The mission of this design settles to descend to pass the right choice in calculation electric current at the work term that give after the construction pattern of the electric appliances, certain electromagnetism system with size and parameters of the Contact a system, on a foundation, make use of the PRO/ the software of E as to it's proceed the entity shape, counteract the limited a method as to it's proceed an analysis, join together the versa dint in characteristic in vacuum force characteristic match with the proceeding the excellent turning the design. Keywords: Current Relay； Electromagnetism System；Combination point System；PRO/ E assistance design.
