replacing compressor relay


I need to replace a compressor relay for a small refrigeration system but unfortunately the part number was burned off when the thing fried. I was hoping to get some help in figuring out how to find a new one. The relay was made by MRKK, that's all I can make out. Here is a picture



And here is the information on the compressor:

NU-T131AME
100v
130w
50/60Hz
18.3/16.7A
HFC-134a

Any help is appreciated - thanks!

Go to the manufacturers website. they should have a listing of what potential relay and start cap to use.

replacing compressor relay


Thanks for the responses. Unfortunately the manufacturer is no longer around and I have not been able to find a service manual for the instrument (this is for a bench-top refrigerated centrifuge so it's not as common as say a household refrigerator). I have also not been able to find any information about the compressor.

The few relays I have found on the internet that look like this are specified by horsepower (found one listed for 1/5hp and one for 1/6hp). From the information I gave on the compressor, is there a way for me to determine the hp? If I have to guess at one of these to try as a replacement, is it better to go with the higher hp? Any suggestions how I go about replacing this relay, given the information that I have?

How many BTU is the system. Convert that to HP.
