This circuit is just an example of star delta connection relay for three phase motor. Used DC power supply to drive the circuit and AC supply for motor running. Around after 40 secs circuit shift from start to delta.

Try to layout the circuit so it's easier to troubleshoot and include a description of the "bug" so we may all learn and let the developer know what it is. Thanks

@wyoelk appreciate your reply. I figure it out that there is no problem with the 555 ic but with my circuit for disconnection, i will try to solve it. If i use 10mf capacitor its work fine but the time delay increased alot
