Time delay RCD

The time dealy is done with a 'monostable'. The current transfomre drives a transistor that triggers the monostable, and once the capacitor has discharged enough, then and only then the contactor coil is pulled in..
Shorter delays might be an R_C time constant only, but I've never seen that.
