Dynamics of proton and electron energy spectra at acceleration in 3D reconnecting current sheet (RCS) is investigated simultaneously with the collective electric field effects. In addition to the drift electric field, a polarisation electric field caused by the electron and proton separation and small scale electric field caused by Buneman and low-hybrid plasma turbulences are considered. The polarisation electric field parameters and turbulence growth rate are linked to the parameters and locations of the particles drifted and accelerated in an RCS. The small-scale electric fields increase mostly electron energies up to tens MeV while the polarisation field accelerates mostly protons up to GeV energies. Particle distributions in an RCS and their energy spectra are presented for different magnetic field topologies and combination of electric fields.
