M Rashwsn,
To put what my colleagues have said on non-country specific terms, contactors used for controlling motors must be selected based upon the listed and labeled motor POWER rating (be it HP or kW), not the current rating alone (with a nod to the outliers where the motor FLC is higher than normal). This is because there is more going on than simply the running current, and although not technically unacceptable, if you sized every contactor for the starting current, they would last forever but you may break your budget.
When a contactor is rated for a particular induction motor power rating at your given voltage, it is inherent in the design that the contacts will handle the FLC continuously as well as any LRC that a motor of that size will be expected to draw under normal circumstances.
From that point is where IEC rules and NEMA rule diverge. IEC sizing rules include a specifically detailed duty cycle capability, with limits on the number of cycles per minute and minimum times between cycles before you begin a de-rating process, so the selection involves some minor engineering function to know how they are intended to be used. NEMA designs are intended to take the absolute worst case scenario and survive, after being selected by an electrician with little or no engineering background nor concern for how it might be abused.
