Abstract
Low voltage circuit breakers which interrupt fault currents rapidly ar e widely used in power distribution systems. It is necessary for the o ptimum design of circuit breakers to analyze electromagnetic forces on the contact systems equipped with are rupturing parts, In this paper, the forces generated by currents and flux densities are obtained by u sing the 3-D finite element method taking into account a current const riction and variations in are diameter, It is shown that the 3-D analy sis is capable of evaluating new design of contact systems.
