The present invention relates to an electromagnetic contactor, and more particularly, to an electromagnetic contactor for star-delta driving, which is capable of rapidly and safely switching a connection of a 3-phase motor from a star connection to a delta connection and simplifying configurations of a connection circuit and an opening/closing device. According to the electromagnetic contactor for star-delta driving and a control device thereof of the present invention, the connection of the 3-phase motor can be switched rapidly and safely from the star connection to the delta connection, and the configuration of the connection circuit and a control circuit of a power supply thereof and a magnetic switch configuration can be simplified, and thus, there is an effect of saving space by reducing the size and weight of a product and reducing the numbers of power wirings and control circuit wirings. In addition, a magnetic switch between star and delta connections is interlocked by using a timer and an auxiliary contact, so as to improve the convenience of an operator and reduce construction time. In addition, because a timer base and the control device are ready-made in the form of manufactured goods, it is easy to use the products and there is very little risk of causing a misconnection in the control device. Thus, there are effects of improving the safety of a construction operator at a construction site and a general user, and improving driving components and circuit protection.
