Whal will be the HRC fuse rating of a 3phase
415V,50Hz,0.85pf,95%efficiency,30KW,1450rpm induction
motor,starting with a DOL starter.and describe the Fuse
rating calculation.
Answer Posted / vishu
Calculate the rated current of the motor it will be 50A.
let us assume The permissible overload is 20%
then fuse rating will be 50*1.2= 60A
