Abstract
An electromagnetic contactor coupling device, in which electromagnetic contactors are put side by side with an interlock unit sandwiched therebetween for preventing the electromagnetic contactors from simultaneously turning on, and are integrally coupled to each other by a coupler. The device is arranged to have abutment portions wider at its rear end than at its front end so that, in order to prevent displacement of the interlock unit due to vibrations or the like, force for sandwiching the interlock unit is exerted on the interlock unit as the coupler is inserted between the electromagnetic contactors.
