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

The media could not be loaded. This replacement was close match to the old part but it had a built-in on-off switch in the rheostat.Also had a ground wire which the original didn't have, most likely was required when the original unit was produced. So far it seems to be working fine on a cotton candy machine.

This was a replacement for the old one in my greenhouse. It arrived the next day and installed easily. My fans were up and running within minutes.

Todo muy bien...

I have a whole house fan that is about 30 years or so, old. It came with a KB speed control with identical electrical specs ( 10 Amps Full loadd, 20 Amps locked rotor load), but its aluminum heat sink and control plate was only the width of a single gang switch plate. This new one has the visible items mentioned that are double the width. The next smaller model is rated for 8 Amps. This new one is still made by the same manufacturer!My original speed control failed after about 20 years of use, but its on/off switch was still able to turn the fan on at full speed, and turn it off. I guess the manufacturer finally decided that that the electronics in this unit would have a longer life with a double size heat sink.In any case, the unit works perfectly for me, and the electronic package at the rear, still is designed to fit into a single gang electrical box. For years, I just thought that the failed unit was not able to be replaced, but when I searched recently, there it was on Amazon, and at a great price too.

Big, and bad ass. The smaller motor controllers get warm and fail. This one powers my 5ft diameter 2hp propeller fan at any speed like it's nothing.

Easy to install, fits into existing single switch box. Old switch with just flush faceplate got hot to the touch. This one with large heat sink stays cool. I like the way it looks on the wall. Need about 2.5 inches of clearance from center of box.

Works fine with a Portacool A/C.

I previously had a smaller version of this for our whole-house fan for 15+ years. Though its 6A rating should've been sufficient for the fan (like 40% overkill), the control would get disturbingly warm. This 10A version doesn't have any noticeable increase in temperature with the operation of the fan, probably because the air flow by its heat sink, and that makes me much more confident.
