The asymptotic solution for the Coulomb problem with N > 2 charged particles in the final state is found. It is governed by the classical trajectories which describe the uniform scaling in time of all interparticle separations. Quantum fluctuations of a system in the vicinity of a scaling configuration result in nontrivial threshold laws for the break-up of a quantum particle into N charged fragments.
