FIELD: protection of motor.
SUBSTANCE: winding of starter and ancillary relay are connected to all three phases behind terminals of starter. To start the device there is additional winding or double-terminal closing "start' button. Increased sensitivity of heat protection is provided by shunting of the button during starting. Increased speed of operation of electromagnet starter is provided by fact that its contact is not involved in operation during process of starting.
EFFECT: improved sensitivity; higher speed of operation.
