IEE Regulations for Connecting 3 Phase 7.5kW 415V Induction Motor Without Overload Relay

What are the IEE regulations regarding the connection of a 3 phase induction motor please.

FLC = 14A

Voltage = 415 V

Power = 7.5

Can it be connected just using a circuit breaker and a contactor without an overload relay.

If it can be connected in this way what should be the size of the circuit breaker.

There is also a heater, how long the heater should be left on when the motor is not running.

Hi George-I apologize for the delay in responding.Here is a document that may be helpful: Requirements for Protection against Overload   I'm not an expert in this particular area, but what I **think** I understand is:
In this case you are not required to have a dedicated overload relay.
You should use a "Type C" circuit breaker.
I think 20 amps trip current should be appropriate since 3-phase motors generally don't have a huge starting inrush.I'm not sure I understand about the heater.  How is it related to the motor?

Thank you for your reply.The space heater is within the motor to prevent condensation.
