The stellar energy-loss rates $mathcal{Q}$ due to the production of neutrino pair in the framework of 3-3-1 models are presented. The energy loss rate $mathcal{Q}$ is evaluated for different values of $beta=pmfr{1}{sqrt{3}},pmfr{2}{sqrt{3}},pmsqrt{3}$ in which $beta$ is a parameter used to define the charge operator in the 3-3-1 models. The correction to the rate which is compared with that of the Standard Model ($de mathcal{Q}$) is also evaluated. We show that the correction does not exceed 14% and %is gets the highest with $beta=-sqrt{3}$. The contribution of dipole moment to the energy loss rate is small compared to the contribution of new natural gauge boson $Z$ and this sets constraints for the mass of Z $m_{Z} leq 4000$ GeV. This mass range is within the searching range for $Z$ boson at LHC.
