Abstract: We present a dilaton dominated scenario for supersymmetry breaking in a recently constructed realistic superstring inspired model with an anomalous $\mathrm{U}(1)$ symmetry. Supersymmetry is broken via gaugino condensation due to a confining $\mathrm{SU}{(N}_{c})$ gauge group in the hidden sector. In particular, we find that by imposing on the model the phenomenological constraint of the absence of observed flavor changing neutral currents, there is a range of parameters related to the hidden sector and the K\"ahler potential for which we obtain a low-energy spectrum consistent with present experimental bounds. As an illustrative example, we derive the low energy spectrum of a specific model. We find that the LSP is the lightest neutralino with a mass of 53 GeV and the lightest Higgs ${h}^{0}$ has a mass of 104 GeV.
