remember to consider the Load factor of the fan (if exist) And the relay current capacity.

How do you mean my friend?

 

He means that the relay switching capacity needs to take into account the power factor of the fan but this is such a small motor that any relay capable of switching > 2A or so will suffice. On a large motor the current could be significantly out of phase with voltage (ie poor power factor) and this can have detrimental effects on the switching contacts, eg bad arcing.

Ok it's well understood
