In this paper we consider a new model of nonlinear electrodynamics - "Hyperbolic-logarithmic". This model contain a three parameters and describe by following Lagrangian: ℒ = -ℱ - 𝛽 𝑎𝑟𝑡ℎ(𝛽ℱ) - 2𝛽 [ln(1 + 𝛽ℱ) + ln(1-𝛽ℱ)], where ℱ = 1 4𝐹𝑖𝑘𝐹𝑖𝑘. We show, that in this model dual symmetry is broken. Also we proved that the electric field of a point-like charge becomes non-singular in this framework, static electric energy of this charge is finite. We calculate a theory parameters values guided by electron parameters and Abraham - Lorentz idea about a pure electromagnetic nature of electron mass. We find the canonical and symmetrical Belifante energy momentum tensors.
