  We present an analysis of production and signature of neutral Higgs boson
($H_{2}^{0}$) on the version of the 3-3-1 model containing heavy leptons at the
Large Hadron Collider. We studied the possibility to identify it using the
respective branching ratios. Cross section are given for the collider energy,
$\sqrt{s} =$ 14 TeV. Event rates and significances are discussed for two
possible values of integrated luminosity, 300 fb$^{-1}$ and 3000 fb$^{-1}$.
