WebThe fuse rating calculation or fuse sizing formula is the 1.25 times of the FLA for motor, 2 times of the FLA for transformer, 1.5 times of the lighting load. ... Let we calculate the fuse sizing for 5.5kW 415V three-phase induction motor is planned to run at 0.86 power factor. Fuse rating = 1250 x 5.5 / (1.732 x 415 x 0.86) = 11.1 A. Hence, we ... Weband the motor’s Service Factor (SF), should be sized at 115% or less of motor FLA for 1.0 SF or 125% or less of motor FLA for 1.15 or greater SF However, as shown in Curve 2, when fast-acting, non-time-delay fuses are sized to the recommended level the motors inrush will cause nuisance openings.

WebSince the overload current rating cannot be greater than 125% of the FLA, engineers can choose the next lower circuit breaker rating, for example, 31 A. Note: Motor full load amperage ratings can easily be obtained from the motor nameplate or through calculations. Engineers can also obtain these ratings by contacting motor manufacturers.
