Abstract
Motor start circuit for an induction motor, particularly a single-phase AC induction motor, with a main winding () and an auxiliary winding (), which are supplied with current, particularly alternating current, via current supply connections (), and with a start switching device () serving the purpose of interrupting the current flow through the auxiliary winding () after the start of the motor, the start switching device () being connected to a control device () via a connector (), the control device () being connected between the current supply connections (), and with a winding protection switch (), which is normally closed and which opens on the occurrence of a fault. The invention is characterized in that the control device () is connected to the winding protection switch () via at least one further connector (), preferably via at least one further connector () and the auxiliary winding ().
