3 nos of fuse are used in series with the motor circuit to protect the motor from external over current and short circuit faults. Also, 1 fuse is used to protect the control circuit of the wye-delta starter. 5. Push Buttons - to start (NO type) and stop (NC type) the motor.
Simple Star Delta Wiring Diagram Wiring Diagrams Nea
Principle of Working of Star Delta starter. The motor is first started by connecting its stator winding in a star configuration. The phase voltage in the star configuration is 1/ √ 3 of the phase-to-phase or line voltage. Thus the voltage applied to the stator winding is about 58 % of the line voltage. The starting stator current reduces to 1.

3. Size of Star Contractor. The third contactor is the star contactor and that only carries star current while the motor is connected in star. The current in star is 1/ √3= (58%) of the current in delta, so this contactor can be AC3 rated at one third (33%) of the motor rating. Size of Star Contactor= IFL x 0.33.
