The Coulomb interaction between two protons is included in the calculation of proton-deuteron breakup and of three-body electromagnetic disintegration of {sup 3}He. The hadron dynamics is based on the purely nucleonic charge-dependent (CD) Bonn potential and its realistic extension, CD Bonn + {delta}, to a coupled-channel two-baryon potential, allowing for single virtual {delta}-isobar excitation. Calculations are done using integral equations in momentum space. The screening and renormalization approach is employed for including the Coulomb interaction. Convergence of the procedure is found at moderate screening radii. The reliability of the method is demonstrated. The Coulomb effect on breakup observables is seen at all energies in particular kinematic regimes.
