If you want to control induction motor using a control relay give neutral directly to the one point of coil of relay & one point of coil of contactor then give control supply through push button to second point of coil of relay. use one NO point of relay and give supply to coil of contactor. and also use one NO of contactor for holding the contactor & take OFF (NC) in the starting to stop motor after complition of work.
It is jut like an Direct On-line starter.

What is a motor thermistor?
It is a device used to sense the temperature within the motor coils. There are usually three in a three phase motor, one for each coil. The output of the thermistor is used to hold an over temperature relay designed to be used with thermistors, in a closed position. The start circuit of the motor control is connected thriough this relay through N.C. contacts. If the motor goes into a over heat condition then the control relay drops out, the contacts of the relay open which in turn de-energizes the magnetic contactor and disconnects the motor from the supply voltage.
