The gauge symmetry breaking in 3-3-1 models can be implemented dynamically because at the scale of a few TeVs the U(1)_X coupling constant becomes strong. The exotic quark T introduced in the model will form a condensate breaking SU(3)_L x U(1)_X to electroweak symmetry. In this work we explore the full realization of the dynamical symmetry breaking of an 3-3-1 model to U(1)_{em} considering a model based on SU(2)_TC x SU(3)_L x U(1)_X. We compute the mass generated for the charged and neutral gauge bosons of the model that result from the symmetry breaking, and verify the equivalence between a 3-3-1 model with a scalar content formed by the set of the fundamental scalar bosons (chi), (rho) and (eta) with a 3-3-1 model where the dynamical symmetry breaking is implanted by the system formed by the set of composite bosons (Phi_T), (Phi_TC(1)) and (Phi_TC(2)). In this model the minimal composite scalar content is fixed by the condition of the cancellation of triangular anomaly in TC sector.
