continuum emission was studied through the EPIC spectra taking profit of the spectral range of these cameras .
The high resolution RGS spectra were analyzed in order to characterize the absorbing features and the emission line features that arise in the spectra of this source .

Results : A power law with a photon index \Gamma = 1.72 ^ { +0.03 } _ { -0.01 } accounts for the continuum emission of this source in the hard X-rays from 10 down to 1 keV .
At lower energies , a black body model with kT = 0.100 \pm 0.003 keV provides a good description of the observed soft excess .
The absorption signatures in the spectra of UGC 11763 are consistent with the presence of a two phase ionized material ( \log U = 1.65 ^ { +0.07 } _ { -0.08 } ; 2.6 \pm 0.1 and \log N _ { \mathrm { H } } = 21.2 \pm 0.2 ; 21.51 \pm 0.01 cm ^ { -2 } , respectively ) in the line of sight .
The physical conditions found are consistent with the two phases being in pressure equilibrium .
The low ionization component is more ionized than typically found for warm absorbers in other Seyfert 1 galaxies .
There are also signatures of some emission lines : O vii He \alpha ( r ) , O vii He \alpha ( f ) , a blend of the Ne ix He \alpha triplet and Fe xviii at \lambda 17.5 Å .
