Can I use an RIBU1C to switch a 110v fan?
Your proposed use of that relay looks fine.
The key item in the relay specifications is &quot;1/3 HP @ 120-240 Vac (N/O).&quot; That says that a normally open relay contact of that relay is rated for controlling a 1/3 horsepower motor powered from a voltage from 120 to 240 volts. 1/3 Hp is about 250 watts mechanical output of the motor. Your fan does not likely exceed that power level.
