Rated current of the thermal relay setting according to the rated current of the motor, generally choose ( ) times of the motor rated current. A. 1.5-2.5 B. 3-5 C. 0.95-1.05 D. 5-7

For a thermal relay (also known as a thermal overload relay), the rated current setting is generally chosen close to the motor’s rated current to provide proper overload protection without unnecessary tripping.

The correct choice is:
C. 0.95–1.05

This range ensures that the thermal relay is set at or near the motor’s full-load current for accurate overload protection.
