MCB, MPCB (Panel Design)

To protect your 2HP motor the first and important parameter to know is the nominal current of motor at full load.This information should be printed on motor performance label and you should find different current rating in regard of nominal voltage.
Then it depends if you select an MPCB (Motor Protection Circuit Breaker ), MCB ( Minaiture Circuit Breaker ) or MCCB ( Molded Case Circuit Breaker ).Some of them protect only for short circuit and some of them protect for short circuit and thermal overload.- If you select the Circuit Breaker with thermal protection embeded you just need a contactor to switch "ON/OFF" your motor.-

If you select the circuit breaker withtout thermal protection you need to add an overload protection relay to protect your motor agaisnt overload and the contactor to switch "ON/OFF" your motor.- You should never use a circuit breaker to switch "ON/OFF" a motor. The circuit breaker is not designed for this and will wear faster than normal.- Your motor starter shall always include a contactor to switch "ON/OFF" motor.
Now you have selected the Circuit breaker with or without thermal overlaod.

You will have to know :

1 - Motor inrush current can goes up to 8 x In ( In = Motor nominal current at full load. Motor plate label information ). This value could be higher with poor quality motors.

2 - MPCB ( Motor protection Circuit breaker ) are designed to accept this inrush current without tripping.If you select electrical protection circuit breaker you may face nuisance tripping on motor starting.

3 - Your Overload protection separate or embeded in the circuit breaker shall be adjusted to motor nominal current.

In conclusion- The circuit brealker shall accept inrush current and shall have a setting range which include the motor nominal current.

Hope this will help
