KB ELECTRONICSModel KBWC-110K (UR) Variable Speed Fan Control, Wall Mount, Rated 10.0 Amps @ 120 VAC for use with Shaded Pole and PSC Motors

will this switch work for the iLiving 4200 24 Variable Speed Shutter exhaust fan?

Can i use this speed control on a fantech fr250? it uses way less amps than this rated, but is it ok as long as i am under amp limit? can i go to big?

Will this work on a dayton 1tdu2 shaded pole psc blower, 3.7 amp and are there direction on how to wire it?

Is this on rated for 40 degree C?
