Compressor universal relay
« on: December 31, 2013, 03:04:22 PM »
What do you guys think about what these guys are saying about this relay and that 99% of all compressors are 1/3 to 1/4 hp?

I can't get that number to work. SUPCO? I use RO41 and works fine on most applications.

They are taking about this one that as no thermal protection and the main thing is that mosts compressors are 1/3 to 1/4 hp. power.Most modern compressor i would use the o.e.m relay and they are less h.p.and that relay replaces 99% I don't think so.

I use that relay fairly often. Usually on fridges that are 8 or more years old. I have not had any call backs in three years. I have probably used it 25 to 30 times.  Nowadays i try to use the original relay if I can.

These people are not even technicians and rather foolish to recommend an inferior device. These devices provide no thermal overload protection, and very poor power overload protection. If you live in a high power surge area like I do, you must be careful what you use to protect the compressor you are working on.
 Manufactures of most of the modern, fractional, high efficiency compressors use either a PTC start device with external klixon, or a packaged device like the WR09X10106 which contains a waifer ptc device and a klixon, which provides a nominal drop out current of 20 amps. These compressors,( except GE compressors which are impeadance protected) draw extremely high current at startup and must be protected. They do worst case analysis and want to make sure the compressor will survive a power surge, or loss of cooling. Compressors I work on range from .15 hp to more than .5 hp. For these, the ptc device and klixon must be selected carefully to ensure reliable starting and proper overload protection.
 In addition, the pinout of some compressors may not be the standard start pin on the bottom left.
 I stock a good selection of ptc devices and Klixons, but recently, I have been using a lot of the WR09X10106 box devices.

They misspelled supco and the part number is UPRO41. I would not use the hard start which is what this is. I have seen a couple compressors blow out the terminals with these. I carry the upro41 which has worked for me.

If I use a WR09X10106, I tell the customer they are getting the same part electrically that they had before. To prevent future failure, I recommend a 1000 joule surge protector in the wall outlet.
 You cannot say that when you use the UPRo41. This has no klixon that prevents overheating of the compressor by shutting down for a sufficient time to allow the compressor to cool.
 Manufactures use the more expensive item as they want more protection to the compressor.
 Using the UPRo41 is not an approved factory replacement item. They also get extremely hot and can cause a house fire.
 For really superior protection, I use the discrete ptc device and klixon.

I try to use original parts. In this case if they were better we would't be having this discussion.
