CalculationsCâu 15 / 110
A motor with a service factor of 1.15 has a nameplate full-load current of 34 A. What is the maximum overload protection setting at 125%?
a.34 A
b.39.1 A
c.42.5 A
d.45.9 A
Giải thích
For a motor with service factor 1.15 or greater, overload is set at up to 125% of nameplate FLA: 34 x 1.25 = 42.5 A.
