Abstract
Timer for star-delta starters with contactors, essentially characterized by the fact of comprising an electronic timer circuit connected by one pole to the network, while the other supply pole is connected to the contactor circuit through a contact of line and a star contact whose closure is determined by the operation of the respective contactors, with the aforementioned triangle and line contacts connected to a trained minirel to compute the passage of the star contact current when contacting the triangle when receiving the signal emitted by the electronic circuit in a predetermined time, it being foreseen that when the start switch is pressed, the star contactor enters through a normally closed contact of the triangle contact, maintaining the operation of said star contactor despite releasing the pushbutton marching, through the mini-relay that initially contacts with the star contact through contacts activated by it, which in turn will determine the operation of the line contact that will be maintained when the open contact of the same is closed.
