Question

what is the fuse rating of 10Hp 3 phase 415v squirel cage inductor motor​

HERE IS UR ANSWER

$_____________________________$

The motor you suggested (10 HP) is definitely a 3 phase motor because as per power rating is more than 1 HP. Single phase motors are general made up of fraction of 1 horse power.

10 hp induction motor fuse capacity can be found by the current rating of the motor . Just you need to find rated current and it can be found by equation,

P = √3 ×V× I× PF

therefore, Rated current capacity of motor winding on full load is,

I = P/(√3×V×PF)

>Now induction motor at a starting time takes 7 to 10 times more current than its above rating.

I' (for fuse ) = 10 × I

Therefore you will required fuses more than ,

10 times of above rated current equation . Below this current rating fuse might get burn and also not that too much high rating is not good as it will might not burn during its necessity during faults. Use already defined standards for fuses.

$\fbox{Note that you can get rated current directly by observing name plate of motor.</p><p>}$
